1. Summary of Pope Innocent III’s confirmation of  Bishop Albert of Riga`s agreement with the Swordbrothers, 19 October 1211 
From: The registers of Innocent III, published as ‘Liber  registrorum sive epistolarum’, no. 141, 3 vols in Patrologia Latina, ed. J. P. Migne, vols 214-216: here vol. 216,  cols 325-6.
Summary: The pope states: ‘A controversy arose between you and the brothers of  the knighthood of Christ over the division of lands which through the grace of  the Holy Spirit were recently converted to the worship of the faith of Christ.  However, following our investigation and with our mediation, at last you came  to this agreement:
1) that the Brothers should hold one third of those  lands of Lettia and Livonia from the Bishop of Riga, and give no military  service for them except what is intended for the defence of the Church and the  province in perpetuity against the pagans, but their master for the time being  should always promise obedience to the Bishop of Riga.
2) The Brothers and clergy who administer spiritual  things should not pay the bishop tithes, first-fruits, offerings nor cathedral  dues. The colonists of the brothers` third should pay tithes to their churches  from the part of the produce belonging to them. From this they should pay one  quarter to the bishop unless the bishop decides for some necessary and  reasonable cause and by his own free will that it should be remitted.
3) The Brothers and their successors will have the right  of presenting suitable persons to the Bishop of Riga for the aforesaid churches  when they are vacant. The bishop should not put off vesting these persons with  the cure of souls.
4) Moreover, when the bishop or any of his men decide to  visit, the Brothers will entertain him in their house with twenty mounts, once  a year. They will entertain him in their parishes twice a year.
5) As for lands which the Brothers acquire with the help  of God outside Livonia or Lettia, they will not answer to the Bishop of Riga  for these, nor will he trouble them in any way over them. But they will obey  what the apostolic see (the Pope) tells them.
6) The Brothers will obey the rule of the Knighthood of  the Temple, but will have a different symbol on their habit, to show that they  are not subject to them.
7) The Brothers will have free burial also for the use  of their Brothers and families, and also of those who choose to be buried in  their house, saving the canonical portion due to the churches from which the  bodies of the dead are taken (i.e. death duties payable to their own church).’
The pope approves this agreement.
2. Summary of the confirmation by the emperor  Frederick II to Volquin, master of the Swordbrothers: May 1226
From: Historia  diplomatica Fridericii secundi, ed. J. L. A. Huillard-Bréholles, 6 vols in  11 (Paris, 1852-61, repr. Turin, 1963), vol. 2.1, pp. 583-5; also in Tabulae ordinis Theutonici ex tabularii  regii Berolinensis codice potissimum, ed. Ernst Strehlke (new ed., Toronto,  1975), p. 229, no. 235: CR4759.S8
Summary: Frederick II, emperor, confirms to Volquin, master of the house of the  knighthood of Christ in Livonia, and his brothers, all possessions and rights  which they possess from the bishops of Livonia and the Isle of Oesel or will  acquire justly in the future and also gives them any metal ore which can be  found in the ground or above ground in that district.
  
  He says that although he ought to favour all religious  men, he should especially favour those who do not only fight against invincible  foes but our visible foes for exalting the faith of Christ and the religion of  the Christian faith, by exposing their souls for Christ`s sake and their  persons for the sake of God`s faithful.
Therefore, at their request he confirms their  possessions and rights:
‘considering the agonies which the master and brothers  frequently sustain for the faith of Christ, and how their forces are necessary  to comfort the Christian region and defend those in those parts who are newly  converted to the Christian faith, for reverence of God and the sake of eternal  reward...’. 
  and the sins of himself and his family. Witness no.10  out of 17 is Brother Hermann, master of the Hospital of Saint Mary of the  Teutons (i.e. the Teutonic order).
From: Les  registres de Pope Gregory IX, ed. L. Auvray, 4 vols (Paris, 1896-1955), no.  2287, pp. 1201-9. 
Summary: This is a summarised schedule of the charges to which Nicholas, bishop  of Riga, the brothers of the knighthood of Christ of Livonia [i.e., the  Swordbrothers] and the citizens of Riga are to reply in the Pope’s presence.  [These charges are based on the accusations with Baldwin of Alna, bishop of  Semigal and papal legate, had brought against the Swordbrothers, the bishop of  Riga and the merchants of Riga.]
Following an  investigation and judicial judgement, Baldwin of Alna, who was bishop of  Semigal [in southern Livonia] and papal representative or ‘legate’ in Livonia,  restored to the bishop of Riga the hostages given by the prince of Kurland  [south-western Livonia] - who belong to the Church of Rome. The bishop gave to  the brothers of the knighthood of Livonia and the citizens of Riga each one  third of the hostages and one third of the said province and kept one third.
  The master  and brothers are now summoned to appear in the papal court, charged with the  following:
1) They restored the lands of Vironia [northern Estonia]  and Gerva [Jerwia, Jerwen: to the south-west of Vironia] to Baldwin of Alna,  bishop of Semigal, at the order of O., cardinal and papal legate, but later  snatched them back by violence.
2) They usurped the province of Kurland, which had  voluntarily converted to the Roman Church. And when Baldwin bishop of Semigal,  legate of Pope Gregory IX, went to Rome they launched a raid on it, burning,  looting etc. and reduced the new Christians to servitude.
3) They called in Revalia [Reval, on the north coast of  Estonia] 200 merchants who were occupying lands which had been given to them in  Gotland [an island in the Baltic, between Livonia and Sweden], and gave them  fiefs in Gerva, in prejudice of the Roman church.
4) In order to take over the land of Vironia, they had  100 or more vassals of Vironia killed. Yet, as the people there are new  converts, Veronia actually belongs to the Church of Rome.
5) At the Pope’s intervention they voluntarily restored  Vironia, Gerva and Kurland to the bishop of Semigal, who was then papal legate.  But afterwards they attacked these areas, in prejudice of the Church and  oppressing the new converts of Gerva and Vironia. In one expedition they  inflicted four hundred uncos’ worth  of damage on them. [The uncus was literally  an ounce; in this case it is the local currency, an ounce of silver.]
6) They took from the vassals of the bishop three  quarters of the castle of Reval, which the vassals of Vironia and Harria  [western Estonia] and Revalia had restored to the bishop. The bishop had  recommmitted the responsibility of guarding this castle to these vassals.
7) They refused to restore one quarter of the castle.  Because it was held by the king of Denmark from the Roman Church on the  authority of Master John, papal legate, they and the bishops and other Germans  attacked it. The Brothers received from the Danes the responsibility of  guarding it.
8) When a dispute between them and Bishop Baldwin  (representing the Church) was ended by arbitration, they captured his master,  superior and primary, and refused to restore one quarter of the castle, as had  been stated in the arbitration. And when peace had been made they occupied the  three quarters of the castle of Reval treacherously and in prejudice to the  Church and killed more than 100 vassals of the Church of Rome, infringing the  parish in eight places and shedding blood both in the cemetery and in the  church over the altar. Heaping the corpses in a pile, they placed on the top of  the pile one of the dead who had been the most faithful to the Roman Church and  was like a vicegerant of the lord Pope. And to bewilder the Church they would  not allow them to be given burial, so that as time passed the new converts and  others, Prussians and pagans, would come to see this spectacle and think them  [the Swordbrothers] greater than the Church of Rome.
9) They not only took over the castle of Reval violently  and treacherously but also took three thousand marks of silver, 200 warhorses,  250 other horses, 400 sets of armour, the goods of many merchants, all the  citizens’ clothing, also the women’s clothes, and the ransoms of 200 vassals of  the Church, whom the Brothers captured: all estimated at a value of 15,000  marks.
  [A mark was two-thirds of a pound.]
10) They destroyed the castle of Hagelite, which had  been built by Master John, the papal legate. By that expedition and destruction  they damaged the Roman Church and its vassals and the new converts to the tune  of 2,000 marks of silver.
11) They usurped again the lands of Vironia and Gerva,  which they had restored at the Pope’s order to the said Bishop Baldwin of  Semigal, and detained them violently and oppressed the new converts of Gerva  because they had adhered to the Church and because they have no hope of  obtaining further lands.
12) They forced the vassals of the Roman Church in  Vironia, Harria and Revalia to give up their homage to the lord pope and they  forced the vassals to deny the fealty which they had made to the Pope through  Master John. The Brothers expelled those who would not deny the Church, and  took their moveable and immoveable property.
13) In Gerva - which belongs to the Church - they gave  fiefs to 40 merchants [which they had no right to do, as it was not their  land], which oppressed the new converts.
14) They took these same vassals away from the service  of God and the Faith, even though the bishop of Semigal had originally brought  these vassals into the neighbourhood of the new converts and pagans and given  them fiefs from property in his diocese so that they could crush the pagan’s  attacks. And with the aid of these vassals the Swordbrothers opposed the Church  of Rome.
15) They conspired with Lord Nicholas, who acted as  bishop of Riga, and the Rigans against the Church, and gave 71 merchants fiefs  in one part of Semigal and Kurland and 56 merchants fiefs in another part,  taking the rest of the land for themselves and the conspirators, not leaving  the bishop of Semigal or the Church a foot’s space, nor even the vassals put in  there by his predecessors.
16) They destroyed the castle of Godenbeke [Goldenbuke]  which belonged to the Church, and did more than 1000 marks’ worth of damage on  the church and vassals and new converts.
17) They called Russians, heretics and pagans around to  come and fight against the bishop and the cathedral church of Leal [in western  Estonia], the vassals and new converts of the church. They had the castle of  Tarbate [Dorpat in south-eastern Estonia?] fortified, using artifices, public  instruments and expense on behalf of the Russians and pagans, had provinces  depopulated and 450 new converts captured and killed, notwithstanding that  papal letters commanded that the bishop of Leal was to work with the bishop of  Semigal to crush the malice of the Brothers of the knighthood.
18) They took the goods of the castle of Dünemünde,  which belongs to the Cistercian order, both  moveable and immoveable property, estates and towns. And they captured the  converts and tortured them because the abbot of the place had cooperated with  the bishop, following the instructions in papal letters to him. Because of  this, unless the convent  of Dünamünde  received speedy help, it would have to leave Livonia and be split up between  various houses. Moreover, on Christmas Eve the Brothers killed the cellarer of  the abbey, who was then promoting the affairs of the Roman Church.
19) They occupied the villages of the church of Riga and  took moveable and immoveable goods, despoiling and depopulating the new  converts, because the provost and convent of the church had faithfully stuck by  the Roman Church.
20) With the help of the Russians and aforementioned  pagans, they completely destroyed the monastery of Valhena [?], which belonged  to the Cistercian order, reducing the edifice to nothing by fire. The monks at  once emigrated from Livonia to Teutonia [Germany], unable to take anything with  them but not able to delay.
21) Whereas Sakala, Vaigele, Moghe [Moke], Nonnegunde,  Alempoisio, Silia, Semigal and Kurland and all the other provinces in Livonian  parts which had been converted to the faith by preaching or pilgrimage  [crusading] belong to the Roman Church, the Brothers are said to possess these  provinces de facto, some in part,  some completely, in prejudice to the Roman Church. So when they appear before  the pope they must bring legal instruments, witnesses or reasons, to establish  their claim if they have any right there. Similarly for the lands converted  later.
22) Almost seven years or more they had held part of the  episcopate of Reval and Oesel after expelling the bishops, against right,  usurping the tithes, spiritual rights and episcopal jurisdiction in them.  [Oesel is a large island just off the coast of Livonia.]
23) They choose temporal lords over the provinces of  Livonia and Estonia, obtaining an official letter from one of them, i.e. the  duke of Saxony, which stated that all the possessions of the Brothers ought to  remain with them forever, with all rights. They enslaved bishops, churches and  new converts as far as they could.
24) Whenever pagans were converted, instead of tithes,  they made an agreement with the new converts to pay an annual cens [land rent]  and absolved them from paying tithe. [The tithe would go to the Church; so the  Brothers preferred to collect rent, which could not be claimed by the bishop.]
25) They did not allow the pagans of Bandure, who were  their de facto subjects, to be  baptised, nor, consequently, did they allow them to be subjected to the Church,  and thus deprived the Church of the ‘cens’ [land rent] they took from the  pagans, notwithstanding that they had been received into the Catholic faith and  subjected to the Roman Church through the bishop of Semigal, who was papal  legate at that time. [i.e., although  the people of Bandure had been converted they continued to treat them
  as pagans.]
26) They did not permit any pagan from the provinces of  Kurland who required baptism to be baptised by the bishop of Semigal, who was  then legate. They did this so that they [the Brothers] could possess them  freely. [As soon as the pagans were baptised they had to be freed from slavery;  so the Brothers would not allow them
  to be baptised.]
27) They many times impeded the pagans’ messengers who  frequently wished to come to the Roman Curia to make a pact of liberty and  receive the Christian faith, saying to them that they could give them as good a  faith as the pope, so that when they had reached Gotland they were forced to  turn back.
28) When pagans were converted to the faith by the  Brothers they were given their liberty, but at the slightest excuse they were  returned to servitude.
29) When the pope instructed the bishop of Semigal to repress  those who were oppressing the new converts and improve the converts’ situation,  the Brothers did not allow the converts to appear in court on the set day but  put many who were coming to the court in prison.
30) The Brothers demonstrated in many ways that they  were schismatics: opposing the Church, leading mercenaries against the Church,  and compelling the new converts of the Church and their vassals and even some  pilgrims [crusaders] to resist the said Church.
31) When one of their number killed their first Master  and his priest, they put their second Master, named Volquin, who is master now,  in prison and held him there for three months because he was more favourable to  the Church of Rome and wanted to keep the peace which had been made and not consent  to the treason the Brothers had conceived of killing the vassals of the Church.
32) Brother John ‘Selich’, and Jo. Sengelin, H.  procurator of Haria, Abraham and other brothers of his, are known to be guilty  of heresy and were peremptorily summoned to Rome to purge themselves. The  Brothers are holding them and guarding them, even though a sentence of  excommunication has been passed on them because they refuse to clear themselves  or to appear.
33) The Pope summons the brothers to give satisfaction  for a sum of 10,000 marks of silver for damage they caused to the Roman Church  and for other causes, following which a case was sought in the presence of an  arbitrator for the Roman Church, the bishop of Semigal, then papal legate.
34) They are to present to the Pope letters regarding  the restitution of Gerva and Vironia, which through some iniquitous judgement  they extorted from the bishop of Semigal when he was vicelegate. No less, they  are to restore to the Pope the letters recording the rights which the same  bishop conferred on the Cirrones, confirmed by his seal and that of the  prelates of Livonia and their brothers. The same Brothers took these letters  from the Cirrones in scandal to the pagans and their converts and detriment to  the faith, through the violence of their raid and not without spilling of  innocent blood.
35) They blinded Lenderus, vassal of the Roman Church,  and took all his goods, moveable and immoveable, because he was the first to  announce the papal legate`s arrival.
36) They are summoned to reply to the Pope re 1,000  Oserinis [Oesering - a coin] which they extorted from the Oeselians, impeding  their baptism by not allowing them to enter the Christian faith until they had  paid the money. This is reckoned at 500 marks of silver.
37) They are to give compensation to the Roman Church  for 14,000 silver marks they took from the produce of the province of Sachele,  which belongs to the Roman Church.
38) The sum which the Brothers are held to satisfy the  Roman Church amounts to 45,000 marks of silver.
[He then summons the citizens of Riga for taking one  third of the island of Oesel.]
39) He summons the Brothers of the Knighthood to show to  the Pope and his brothers [the cardinals] all their legal instruments [i.e.  charters showing their rights], if they have any, which they drew up so that  they could obtain whatever they intended to take over or keep in the lands in  Livonian parts which had been converted and were still to be converted; since  the Roman Church recognises no possessions of the Brothers in those lands  outside Livonia and Lettia.
40) He summons them to answer to all the charges brought  against them by the Roman Church, the king of Denmark, prelates, ecclesiastical  persons, vassals of the Church and new converts and any others.
41) They damaged Jo., knight of Boheshovede  [Bechehovede] to the tune of 200 marks of silver, because his son cooperated  with the legate in resisting the Brothers of the Knighthood.
He summons by name [various men, including the  following:] the priests of the Brothers of the Knighthood ... Master Lunderus  and Master Jo., brothers of the Knighthood ... to give testimony of the truth.
1. Summary of the Golden Bull of Rimini, March  1226.
From: Historia diplomatica  Fridericii secundi, ed. J. L. A. Huillard-Bréholles, 6 vols in 11 (Paris,  1852-61, repr. Turin, 1963), vol. 2.1, pp. 549–52.
  The emperor Frederick II conceeds to Hermann, master of  the house of St. Mary of the Teutons and his Brothers the authority to receive  the land of Culm and all the land which Conrad Duke of Masovia and Cujavia  promised and offered to the house, and also of invading Prussia and exercising  due rights of the emperor without paying any service or tax: March 1226,  Rimini.
Summary: God, the emperor Frederick says, established his empire and government  to magnify His name and amplify His faith in the Gentiles – non-Christians- so  it is his (Frederick’s) duty to turn his attention to the preaching of the  Gospel. As he intends to repress as well as to convert the Gentiles, he is  giving an indulgence through which Catholic men may take up the labour of  subjecting barbarian nations and reforming divine worship and exposing their  own goods and persons in this cause. So he wishes to inform present and future  men of the empire that his faithful man Brother Hermann of Salza has explained  in his presence that Duke Conrad [of Cujavia-Masovia] has promised and offered  the Brothers the land of Culm, which is within the frontier territory and  boundaries of Prussia, intending that they should take up the work and press on  with the opportunity to enter and obtain the land of Prussia for the honour and  glory of the True God. But they have put off taking this gift so as to ask  Frederick’s permission first.
  Because of the Master’s prompt and displayed  devotion with which he burns fervently to acquire that land for his House in  order to serve the Lord, and because Frederick is confident in the Master’s  prudence – because he is a man powerful in work and speech and he will  powerfully begin and complete the conquest for the Lord although many have  already failed in the same business with greater labours – Frederick gives his  authority for the invasion. He also gives the Brothers his imperial rights over  mountains, plains, rivers, woods and the sea, which they will hold free of all  service and exaction and they will be held to reply to no one. When they have  conquered the land they can take tolls, set up markets and fairs, coin money,  exact tallage and other rights, etc., create judges and rectors to whom the  people will be subject, both those people who convert and those who do not; and  the brothers may lay down good usages and customs and hold assize and make  statutes to strengthen the believers and keep the peace. 
2. Summary of the complaints of Bishop Christian  against the Teutonic Order.
Source: Preussisches  Urkundenbuch, ed. A. Philipps et al.,  6 vols (Königsberg, Aalen and Marburg, 1882-1986), vol. 1.1, no.134.
  Pope Gregory IX writes to the bishop of Meissen, the  provost of the cathedral and the provost of St. Afra, re the complaints of  Bishop Christian of Prussia against the Teutonic Order: 11 April 1240. 
Summary. Bishop Christian complains that:
  1) The Teutonic Brothers have not allowed new converts  to be baptised, claiming that they can be stronger as lords of pagans than of  those who believe in God.
  2) The Brothers afflicted with various tortures the  newly-baptised and new converts who had given oaths of fealty to the bishops,  unless they agreed to obey the brothers. On account of this many were forced to  return to their errors (i.e. paganism) through fear.
  3) They impeded pilgrims [crusaders] from building  churches and ensured that those they did construct were left to the pagans. 
  4) Although the Bishop had conceded certain episcopal  rights to the Brothers on certain agreements, by which the Brothers undertook  to enlarge the bishopric, attack the pagans and defend the preaching of the  gospel of peace and the Catholic faith, the brothers did not defend him when  the Prussians captured him, nor even ransom him when they received papal  instructions to do so.
  They allowed certain Prussian nobles whom they  could have exchanged for the bishop to go free in exchange for money, and they  killed a certain newly-converted noble, who had given his son as a hostage for  the Bishop, because they could not extort as much money from him as they  wished.
  5) While the Bishop was in captivity, the brothers and  some new converts invaded the Bishop’s church and land, the city and castle of  Sanctir, and looted all the moveable property they could find, and detained the  Bishop’s rights, tithes and other revenue by violence. They detained the whole  of the land of Prussia, against their agreement.
  6) Although they had received many benefits in the land  of Culm in order to defend the honour and rights of the Bishop of Prussia, they  were so ungrateful that not only did they not do the due service but they  prevented pilgrims from having recourse to the bishop.
The Bishop appealed for papal assistance. The Pope gives  instructions that the Brothers are to cease from molesting the Bishop, and give  compensation for the damage they have done, especially since they are giving  themselves a bad reputation for lack of devotion to God and men when they  damnably persecute the Bishop who is said to have increased their wealth in  many respects while remaining poor himself.
3. Summary of Duke Semovit of Masovia’s defence of  the Teutonic Order.
From: Preussisches  Urkundenbuch,1.2: no. 62, pp.  56-7
  Duke Semovit of Masovia writes to Pope Alexander IV to  protect the Teutonic Order against the machinations of certain people who have  attacked the brothers at the papal court: 17 July 1258. 
Summary: Duke Semovit writes that as the state and prosperity and salvation of  his country and the countries adjacent to their lands depend on the renown and  prosperity of the Teutonic brothers, he cannot fail to be concerned about these  accusations. He talks of the Order’s magnificent struggles against the  Prussians, with the standard of the holy cross in hand. The laws the Brothers  impose on the new converts, and their rights and customs, which they teach  them, do not deviate from the rite of true Christians. He does not believe that  those who have left many great dignities of the world, lordships and honours,  in order to spread the Christian faith, exposing not only their property but  their own lives to various deaths every moment, would violate the statutes of their  profession or would be found acting contrary to their profession. He asks the  pope not to allow any fabricated detractions against the Brothers to be  repeated to his ears.
4. The Franciscans of Thorn defend the Teutonic Order:  summary
From: the same, no. 65.
  The Guardian of the Minorites (Franciscans) of Thorn and  the brothers of the Franciscan convent in Prussia write to Pope Alexander IV.  They defend the Teutonic Order against the accusations made against it before  the Pope: 28 July 1258. 
Summary: they state that Brother Gerhard the commander, and the Brothers of the  Teutonic Order are not a little perturbed by the calumnies and false  accusations which have been undeservedly made against them. Since the Brothers’  tranquillity and peace is without doubt the tranquillity and salvation of the  adjacent provinces, ‘who place themselves like an impregnable wall against the  enemy for the house of Israel’ (i.e. Christendom), the Friars are writing this  letter in the Brothers’ defence without being asked.
  The wording is not identical to the previous  letter but identical phrases are used. This letter also talks of the Brothers’  magnificent struggles against the Prussians with the standard of the holy cross  in hand, and the laws they impose on the new converts which do not deviate from  the rite of true Christians. The friars know this for a fact.  They also refer to them spreading the  Christian faith as in the previous letter, and emphasize that the brothers have  left much and great dignities in the world, and say that they expose their  property and bodies. ‘So God forbid that they should violate the statutes of  their profession and would be found acting contrary to their profession.’  Furthermore:
  1) How could it be true that they would prohibit the  preaching of God’s word? – since they most earnestly encourage religious and  learned ecclesiastics to join them, especially if they can find any who know  the Prussian language for teaching the people the orthodox faith.
  2) They are not slow in carrying out papal commands,  since they honour the Holy Roman Church as lord and master, love its messengers  and observe imperial orders in all their deeds especially those made with Papal  approval.
  3) It is not true, as it was claimed, that the Brothers  prohibit the correction of incest and adultery and similar things, since they  mortify such things in themselves and hunt them out of others.
  4) They never forbid oratories to be built or catholic  ministers set up in them, who administer the Christian sacraments.
  5) The Friars deny that the Brothers destroy old  churches.
  6) The Brothers do not impede the sacraments of burial,  confession, baptism, Eucharist and the rest; this would be irrational since  they are faithfully intent on all the rites of the Church.
  7) They do not oppress the new converts by enslaving  them, since they give them the true liberty with which Christ freed us, if they  have the chance, even when they don’t want it and refuse it. And they provide  mercifully and paternally for them in all spiritual and temporal matters.
The Friars end their letter by pleading that the pope will  deign to show favour on the Brothers of the Teutonic Order, since the Brothers  are the prison and chain of the barbarians, and their role is to lead the  barbarians willingly into captivity in the Lord’s flock.

For  the background to this, see Benjamin Z. Kedar, Crusade and Mission: European Approaches towards the Muslims (Princeton, Princeton U.P., 1984), pp. 177-80.
  From: The Opus Majus of Roger Bacon, ed.  John Henry Bridges, 3 vols (Oxford, 1877-1900, repr. Frankfurt, 1964), vol. 3,  p. 121-2, part 3, ch. 13.
[Roger Bacon is discussing the importance of learning  other languages. He says that the third reason for needing to learn languages  is to convert the infidel.]
‘And so an infinite number of Jews perish among us,  because no one knows how to preach to them, nor to interpret the scripture in  their language, nor to confer with them nor dispute...’.
  [He points out that our religion came from their  religion, they are from the seed of the patriarchs and prophets, Our Lord was a  Jew, as was the Virgin and the apostles and innumerable saints.]
‘Also Greeks and Russians and many other schismatics (those who call  themselves Christian but do not recognise papal authority) remain in error  because there is no one to preach the truth to them in their language; similarly  with the Saracens and pagans and Tatars and other infidels throughout the whole  world. 
‘Nor is war against them any use, since sometimes  the Church loses out in Christians’ wars, as often happens Overseas [i.e. in  the Holy Land] and especially in the last expedition, i.e. the lord King of  France’s, as the whole world knows [Louis IX’s first crusade]; and even if the  Christians conquer there is no one who defends the occupied lands. Nor are the  infidels converted thus but killed and sent to hell. But as for the rest who  survive after the battle, their sons are stirred up more and more against the  Christian faith because of those wars, and move an infinite distance away from  the faith of Christ, and are inflamed to do every evil which they can against  the Christians.
‘So the Saracens, because of this, become  impossible to convert in many parts of the world, and especially Overseas and  in Prussia and the lands bordering Germany, because the Templars and  Hospitallers and the brothers of the Teutonic order much disturb the conversion  of infidels because of the wars which they are always starting, and because of  the fact that they wish to dominate them absolutely. For there is no doubt that  all the infidel nations beyond Germany would have been converted long ago, if  it was not for the violence of the brothers of the Teutonic order. The pagan  race has many times been ready to receive the faith in peace after preaching,  but those of the Teutonic order do not wish to allow this, because they wish to  subjugate them and reduce them to slavery. By subtle persuasions they have  already deceived the Roman Church for many years. That is known, otherwise I  would not write this.
‘Besides, faith does not come into this world  through weapons but by simple preaching, as I have shown.
