Next day, another message came from the khan, desiring again to know on what account I had come to his court; to which I answered, that this might be known from the letters of Bantu. But they said that these letters were lost, and the khan had forgotten their contents, and would know of me. Somewhat emboldened by this, I said, "The duty and office of our religion is to preach the gospel unto all. Wherefore, having heard of the fame of, the Mongals, I desired to come to them; and hearing that Sartach had become a Christian, I directed my journey to him, and my sovereign the king of the French sent him letters containing good words of friendship, testifying what men we were, and requesting we might be permitted to remain with the people of Moal That Sartach had sent us to Baatu, and he had ordered us to Mangu-khan, whom we had entreated and still do entreat to suffer us to stay." They wrote all this, and made a report of it to the khan. On the morrow he sent again that he knew we had no message for him, but came to pray for him as other priests did, but desired to know if any of our ambassadors had ever been in their country, or any of theirs in our parts. Then I declared unto them all I knew respecting David and Friar Andrew, all of which was put down in writing and laid before Mangu. They came back, saying, "Our lord the khan thinks you have staid long here, and his pleasure is that you return into your own country; but he desires to know whether you would conduct his ambassadors along with you." To this I answered, that I dared not to carry his ambassadors beyond his own dominions, as a warlike nation dwelt between their country and ours, between the sea and the mountains, and being only a poor monk, I could not take upon me to be their guide. This they likewise set down in writing and carried to the khan.
The Nestorians were commanded to set down in writing all that they would speak in favour of the Christian religion; and they wrote out a chronicle from the creation of the world to the passion of Christ; and passing over the passion, they spake of the resurrection of the dead, and of the day of judgment. Finding many things wrong, I pointed them out, and we wrote out the creed or symbol. Asking them how they meant to proceed in the conference, they said they meant to begin with the Saracens; but I dissuaded them from that, because, as they agreed with us in the belief of one only God, they would assist against the Tuinians. I then pointed out to them the original of idolatry in the world; and they desired me to explain these things before Mangu, and then to let them speak, because I should find it difficult and tedious to speak by an interpreter. I then proposed to try them, by taking the side of the Tuinians, while they should defend the opinions of the Christians; but they knew not how to prove any thing, except merely by quoting their Scriptures. To this I said, that these men believed not in our Scriptures, and would oppose them by advancing contrary opinions and positions from those books which they accounted holy. Then I desired that they would allow me to speak first; since if I were overcome they would be permitted to speak, whereas if they were confuted, I would be refused a hearing, and to this they consented.
