On this a person of Alexandria, who was present, requested of the kadi that these men might be sent for, since they were learned men, versant in the scriptures, and it would be right to dispute with them concerning the faith.  Our friars were accordingly sent for, and, leaving Peter to take charge of their goods, the other three went to the kadi; who began to dispute with them concerning our faith, saying, “That Christ was a mere man, and not God.”  But friar Thomas[2] shewed evidently, both from reason and by examples drawn from Scripture, that Christ was really God and man, and so confounded the kadi and the other infidels, that they were unable to produce any rational arguments in contradiction to him.  On this some one exclaimed, “And what do you say concerning Mahomet?” To this friar Thomas replied; “Since I have proved to you that Christ is really God and man, who hath given the law to mankind, and since Mahomet set himself contrary thereto, and taught an opposite law, if ye are wise, you may well know what ought to be concluded respecting him.”  But the kadi and the other Saracens insisted that he should declare his own opinion concerning Mahomet.  “You may all see,” said he, “what must be my opinion; and as you insist that I should speak out plainly, I must declare that your Mahomet is the son of perdition, and is in hell with his father the devil.  And not him only, but all who have held his law, which is entirely abominable and false, contrary to GOD, and adverse to the salvation of souls.”  On hearing this, the Saracens cried out, “Let him die! let him die! who hath thus blasphemed against the prophet.”
