"But suppose we admit - as the followers of the Koran claim - ([a claim] whose denial all the wise and zealous believe, as was made evident above) - that the goal and intent of the book of the Koran, is not only not to detract from God the creator or from Christ or from God's prophets and envoys or from the divine books of the Testament, the Psalter, and the Gospel, but also to give glory to God the Creator, to praise and bear witness to Christ (the son of the Virgin Mary) above all prophets, and to confirm and approve of the Testament and the Gospel. [If so,] then when one reads the Koran with this understanding, assuredly some fruit can be elicited [from it]."
