“The chasm [between Islam and Christianity] cannot be bridged by rickety planks of compromise. Syncretism would be equivalent to surrender; for Islam thrives only by its denial of the authority of the Scriptures, the Deity of our Lord, the blessedness of the Holy Trinity, the cruciality and significance of the Cross, (nay, its very historicity) and the pre-eminence of Jesus Christ as King and Saviour. And this denial is accompanied by the assertion of the authority of another book, the Koran, the eclipse of Christ’s glory by another prophet, even Mohammed, and the substitution of another path to holiness and forgiveness than the way of the Cross. These denials and assertions are imbedded in the Koran and are the orthodox belief of ninety percent of the people. On every one of these points the true Moslem stands arrayed in armor against the missionary and the Truth, of which he is the custodian and preacher.” (Samuel Zwemer, “The Chasm” The Moslem World, vol. IX, no. 2/April 1919, pp. 112-113)
