Among them the few Christians who were scattered here and there throughout Arabia were of least moment. Split asunder as they were into various warring sects--the Monothelites, Jacobites, Melchites and Nestorians--they worried the Prophet but little; he seems to have regarded them with a tolerant and mildly amused eye. Having had scanty intercourse with them, he was probably quite ignorant of their disputatious creeds; therefore, while the Koran always speaks respectfully of the Saviour, Who is invariably designated “Jesus, Son of Mary,” it makes many deplorable errors when it discusses the tenets and theogony of Christianity. It expressly denies that Jesus is the Son of God and completely repudiates the established doctrine of the Holy Trinity: “Wherefore believe in God, and in the Apostles; and say not, _There are Three_. Refrain: it will be better for you. Verily the Lord is one God. Glory be to Him! far be it from Him, that there should be to Him a Son.” And Mohammed seems to have made the even more egregious error of supposing that the Trinity which he condemned was composed of the Father, Jesus and Mary; for the Koran utterly fails to recognize the incontrovertible existence of the Holy Ghost. Thus, while it has been reasonably urged that the Prophet both comprehended and hated Roman Catholicism, it may just as plausibly be argued that the conception of the Holy Spirit as a separate and distinct entity was too subtle for his eminently practical mind to grasp. With Judaism, however, the case was very different. Though the Koran might place Christ on par with Abraham, Moses, David and other Hebrew prophets, it was to the customs and rites of the Jews that Mohammed paid obeisance rather than to those that had clustered around Christianity. Scarcely had he taken up his residence in Medina when he deliberately humbled himself in an effort to placate and win over the Jews; for, knowing their numbers and their power, he strongly desired to enter into a lasting union with them. To that end, he bound himself and his adherents to the Jews in a contract whose obligations were relatively mutual: “The Jews will profess their religion, the Moslems theirs.... No one shall go forth to war excepting with the permission of Mohammed; but this shall not hinder any from seeking lawful revenge.... If attacked, each shall come to the assistance of the other.... War and Peace shall be made in common.” There is also every reason to suppose that the command promulgated by Allah, when the Prophet visited Him in the Seventh Heaven, to the effect that all loyal Moslems must henceforth direct their prayers five times daily toward Jerusalem, was given because Mohammed expected that the Jews, seeing the Moslems thus busily engaged, would be insidiously flattered and insensibly led to look favorably upon Islam. Nor did his efforts stop here. The period of fasting which he had decreed for the Moslems coincided
