675 Just as a foolish servant may go wrong by excess of zeal for his master, so in religion people's excesses may lead them to blasphemy or a spirit the very opposite of religion. The Jewish excesses in the direction of formalism, racialism, exclusiveness, and rejection of Christ Jesus have been denounced in many places. Here the Christian attitude is condemned, which raises Jesus to an equality with Allah; in some cases venerates Mary almost to idolatry; attributes a physical son to Allah; and invents the doctrine of the Trinity, opposed to all reason, which according to the Athanasian Creed, unless a man believes, he is doomed to hell forever. Let our Muslims also beware lest they fall into excesses either in doctrine or in formalism, (Cf. 11:110).
676 Christ's attributes are mentioned: (1) that he was the son of a woman, Mary, and therefore a man; (2) but a messenger, a man with a mission from Allah, and therefore entitled to honour; (3) a Word bestowed on Mary, for he was created by Allah's word "Be" (kun), and he was; 3:59; (4) a spirit proceeding from Allah, but not Allah: his life and his mission were more limited than in the case of some other Messengers, though we must pay equal honour to him as a Prophet of Allah. The doctrines of Trinity, equality with Allah, and sonship, are repudiated as blasphemies. Allah is independent of all needs and has no need of a son to manage His affairs. The Gospel of John (whoever wrote it) has put in a great deal of Alexandrian and Gnostic mysticism round the doctrine of the Word (Greek, Logos), but it is simply explained here. (R).

48 The Jews are warned against denying Jesus as the Messiah, while Christians are warned against calling Jesus Allah.
