Christians]

"If only they [i.e. Christians] had stood fast by the Law, the Gospel, and all the revelation that was sent to them from their Lord, they would have enjoyed happiness from every side. There is from among them a party on the right course, but many of them follow a course that is evil" (5:66).

"Oh People of the Book! Commit no excesses in your religion, nor say of God anything but the truth. Christ Jesus, the son of Mary, was (no more than) a messenger of God, and His Word which He bestowed on Mary, and a spirit proceeding from Him. So believe in God and His messengers. Say not, 'Trinity.' Desist! It will be better for you, for God is One God, Glory be to Him! (Far exalted is He) above having a son. To Him belong all things in the heavens and on earth. And enough is God as a Disposer of affairs" (4:171).

"The Jews call 'Uzair a son of God, and the Christians call Christ the son of God. That is but a saying from their mouth; (in this) they but imitate what the unbelievers of old used to say. God's curse be on them; how they are deluded away from the Truth! They take their priests and their anchorites to be their lords in derogation of God, and (they take as their Lord) Christ the son of Mary. Yet they were commanded to worship but One God: there is no god but He. Praise and glory to Him! (Far is He) from having the partners they associate (with Him)" (9:30-31).
