the scripture there in 1 john states that those who deny Jesus is the Christ are a liar and the anti Christ. The Quran doesn't do this:
The Quran chapter 3 verse 45: "The Angels said, "Mary, God gives you news of a Word from Him, whose name will be the Messiah, Jesus, son of Mary, who will be held in honour in this world and the next, who will be one of those brought near to God."
the Quran teaches Jesus was the Christ, the messiah and gods agent in earth through Mary. The Quran condemns the trinity, which I also agree with as I've stated elsewhere the bible does not support the trinity. A Christ is merely gods representative.
Moses was a Christ, Jesus was a Christ - and the Quran teaches this. There is a verse in another sura that even states Jesus death was a death "equal to Adam" which is a clear reference to the role he played as the messiah in repurchasing mankind.
Like I said earlier, many many times the Quran states it is not a replacement of scripture but a confirmation of it (referring to the bible). It is encouraged to read the bible and the Quran together, with one as a confirmation of the other. I have found no contradictions in the Quran, and I would submit if you appear to have found one, that the full harmony of Quranic verse would, together, dismiss it.
