From our point of view Mohammad is not a prophet. If he can be said to be a prophet, then he is a false prophet. In my opinion, he was one of the greatest antichrists in history. I do not call him that to be “mean”, but in view of the definition of “antichrist” given by St. John, and looking back at the facts of history. I, for one, never call him “The Prophet Mohammad”, but simply “Mohammad”, not because I want to offend Muslims, but because I do not consider him to be a prophet, if he even existed.
Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son. No one who denies the Son has the Father. He who confesses the Son has the Father also.
For many deceivers have gone out into the world, men who will not acknowledge the coming of Jesus Christ in the flesh; such a one is the deceiver and the antichrist.
Needless to say, M. did not confess Jesus as the Christ. Jesus is God, who came to teach us about the Father and the Kingdom of God. There can be no “prophet” from God giving further revelation of God after Him, not M., nor Joseph Smith, because Jesus has already fully revealed Him.
