Dr Shuu,
I don't quite understand your statement as Mohammed is supposed to be the last word on prophecy whereas the Christian churches do have further provision for prophets, that being one of the three main identifications within its leadership, Prophets, Evangelists and Teachers. Therefore the Gospel that they project has to be the same Gospel that is the power of God unto salvation. Anything else is but a false gospel and this Paul and the other disciples warned of in their letters to the churches. Without exception they all wrote that Jesus Christ is God if not directly by implication because they believed that. That believe was backed up by the prophets and by God Himself who made the very first prophecy about Jesus, the Seed, at the fall of man.
