"Mormons DO believe Jesus is a member of the Godhead" but not that Jesus Christ is God, as the Bible states (Isaiah 9:6 "And His name shall be called Wonderful, Counselor, the Mighty God, the Everlasting Father, the Prince of Peace.") One ought not call oneself a Christian if he denies the diety of Jesus Christ. You can call yourself a Christian but that doesn't make you one. Giving Jesus all the glory due His Name will make you a Christian. Jesus said "I and the Father are one" (John 5:18) - not one in purpose, but one. Jesus is God manifest in the flesh, not a lesser being.
