Just because they loosely use the name of Jesus the Christ does not make them christians, same goes for muslims (Jesus is a prophet to them), catholics and jehova's witnesses and even some new branches have now shown their true color of doing what they want and intentionally disobeying God's word to adjust to society's changes like the United Church of Christ, the Episcopal Church, the Evangelical Lutheran Church in America, and Methodist church. Schriptures did mentioned as the end of days is near many false prophets will appear to mislead the people.
