Following a particular church's teachings may or may not make you a Christian, it depends on whether they lead you into a personal relationship with Christ. If they don't, then following their teachings won't make you a Christian. If your church doesn't teach that a personal relationship with Christ is what makes you a Christian, let them be accursed. To be a true Christian we must have a relationship with Christ. Some believe that being baptized makes them a Christian.
Baptism is an outward sign of an inward work.
It should always follow the beginning of a relationship with Christ. But the Bible makes it clear that baptism takes place after one has become a Christian believer. Getting wet does not make you a Christian any more than getting full of oil makes you an automobile mechanic. You do not get baptized to become a Christian, you become a Christian to get baptized. It is a relationship not a ritual that makes you a Christian.
