Probably no one issue has contributed to more confusion, fighting, and divisions in Christendom than baptism.
Some churches teach baptism is a sacrament, some that it is necessary for salvation.
Some teach immersion, some pouring, some sprinkling. Apart from baptism, some churches do not consider you a Christian and some will not let you join the church or teach in the church. What one believes about baptism has a large influence in determining one's church or denomination. In order to try and remedy this confusion, it is necessary to see what the Scriptures teach about baptism. Homer used it of a brazier who dipped hot brass in water to temper it.
