Pretty important Sacrament. All other Sacraments flow from this one. Baptism saves you.Looks like too much mess being made out of something so easy as getting dunked in water. I've never read any scripture that says without getting dunked a person is in trouble. According to some it sounds like its not just that but even the dunking has to be "correct"
This is legalism. It's not Christianity.
Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a clear conscience, through the resurrection of Jesus Christ, 22 who has gone into heaven and is at the right hand of God, with angels, authorities, and powers subject to him."
