Yes, but it does not hurt to caution on the side of being safe. If you are going to do it, you might as well try to follow the Bible the best you can.
True enough. As long as we don't fall into the same trap as the Pharisees. Baptism -- of whatever form -- is more than anything else a public declaration of faith, and that's an immensely important step in joining the Body of Christ.
However, to stomp around declaring that only certain styles of baptism will work ... well, the Pharisees said such things too, and were wrong.
