Is Baptism Part of the Body of Christ?

We make a big distinction between doesant work versus the way it ought to be done. Some men say, i just want to make this pursel between me and my son without any witnesses. And thinks is missing part of the public declaration as well. So we call that illicit in canon law,. which means it's according to the church's rules, individuals are not allowed to do that. You can just go out and baptize on your own, because the church wants to make sure things are done right and can be witnessed to them. But if somebody still decides to do theirown thing and do it, it would still work and still be a baptism, if it was done properly
