Or, rather, it's like extending in voto to Holy Orders. None of the "character" Sacraments can be received in voto. BoDers admit that the character/seal isn't received in BoD but claim that the character is not essential to the effects of the Sacrament. But in Holy Orders, you can't have Holy Orders without the character. That's because it's essential to Holy Orders to have the priestly character. Why then wouldn't that be the case with Baptism? It's that character which makes us members of the Church and adopted children of God. Just as Holy Orders makes a man take on the persona Christi, so does Baptism, only to a lesser extent, so that God the Father recognizes as His sons, being in the image of His Son.
Interestingly, there are a growing number of Catholics (including Pfeifferites) who believe that the character IS received in bod. That original sin IS remitted, as well as the reception of justification. They say everything Baptism does, bod does equally since bod is now said to be a fully functional
aspect of Baptism. And why not? It becomes impossible to prove anything against bod being an inward sign, with all the benefits of the outward sign, if one has already accepted bod exists. After all, God can do anything and isn't tied to the sacraments, they say. Naturally, once you cross the line, anything goes. Every single warning and condemnation is redefined to explain how this works, so using Church teachings to debunk bod falls on deaf ears since bod has now become Baptism! Redefining terms is at the heart of the bod apologetic which proves to me at least, bod is modernism at its finest. This is relatively new, too. Once upon a time, bod'ers would never insist bod was a dogma, nor that the recipients get the character, or remission of sin. They sure do now.
