The problem is that the opponent of infant baptism (Baptists, fundamentalists, and Evangelicals) will say that John the Baptist had no need for Baptism, since he was Sanctified by Jesus directly (as they deny Baptismal Regeneration.)
You might argue that he was sanctified as an infant of course, but they will show that it did not require any baptism.
Hmm. I see. You’re right of course. It’s too bad they don’t recognize that it’s a matter of semantics. “Baptism,” meaning immersion, is a symbol of death, harking back to the Flood, is an immersion into the death of Christ so as to be reborn in Him. The formula used in Baptism to validate it is just the ordinary form(ula). We are all baptized by Jesus, of course, but through intermediaries: His faithful. This is likewise the case of John, who received his baptism at the sound of Mary’s greeting.
