- If a Catechumen is baptized and has held on to heretical beliefs during their baptism, do they need to be baptized again even if they later fully repent of their wrong belief?
- When the water is poured on a person’s head, does it need to touch the scalp or some skin to be valid?
to both questions, not that I am aware of
No, once validly baptized there is never a need to be another.
The priest who does the baptism knows what is required for a valid baptism, trust he got it right.
