The point I was somewhat clumsily trying to make was that there was no requirement for Meghan to do anything at all. I thought it spoke volumes that she made that choice to spend the time with the Archbishop in preparation classes for both her Baptism and Confirmation.
It seems to me more like a choice of faith rather than the prevalent attitude of just "getting the baby done" and having a big Christening event as both her baptism and confirmation were done privately with only Harry and her future Mother and Father-in-law as witnesses.
