Most parishes in my area charge $100 for ocia courses but the one closest to me charges $250, money and transportation is an issue for me but I’ve already committed and paid to do ocia at the other parish while attending mass at the one closest to me. I don’t mind having to do that for my faith but this still seems unfair for anyone in the future. Is this something I should contact my diocese about or is this normal?
