Vows of chastity and obedience are voluntary. There are anglican nuns who I assume take vows of chastity. Chastity is different than celibacy. It’s a discipline, like fasting. As a mother of three and grandmother of one I can tell you that my prayer life when I was raising them was not as rich as it is now. A practicing Catholic if he were to be a priest and be married would practice NFP which while effective, usually results in relatively large families. Not a lot of time to minister to his flock. Our priest probably works an 80 hour a week. On holiday weeks I’m sure its longer. He routinely gets up in the middle of the night and goes to visit the sick and dying. He’s known for that.
Thank you for the education!
