I understand that when people go to confessional in the Catholic Church, the priest will often prescribe certain things for them to do for penance in order for their sins to be forgiven.
I have heard people in passing mention doing "Hail Mary's", and I'm pretty sure they weren't talking about long desperation passes at the end of a football game. I've also heard mention of "Our Father's". I assume these refer to a prayer to Mary and recitation of the Lord's Prayer.
So, are these the most common thing a priest will prescribe? Are there any others? Fasting? Is there a set pattern prescribed by the Catholic Church?
