Re: Lent Rules on Sunday?
It's up to you. You make your own rules on voluntary penances. If you want to give yourself a break on Sunday, you may do so. If you want to maintain your penances for all of Lent, then do so. The Sundays of Lent are a part of Lent and the voluntary penances that you choose for yourself are a matter of your free choice.
