The USCCB requires Catholics in the United States to do penance on Friday throughout the year, not just during Lent. Abstinence from meat is a recommended penance, but other types of penance can be substituted. The CCCB similarly instructs our Canadian compadres.. I'm ashamed to say that I had never heard of this requirement until recently. I was under the impression that abstinence on Fridays was done away with by the Second Vatican Council. Tomorrow, we will have an opportunity to offer penance in union with Christ and in obedience to the Church. Let's take that opportunity.
