Let us LIVE the Catholic life. Let us not hide our Light under a bushel basket! Do your penances in private - but when someone asks you about why you're not eating meat on Friday, gently explain to them that you do this in honor of Good Friday - and everytime you would have partaken in meat - it's a reminder to you of Christ's Ultimate Sacrifice in our behalf. I know most of us do this year-round, but during this time of year more attention is drawn to the Catholic "meatless Fridays."
After Lent is over, we can continue to use this as a witness to our fellow Catholics who might tell us, "Lent is over, you don't have to continue with abstinence from meat on Fridays..." and then you can (gently and charitably) remind them that the requirement of penance on Fridays is STILL a requirement for EVERY Catholic - even so-called Novus Ordo Catholics! We don't HAVE to continue observing the abstinence from meat, but it MUST be "something equivalent." If it has to be equivalent, why not just stick with meat?! Meatless Fridays and Friday Fish Fries used to be one of our identifying marks on our communities! It should be again. Encourage all Catholics to continue meatless Fridays year-round, unless a solemnity falls on a Friday.
