Some Bishops regularly dispense for St Patrick’s Day, when it falls on a Friday, during Lent. Some do so for St Joseph.
They certainly have the “right” to do it. And with all that is going on in the world, I can see their point.
We still have plenty of eggs and pasta. So we can easily avoid meat. But many people don’t. And if they are like me, they aren’t going out, at all.
Additionally, for instance, my husband (who isn’t Catholic and doesn’t have to follow meat free Fridays) is working second shift. He normally comes home for lunch when working his normal day shift. I can make something meat free for him and it isn’t a big deal. Now, he packs something quick and easy. Generally leftovers. Yes, there are some options. But eating meat would be much easier for all of us.
