From YT: You'll be surprised to find out what qualifies as a fish that can be eaten for Lent. What an indulgence! Who does this make reconciliation with? This is evidence that God isn't even considered in these decisions 'cause these would be on His list as an "unclean" meat. So when you "give it up for God", it's not an acceptable sacrifice to Him, just like Cain's wasn't accepted.
Gregory is the same pope that made the proclamation that Mary Magdalene was a prostitute in order to take authority and honor away from her. Now how do you think Jesus would feel about that?
