@UncouthYouth Technically no, as a national bishops conference isn't the magisterium. But if your particular bishop commands you to do something, then in most circumstances you must do it.
@OpStCyprian "nothing may be made mandatory on believers which is not mandated by Scripture"
Mark 7 nowhere says that. It says nothing further than that nothing may contradict Scripture.
Just because someone can make something valid logically (it’s either in A or A & B) doesn’t mean the Catholics actually know how any specific teaching is grounded. We have absolute certainty it’s somewhere in there! It’s logically valid! The bait & switch of Roman polemics.
A trolley problem for the abortion issue:
In a burning building there is a newborn baby in one room and 5 frozen embryos in another room. You only have time to get to 1 room.
Which would you save?
