They most certainly did. They accepted the books that say they should smear fish guts on their eyes, they should burn fish livers to scare away demons, and that having baby girls is a bad thing. That still doesn't say they have the authority to do it. They just do it anyway. They also add paganism even though God said not to. So it looks like the Catholic Church really doesn't care what God says.
If the Catholic Church disregarded God, they would not have been around for 2,000+ years and still going strong.
