No, its not even remotely difficult at all, there will be some Catholics who probably get it, I was a once a Catholic and I never said a prayer to Mary, never purchased an indulgence, ect ect. You are overthinking things it seems, if you are a catholic and you pray exclusively to God/Jesus and ignore all of the paganism, you could very well be alright, and again this is based upon all being true, and not just superstition. However, when you start adding in the pagan idolatry, which is exactly what 85% of Roman Catholicism is, exactly what Mary worship is, what praying to so-called saints is, purchasing indulgences, referring to a man as Father, ect ect, you have fully departed from the Christian faith.
If you have issues with these things, take them up with God/Jesus, these are not my opinions on Catholic paganism, go right to the source and read it for self! There is one way to God and one way only, and it is not praying to a "queen of heaven," saints, angels, statues, or buying early outs from mini-hell for self, family, or friends, there is only the one way. Literally speaking, everything else the catholic church is selling is not gonna get you to that one way, don't take my word for it, go read the bible, the vast vast majority of you never ever do, or more likely you cherry pick from it. I did the same exact thing, it often made my head swim. What I am telling you, is there very well are good people involved in Catholicism, and more than a few of them could be saved, but those few are not praying to the queen of heaven, there is no queen of heaven....
