Well, I can’t say that about all Catholics, because I’ve never met them all :) No denomination owns the “fail to read the bible” label, because many of us fall short in that category. That being said, I usually encounter surprise by the Catholics I’ve interacted with when I show them from scripture what I believe and why I believe it, namely justification by faith as Paul taught it in Romans. What role do the sacraments play in our justification? I’m confident that Paul would say nothing.
23For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, 24and when he had given thanks, he broke it and said, "This is my body, which is for you; do this in remembrance of me." 25In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me." 26For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes.
27Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. 28A man ought to examine himself before he eats of the bread and drinks of the cup. 29For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself. 30That is why many among you are weak and sick, and a number of you have fallen asleep.
