“A lot of the criticism about Scritpure alone that I hear from Catholics involves the question of *How do you know you’re right and not going into error?”
All a Catholic needs to know about the Bible is contained in the Catechism of the Catholic Church. Simply layed out.
Protestants have a thousand and one different study bibles with a thousand and one different “experts” telling you what it really means (a thousand and one different interpretations).
That isn’t the case at all. First, you know the Scripture yourself very, very well, and you’re depending on the Lord to help you understand it. And second, there are reasonable differences in interpretation and out-and-out heresy. Differences on baptism are one thing, but saying Jesus really didn’t perform a miracle where the Bible said he did is another. And what any difference means in a certain, situation, the Lord will reveal it to you at the time. If you’re talking at different times to two mainline Protestants who doubt Jesus was ever really resurrected, and one is a confused, drug-addicted teenager and the other a pastor of a church, what you focus on won’t be the same.
