Chris,
One more thing, do you carry a Bible with you? If not, put one in your car. When a discussion may come up referring to Scripture, say hold on a second, and go get your Bible from the car. (This is assuming you regularly read and use it and know where books of the bible are found. It would be worse to crack open a new bible and not know where anything was!)
This may seem like a superficial thing, but most Evangelicals (at least the ones you described) do not think Catholic teachings are even in the Bible. (Confession is one of my favorite to show people, next to the real presence. The Bible does not say go and teach forgiveness, which is what interpretation most Protestants put on it, but it says go and forgive.)
Another side point. Although they are probably very familiar with the Bible, there are many things they probably don’t know. Like the last verse in John telling us not everything was written down, 2 Thess 2:15 hold fast to traditions whether oral or by letter, and this one blew me away, In john 21:15-19 where Jesus asked Peter 3 times if he loved him, I had always read it as feed my sheep 3 times. I can remember doing Bible study on these verses, yet I never realized it said feed my lambs, tend my sheep, feed my sheep. 3 DIFFERENT things. I did not realize until just last week that the Bible said this! (I recognized the primacy of Peter in other ways, but this was mind blowing to me to realize I had been taught in Prostestant churches for years that it was feed my sheep. It never went farther than that. Lambs being lay people, sheep being ministers of the lambs.)
There are many things that I am coming to realize that even though I have been in the Catholic Church now for 5 years, since the majority of my studies had been in Protestant Churches, I still have much of the mindset of a Protestant. But every new thing I learn gives me such great joy. And I hope I never tire of the desire to “find it in the Bible”.
God Bless,
Maria
