I am! ...er...was?
Raised protestant for 18 years. Vaguely protestant I should say. My wife, who was raised devoutly protestant, has revealed to me how little we actually practiced our faith. At any rate I was protestant. Went to Youth Group on Wednesdays, Small Groups on Sunday, had the pastor over for parties when we were kids, I know all the contemporary Christian music sung at services, etc.
At 18 I began investigating why there are different denominations. I didn't know why there were Methodists and Lutherans and Baptists and Catholics etc. etc. So I did some research and discovered Sola Scriptura and Tradition and that explained everything. It came down, for me, to either the Eastern Orthodox or the Roman Catholic, and I thought "Orthodoxy isn't Catholic, it's ethnic, so Romans win." I can seriously remember sitting on my bed and thinking that out. So I became Roman Catholic at 19.
Fast forward five years and I was frustrated with Roman Catholicism for a variety of reasons. An Orthodox friend challenged me to find Papal Infallibility in the Early Church and suddenly I saw that the quotes I'd had before could be read differently, and that different perspective made a lot of sense. Unwillingly, at first, I left Roman Catholicism and became Orthodox. I've been Chrismated a little over a year now.
There is a huge difference, 'fellowship'-wise, between Orthodoxy and Roman Catholicism. Honestly, I didn't realize how lonely I was as a Roman. I never really thought about it. I might have been able to live that way for the rest of my life and probably would've been fine, but having now gone into a church where fellowship is such a huge part of it, I couldn't go back to not knowing a single person at my parish, having no friends who share my faith, and feeling like an island.
