I would like to offer a word...
I was raised Protestant. (Presbyterian.) I attended a Presbyterian church with my grandparents up thru early high school. Most of the time that I was there, I did not have any interest in learning about the differences between the various Christian denominations/churches. In fact, I specifically went out of my way
not to learn because I didn't want to know; I just wanted to consider myself non-denominational.
In senior high school, however, that changed. It's a long story why and I won't go into it. Suffice it to say I became deeply disturbed at the divisions in the church and decided I felt like learning where they came from. I began to exhaustively study church history and in doing so became interested in Catholicism. I signed up for adult conversion (RCIA) classes at a local Catholic parish. I attended them for a year and was received into the Catholic Church the following Easter.
I was not Catholic for long, however, before I started to question whether I'd done the wrong thing. I still had a lot of Protestant friends and family who were
not very welcoming of my conversion. Please understand, while most Protestants are generally not terribly fond of Catholicism, the Presbyterian church I came from was particularly anti-Catholic. Night and day they filled my head with worries that I may jeopardize my salvation if I persisted as a Catholic because I was following the anti-Christ in the Pope.
This became a serious issue as eventually I started to sink into depression and lost sleep because of it. I spent 100% of my free time for a couple of years reading theology trying to figure out which side was right, Protestants or Catholics. I must have done an entire Theology degree's worth of research on it. You wanna know what I concluded? NOTHING. I could never come to an answer. I felt there were good arguments on both sides of the fence. (For example, are we saved by faith alone or faith plus works? Romans 3:28: "For we maintain that a man is justified by faith apart from works of the law." James 2:24: "So you see that a man is justified by what he does, and not by faith alone." The Protestant will point to the former and contextualize away the latter. The Catholic will point to the latter, and contextualize away the former.) The only thing that all this struggle DID do: it separated me from my simple, humble relationship with Christ Jesus. It ruined my life. The joy and peace of my salvation was long gone and forgotten. I spent far less time praising God in prayer and thanking him for my life, than I did begging for help with my "problem".
The only way I eventually resolved the conflict was by deciding not to decide. I began following my then-girlfriend (now my wife) to her Lutheran church (ELCA) one Sunday and I was happy with what I found there. I found a worship service I liked, people who were friendly, and pastors who faithfully preached the gospel. That was about 8 years ago. That church is where you'll still find me on Sundays to this day. I joined the ELCA about a week before our wedding. We married in that church, and I'm now a lay-leader there.
I don't consider myself a Lutheran. I don't consider myself a Catholic. I don't consider myself a Protestant. I don't consider myself non-denominational. I only want people to look at me and see a follower of Jesus. Whatever other labels they choose to place upon me, I don't care.
I don't want to discourage anyone from exploring the issue, certainly not. Most people are not as obsessive-compulsive as I am and would probably not carry the search to such an extreme.
But the moral of my story is only to point out that the church we go to does not matter nearly as much as the One we worship while we are there. And I believe he's there in Catholic churches as well as Protestant. (And Orthodox!) Remember how Paul warned us not to side with one Christian leader over another. (1 Corinthians 1:10-17) Likewise Jesus prayed that we be one as a sign of his presence among us. (John 17:22-23) Maybe for most of us that do not have a PhD in Theology, we'd be better served finding a local parish church where we feel comfortable, and settling down there, regardless of denominational affiliation... maybe, maybe not. Just a thought.
Peace
