Today, my little brother asked me for some apologetics advice, and we ended up reading some of Peter Kreeft's writings.

If you've never read this, then go read it now!

My favorite passage is:

When I was at Calvin College and investigating things Catholic and falling in love with them and feeling guilty about it, because this was the wrong church, I took a course in church history to try to get things clear.  And the very first day of the course, the wise-old professor said, “What is the Church?”  And we were all just freshman, we didn’t know for nothing so nobody answered.  So he said, “Well, you’re going to meet a Roman Catholic someday and he’s going to say, ‘You’re in the wrong church!  You’re a Calvinist, you’re in the church John Calvin founded 500 years ago.  We’re in the church Jesus Christ founded 2000 years ago.’  What do you say to him?”  Nobody had an answer.  I said to myself, “I’m in the right class.” He said, “Well, here’s what the Catholics will say: the church today is a great big thing and it looks very different from the simple thing you read about in the New Testament, but it’s the same just as that oak tree is the same organism as that little acorn.  What’s wrong with that picture?  The Catholic will say that Luther and Calvin broke off some branches of the church because it was really rotten and they tried to start a new one, but that can’t be done cause there’s only one Jesus.  And therefore, only one church.  What’s your answer to that?  What’s wrong with that picture?”  And nobody had an answer.  I said to myself, “I’m in the right class!” And he said, “Well, here’s what’s wrong with that pictures, here’s what happened: Jesus founded one church indeed and it is the church described in the New Testament, and it’s like Noah’s Ark, and it did get rotten, and Luther and Calvin and Knox and others said, ‘Gee, this Ark is sinking!  We gotta scrape the barnacles off!’  So they scraped the barnacles off and restored it to its simple, pure, primitive, New Testament essence.  So we’re in the right church!  It’s the Catholics who are the upstarts.  They’re the ones who added all those pagan barnacles.”  I said, “Oh that makes me feel good.”  I remember asking a question, I said, “Professor, do you mean to tell me that, if my Catholic neighbor and I both found a time machine and went back to the first century,”  I still remember his look, “What’s this guy, a weirdo?  Science fiction?”  “…and worshipped together, that I as a Protestant would feel more at home in that church than he as a Catholic would?”  And then he smiled.  He said, “That’s exactly what I’m saying.”  I said to myself, “Good, that means that I don’t have to be a great theologian to figure out who’s right.  All I have to do is read the Church Fathers to prove to myself that they were all Calvinists.”  Well, I read the Church Fathers and proved to myself they were all Catholics, so that’s why I’m here.

I figured I would share that with you in case you've never read it. I'm praying for you!
