i haven’t read all of the responses in this thread but as the question seems to be asking for individual experiences, i don’t think it’s necessary to read them all before sharing my own.
i went to elementary school and CCD. was baptized, received first communion, and was confirmed in the catholic church. that is where my education (for a time) stopped when it came to doctrine and “what the church actually teaches”. i had a conversion experience during high school and began to live my faith more and more. i attended mass every Sunday, but it seemed so dry to me (please don’t take offense, this is my personal experience) while the protestant church i went to felt so alive. the people actually liked each other. i had great experiences with the priests and nuns at the parish i grew up in but i was so bored by mass while the protestant service was engaging. i went to mass every Sunday until i moved out of my parent’s house (that was the deal with my mom). i began to study theology more and more. i started doing student ministry. i had nothing against the catholic church (in fact, to this day i believe in transubstantiation, how this is done i might disagree with the catholic church on, but i believe Jesus is truly present in communion body, soul, divinity) but i had (and still do) the understanding that if we claim Christ as Lord according to the ancient Creeds, then we are a part of His Body (the Church). i began to do student ministry full time. i moved from the area i grew up in to a new area to head up a ministry. this ministry was inter-denominational (meaning we had supporters from many different denomination, including catholics) and i liked the feel of that. there were some supporters here who had some sort of relationship to Scott Hahn (who i had never heard of) and told me some of his story. there were some similarities between him and me so i bought Rome Sweet Home and read it. i was shocked. i had attended Scott’s wife’s father’s (catch all that?) church in college. we knew many of the same people, why was he so convinced that the catholic church was the one true church? i wrote him a letter and asked if i could speak with him. he graciously allowed me to come to his home (i was 1 1/2 hours away so not a bad drive) and pick his brain for an afternoon. i walked away from that conversation with an interest in finding the truth. he gave me a ton of books and tapes and i poured over them as well as lots of other books. it has been close to 2 years that i have been reading catholic doctrine and history. i feel i understand what the church actually teaches on many, many subjects. all that to say, i still am not completely on board with the claim that they are the one true church. i have great respect for the position of the pope (as well as the man, Benedict is an amazing thinker as was JPII) but i see all Christian churches as being part of the same body. i am still reading and searching, but as of now, i don’t see myself “swimming the Tiber” anytime soon. not because i am against the church by any means (read any of my posts and hopefully you’ll see a deep appreciation for that wing of Christianity), i am just not convinced by all the claims of the catholic church and i don’t agree with Scott’s assessment that if the catholic church isn’t what she claims to be, then she is of the devil. my mind isn’t that black and white.
