Some thoughts....
1. On the one hand, all this ME, ME, ME, ME stuff seems disconcerting. And quite unbiblical. Individualism is a factor of our Western culture (especially since the Enlightenment) but it seems to contrast with the very communal, family, US aspect we see in Scripture. God promised to lead and teach US - not just me.
2. EXPERIENCE is always a tricky thing. It's very hard to deny or denounce but also to confirm and affirm. Years ago, Dr. James Dopson wrote a book entitled "Feelings, can you trust them?" I'll save you the money and time and give you the bottom line: Nope. Feelings and experiences can come from God (insert examples from the Bible) but they JUST AS WELL can come from our sinful nature, the world and Satan himself. Dopson would say we need to TEST them (insert Bible quotes here), we need to check them out by searching Scripture and conversations with wise Christians (and I'd add, History).
3. I too made a conversion, from Roman Catholicism to conservative/confessional/traditional Lutheranism. It was a change I made reluctantly and carefully because I fundamentally asked myself what basis do I (personally) have to judge and decide? It helped that it was not a rebellion, not anything done with distain... I was and still am grateful for my upbringing in the Catholic Church, I still hold that church in esteem, I still agree with a vast majority of its teachings and practices. I didn't wander far. I simply disagreed with a few things... things I felt I was compelled to accept if I was a Confirmed, communing Catholic; I simply could not live a lie. My early embrace of Lutheranism was Catholicism minus the things I could not affirm but eventually I came to embrace Lutheranism on its own - the centrality of the Gospel, the Law/Gospel distinction, the Theology of the Cross, the crystal clear affirming of Jesus as the Savior, the fundamental humility found in Lutheran theology. But I never have repudiated Catholicism.... I hold my family (mostly Catholics) as my FULL, unseperated, entirely equal brothers and sisters in Christ and I affirm the RCC as a valid and good denomination.
4. So I suppose there is a balance here... but I put the great majority of the importance on community and history rather than my feelings or experience.
