May I encourage you to read Rod Dreher’s account of his conversion from Catholicism to Orthodoxy? It’s not important as relates to denomination, rather it is a well-written account of coming into the light of Christ after a season in the desert. What is most remarkable, however, is how Mr. Dreher acknowledges his own responsibility for abandoning Catholicism even as he examines the disappointment and disillusionment he suffered at the hands of his Church. But here is the heart of the matter:
I had made in my life till that point the fundamental error of conceiving of the Church as an end in itself, rather than a means to the end of becoming a saint in Christ.
I’ve made this mistake and often. It is so easy to stare at the altar and see only the sins of the people who serve at it. Humans have a funny way of failing to live up to one’s expectations. But that’s exactly why we need to focus on Christ, instead.
