In my case I was brought up Episcopalian and never gave Catholicism a second thought. We knew about Catholics because an uncle had married a Catholic gal and had become a Catholic too. So, there was a small influence there, but still, in our home the Catholic Church was almost never mentioned. What we are brought up to believe is what we tend to believe. If you’re not brought up Catholic but some other Christian belief you are going to think of Catholics as just another denomination–one that you’ll never join, but no better or worse than your own. That’s how most Protestants think and who can blame them? We trust our parents and our church leaders to tell us the truth. Why would we question what they taught us?
If we hadn’t been ripped from our Episcopal Church after my dad died I may have stayed Episcopalian all my life and never have thought twice about it. I may have become rather heterodox, as many are, going more with the mainstream society’s mores than those of Christ, as many Episcopalians have. Or I may have become a Continuing Anglican, clinging to the truths the Episcopal Church once taught (that were very close to those of the Catholic Church) and even become an Anglican nun/sister–like those seen in the royal wedding.
I can only chalk up my interest in the Catholic Church to the guidance of the Holy Spirit. I came out of Pentecostalism and back into the Episcopal Church in my 30’s, but it had radically changed from my childhood. All through my life there were little incidents with the Catholic Church that, in and of themselves did nothing to convert me, but added up and paired with the way things went in my 30’s I found myself drawn to the Catholic Church, in spite of myself. The very last place I had envisioned myself was in the Catholic Church.
So, how does one learn that the Church exists and that one ought to be a part of it? Only God knows that because each person’s story is so different from each others. The only thing that seems to run, like a golden thread through all conversion stories is that the Church was there–like a castle on a hilltop. It attracted our souls and captured our hearts because the Holy Spirit put within them an ineffable desire to know and love God in the fullness of truth. It is a mystery of God that I can’t explain.
