I'm a Catholic.
I was born a Catholic, baptised a Catholic, got my first confession, first Holy Communion, and Confirmation. I was married in the Catholic Church. I will likely spend my whole life considering myself a Catholic.
My wife (who is not a Catholic, but not really anything specifically else), has asked me about my religion, and I admit that I do not feel that I have fully reconciled my religious beliefs with myself, or anyone else. Here in the USA take a decidedly different approach to religion than much of the rest of the world. In many countries, a specific religion is part of the culture. While Christianity predominates here in the USA, we have dozens, maybe hundreds of different variations on Christianity. We also have a large Jewish population, a good smattering of your Eastern religions, atheists, etc. We're a melting pot. So, it seems to me like we treat religion with the same democratic bent that we treat politics with.
My Catholicism comes from my Italian heritage. That heritage is important to me- there's a lot that I appreciate within. But in conjunction with that, somehow blended in, is this very American aspect to religion that allows me to disagree with the Catholic Church on some issues. The biggest issue I have with the Church is that my wife, who I love, and who was allowed to marry me within the Church, is not allowed to receive communion when I do. I know it also bothers her, too. I understand the Catholic Church's stance here, but I do not agree with it.
Will this cause me to abandon the Church? No. Will it cause us to attend Mass less frequently? Absolutely. We show our faces inside a Church about 3 to 4 times per year. I enjoy Mass, and if the priest is good, I have gotten a lot out of it. When I was younger, my parents took us to Mass EVERY Sunday. I went to Catholic grade school, and a Jesuit HIgh School. I like my faith. I just don't practice it. But apart from some of my differences with organized religion (and I do have issues with more than just the Catholic Church; living in the South I've got all sorts of reasons to avoid religion) I just don't feel that the benefit is there for me- and certainly not for my wife, who feels uncomfortable and left out. I consider myself a fairly moral person, I like to think I was raised right and had good values instilled in me, and I can make decisions using those tools that are right and just.
I just realized, this debate isn't really about religion. It's about God. Funny that the two are inseparable in our minds this way. But I realize that everyone gets to where they are in their life in a unique way. Where I am is basically this: I can't prove there is a God, and I can't prove there isn't, but when I look around, and just see the power of everything that's in existence, I just can't for even a second believe that there isn't a divine force behind it all.
Plus, I realized that if I were God, I'd probably be awful lonely, bored, and anxious to do stuff. Creating a universe and a bunch of planets and some life would be pretty cool. Oh yeah, that's right. I think God's an engineer, a geek, and a nerd. So there's you're Trinity. ;-)
