By the time I was 19, I was drifting away from all that, and I guess by 23 I was calling myself a "retired Catholic", leaning toward agnostic. Most of my siblings left a bit earlier, I think. 

Catholic brainwashing is a very effective procedure though, and runs deep into the spine. There are certain hardwired feelings and reactions that just won't go away, no matter how hard you chip at them. Other former Catholics know what I mean. Catholic flavored Guilt is one; practically unnoticeable while you are a Catholic, quite annoying later on. So I have finally found a better term -- I no longer call myself a "retired Catholic", I prefer the term "recovering Cathoholic". 

I have had brushes with many other religions since even before I started drifting out of the Church, mostly because my parents had tons of books on every subject strewn throughout the house. Nothing was censored; if you were able to read you could pick up anything from The Cat in the Hat to The Joy of Sex. Some of my favorite religions (or philosophies) were the pantheons of Greece, Rome, and Norway; Taoism for it's simple purity and celebration of Change; the mostly unknown nature worshipping rituals of Wiccans and Druids (though some of those druidic rituals were pretty bloody); and (still fading in history) magical practices of Pennsylvania-Dutch Pow Wow and American Indian Shamanism. 

I then reached a period, after experimenting with all sorts of "supernatural activities" and not getting anything conclusive (that is, getting lots of results, but nothing that I could pin "supernatural" on), where I finally decided wholeheartedly that this religion thing was ridiculous. I then coined the term "Apatheism" to distinguish myself from Those Who Don't Know (Agnostics), and Those Who Don't Believe (Atheists). I was a member of Those Who Don't Care If God Exists. This lasted for at least a few years. 

But eventually I was forced to admit that I'm just a Wannabe Apatheist. I am fascinated not only with all sorts of religions, but also with the idea of a god. I haven't come up with a word for it yet, but my current belief statement is something like: "I don't believe in a god, but I wouldn't be at all surprised if I discovered I'm wrong." Experiences like meeting Odin make me wonder sometimes (cynically, yet still I can wonder). Of course, not believing in a god doesn't keep me from having a religion. 

As far as social religions¹ (sometimes called organized religions, or cults) go, these days I am just amused. Discordianism has great appeal to me because it takes religious silliness² to a new level. Same with Subgenius, but to a lesser extent, because that's just a spoof on Scientology, whereas Discordianism is a religion in its own rite, so to speak. 

Also, I've been trying to push Ginamaism, the worship of the lovely goddess-on-earth Gina, but that hasn't caused any great Jihad or made us a lot of money yet, so obviously I'm not trying hard enough. 

Now, as for real religion: It seems to me that people make connections between themselves and the rest of reality or parts thereof, and when they can't explain the intense strength of a connection, they call it "spiritual". To that end, I have certain connections that have been here my whole life, strong enough for me to say they are spiritual. I have no doubt that these very strong spiritual connections will stay with me the rest of my life, without possibility of a change of mind. If true religion goes no further than personal spirituality, I would have to say that mine is in the Trees. 

I am spiritually connected with trees and forests in such ways that some might call me crazy. There have been times that I swear trees seem to whisper to me, and there have been plenty of times that I have spoken back, just in case. Sometimes, when people ask me what my religion is, I say (if I don't have time for a rant like right now), "Climbing Trees." It is a very pleasant, personal religion, impossible to pass on to others because such tree-born experiences and feelings will never be the same as anyone else's³. It has nothing to do with Druidism, whatever that is. I guess if I had to classify it, I'd say it's in there with aboriginal nature-worship religions. It has lasted my entire life and is part of my earliest memories. I have swung from trees and climbed them, and even slept in them. Trees are neural connections to the rest of my universe. 

1. Cult is to spirituality as ethics is to morality. The latter (spirituality, morality) are more important and more meaningful to the individual, while the former (cult, ethics) are more important to groups of people. Cults and ethics are thrust upon each person by groups of people, not to provide meaning to those people's lives, rather to establish control.
2. The word "silly" actually comes from the Middle English "silli", meaning "blessed". Now all of you stodgy god-squad stuffy types can't tell me that silliness isn't important in a religion. Hail Eris, ramadamadingdong, etc.
3. I have learned recently that there are certain aspects of the Shinto religion that resemble my type of nature worship. Of course as a cult, Shinto also has beliefs that don't come close to mine whatsoever.

Here is where I'll put other thoughts re: ligion and other metaphilosophies I had while discussing this subject with people via email and all, as I accumulate them. Anywise, the above article is a snapshot of where I was at the moment I wrote it.  I certainly leave room in my life for changing my mind, or even admitting  I'm wrong. Except about the trees of course. :-)
