My suggestion Raptor is if you do like these people and want to "branch out" a bit socially, check them out. From what I know of Baptists, they are a VERY musical bunch. You'll hear louder and more joyously heartfelt songs of praise there than you ever did at our mutual religious alma mater (the RC Church). I really doubt going to a Baptist church could harm you in any way -- might even prove helpful!
Organized religions are social institutions, not spiritual ones though. I don't think there's any such thing as a "spiritual institution". Spirituality is a highly subjective, PERSONAL experience. Religions can only take you so far, spiritually. The preachy dogmas, "catechisms" and exclusivism found in most organized religions can really stifle spiritual growth.
So, if you want to go farther, you're on your own, bud! At least, that's my experience to date ....
