I don't consider myself a religious person (never have), and I'm glad that Al-Anon has never, in twelve years of steady attendance, presented itself to me as a religious program.
I did have a problem with hearing the word "God" in meetings early on, prob'ly 'cos while growing up in a home sick with alcoholic dysfunction, "God" was usually followed by "dammit" or worse. After awhile, as I grew, the word ceased to frighten or offend me.
As for religion vs. spirituality, I've heard that religion is for people who don't want to go to hell, while spirituality is for those of us who've already been there...
On the subject of spiritual awakenings, I don't see them as mystical happenings or anything of the sort. No lights coming down from the skies, no angels singing...
My "spiritual awakening" was simply that, through that process of having worked the Steps, my spirit (ability/willingness to participate in/enjoy my own life)--long battered and nearly comatose from alcoholism--reawakened.
That's all.
