I quit religion when I was 8.
I was forced to go to catechism (CCD) every Monday after school and I guess i was annoying the nun with all kinds of questions. She called in the priest who squeezed my face in his bony fingers and got right up in my grill and yelled, "You are not here to ask questions! You are here to listen and believe!"
I started skipping Monday CCD the very next week and haven't been in a church since.
As far as believing; I do not believe the god that the bible tells of exists.
If there is a supreme being then I have yet to see evidence proving that existence.
It wasn't a Catholic, but a Presbyterian who essentially said to me, "You are not here to ask questions! You are here to listen and believe!"
I was 10. I really liked the missionary family that brought me to the place; every now and again we exchange a letter or two, or catch up on the phone. But back then, even to my 10 year old mind, the shit taught by the Church-Lady-freak-shows in Sunday School was ******* bananas; and the questions that my 10 year old mind presented to them apparently revealed some embarrassing truths about their beliefs--too embarrassing to allow the churchers to be understanding, patient or welcoming.
What they, and frankly every single (alleged) "Christian" I've encountered since (including those here), have managed to validate for me is their God is a vain, sadistic, bloodthirsty God; that their God is the God of human suffering and misery.
I reject their God of torture and human misery on moral grounds. I refuse to validate the authority of a being who (allegedly) created imperfect volitionals to worship him, and then refuses to accept responsibility for the predictable consequences of such imperfection in his creation, so that he can rationalize justifications to inflict eternal suffering on those who (predictably) are imperfect "believers."
AND I SWEAR, if you offer me salvation through the blood of the Lord, Jesus Christ(TM), I'll say "NO THANK YOU" to this offer to expunge my "sins" in the blood of an innocent, nor shall I place upon him the burdens of "sins" he has not committed. In other words, I refuse to make a sacrificial animal of any human being -- including Jesus.
So, while the God of misery is certainly my enemy, Jesus is all-right with me; and I'm pretty certain that I'm all-right with Jesus.
