The reason for why I left the faith so many years ago (but am now being called back) is really difficult to answer.
My parents married in the 1960s, both brought up in Catholic households, when they were 20. They were divorced in 1972, when I was three years old. I was baptised Catholic and I had a very devout grandmother who did all she could to keep me in the faith, ensuring my first communion, CCD classes, etc.
This was California in the 70s. My mother rejected Catholocism due to the guilt and shame factors and embraced “alternative” religions (ie transindental (sp?)l meditation, buddhism). My father fell away from the church after the divorce, never to return. He is on his 4th marriage.
So I did my best, trying to keep the faith. But with role models like those, I feel like I didn’t really stand a chance. I went to a very modern church with my grandmother (altar in the center, folk mass and the like) and I never liked it. I had attended Latin Mass as a young child and I missed the ceremony and reverance. God was never spoken of in my house.
College. Questioning. Reading up on Egyptian mythology and Osiris and Hercules, both supposedly born of virgins and resurrecting. I believed Christianity to be a sham, so disenchanted.
And there are doctrines I still cannot fully embrace. I am not sure there is a Hell. I believe in ghosts. I believe in birth control, and I really hope my dog goes to heaven

. Seriously though, I am split between faith and reason. I feel some of the teachings of the church are based on how powerful the church could make itself and not necessarily the true word of God.
But in the last year, I have been called back. And people on this forum have been praying for me, and it means so much. I cannpt truly call myself a Catholic, because I would be of the cafeteria variety and I would not disrepect the church like that. But deep down, I know I am Catholic. I am a baptised Catholic. I am trying to find my way back. It is hard, but I hear God calling me home.
