No, because I did the same thing. I went through catachism, which is just an educational program that teaches the principles Catholicism to members of the church who are in public school, from first grade until tenth grade. That was the year I was supposed to get confirmed, but I dropped out mainly because anytime I would ask a theological question, they would say that I couldn't ask those kinds of questions until I was confirmed. After that I sort of became an agnostic. I believed that there was some all powerful being that controlled everything, but I wasn't sure it was God that I had been told existed. It wasn't until about 4 to 5 months ago that I put my trust in Jesus Christ again, not that I ever had before though. So, now I'm just a Christian. However, I am looking into the Methodist church.
Whoever told you that was an idiot and were just covering up for the fact that they didn't know the answers.
