In high school, all of my religious questions were shelved. I was uncertain of my faith, uncertain of God, and enamored of science. I had friends who were Catholic and I remember them talking about Confirmation classes, and Lent and fasting before Holy Communion. I became peripherally aware of various Catholic practices.
Sometime around my high school graduation my mother introduced me to two different series of novels by Fr. Andrew Greeley. Let me be very clear: I do not recommend these. Fr. Greeley has an agenda. He's right about a great many things, and wrong about a few, and his novels have the potential to give scandal. I saw this agenda and said, "Hello agenda. I do not agree with you, agenda. Goodbye, agenda," and went on my merry way. So why do I mention these novels which I do not recommend? They were, for me, a first glimpse into the Catholic world. These novels were the first edges of the beginning of an answer to the question, "What does it mean to be Catholic?"
