I thought I would take a shot at it as well.
I am Catholic because I’ve been blessed to have thousands of ancestors over the centuries pass the baton of faith to me. A baton that was, at different times, shining, battered, tear-laden, and glorious, from people who were saintly, sinful, persecuted, and determined. I received that baton-gift and felt compelled (if only because it was the 70's) to examine it closely and eventually reject it. I returned after sitting in church one day, sad and confused, where I heard an almost audible voice say from the crucifix, "This is My Church."
Despite years of serious efforts to convince me otherwise, including the horrendous abuse scandals, I have clung to this gift and done my best to pass the baton to the next generation. I encouraged my children, as they did their own questioning, to analyze the world views from which they could choose. Look carefully at their families – after two or more generations raised with a particular ism. Look at their “saints” – people who have lived that ism to the fullest. Look at their dying. Look at how their weakest, most vulnerable are treated. Look at the marriages of those who have lived their tenants. I could say that with a confidence that made me want to shout my gratitude to all who had gone before me.
