Sometimes things don't go as planned. My Parable of the Free Beer seems to have landed with a resounding thud, so perhaps a word of explanation is in order.
First, in case it wasn't obvious: yes, it was intended to be an allegory about theology, and Christian theology in particular. Replace "free beer" with "God's grace" and you have an almost verbatim transcript of sermons I have heard street evangelists deliver. In fact, I remember one street preacher in Santa Monica back when I was making my movie literally take a five dollar bill out of his wallet and ask, "Who would like five dollars?" and then go on to say that God's grace was infinitely more valuable and "all you have to do is take it." It wasn't literally free beer, but in those days you could still get a beer for five dollars. (Maybe you still can. I don't actually much care for beer.)
Second, it was supposed to be funny. If you didn't think it was, well, go get yourself a sense of humor. You can order one from Amazon nowadays.
Last but not least, the Parable was intended to make a serious point, namely, that without an independent standard (like evidence) how is an honest Seeker of the Truth supposed to choose from among the many religions on offer in today's market? You've got Christianity, which comes in so many flavors it is like the Baskin-Robbins of theology. Islam comes in two major varieties and handful of minor ones (like Sufism). Then you've got yer Buddhists and yer Hindus rounding out the world's major religions. But wait, as they say in the trade, there's more: there's Jews, Jains, Mormons, Scientologists, Raelians, Bahais, Satanists, Wiccans, and good old fashioned neo-pagans. (Give me that old time religion! It was good enough for grandpa so it's good enough for me.)
This is the question faith cannot answer: on what basis should one choose where to put one's faith?
