Although I rarely use the word c**k in my vocabulary, I do understand your usage here as a metaphor.
I am not at all shocked by it, as I understand the use of parody to comment about something or poke fun about a concept. I understand that you are not making fun of god per say, but about the concept of the god of the bible, which was created by men with c**ks.
The shock factor is often used in NLP. It can be a very effective tool to effect change.
Goofiness deserves a little parody. It is the belief system that is being examined. Not the christian and not even god, per say. Just the belief system.
