Snarkily rebutting a claim that AA is “secular”

An acquaintance of mine, at a conference, ran into an apparently long-term AA member who defended, probably vociferously, the idea that Alcoholics Anonymous is a secular organization.

Just how did he defend the idea that AA is secular? Your “higher power” can be a doorknob? I know people everywhere at the end of AA meetings don’t actually pray the religious Lord's Prayer, but instead:

Our doorknob who art on the door
Hallowed be thy brass;
Thy key tumbler work;
Thy doors open quickly, at home as at work.
Give us this day our daily security;
Forgive us our fumbled keys
As we forgive others who drop theirs, too.
Lead us not into stripped-out locks,
But deliver a locksmith quickly.
For thine is the safety, and the reliability, and the universality.
Namaste.
