Before passing a particular bit of theology on to us nontheists for purposes of persuasion, theists would do well to run it through a rudimentary test suite, just to see how the argument holds up in more...neutral contexts.
So, wherever the prospective argument contains the term 'God' or its equivalent, simply substitute one or more of the following:
The Celestial Teapot
Now let's apply this to a sample text. Take this one, due to Joseph Ratzinger (made topical by Ross Douthat):
Thus, to the extent Ratzinger's argument entails the "unrejectability" of belief in God, it entails the unrejectability of belief in (inter alia) the Celestial Teapot. Convinced?
Of course, this doesn't prove anything about gods, cryptofauna or satellite cookware. But it will (if you are a theist) give you critical insight into how ridiculous your argument sounds to us.
