Crypto-Atheists

The idea scares the hell out of me: namely, that
one of the people in my congregation is an Atheist
masquerading as a Christian for social advantage
(or sexual advantage, for that matter).

Is there some tried and tested method that allows me
to determine whether or not a person is a true believer?

You are engaging in a logical fallacy known as an "inductive fallacy." Colloquially speaking, you are overgeneralizing.

Furthermore, your statement is not internally or externally consistent, as you have combined the asserted properties of the individuals in your list in the final statement of properties. However, you do not claim, nor is there support for the assertions that

1. Hitler was communist
2. Lenin was a nazi
3. Karl Marx was a nazi
4. Stalin was a nazi

In conclusion, you are a huge faggot who has wasted your time and mine without regard for the snack I anticipated eating seven minutes ago.
