ecclesiotomy

The removal of religious doctrine from one's noggin.

A conversation between Dr. Jack the agnostic epistemology professor and his student:

Dr. Jack: Roni my dear, have you concluded your ecclesiotomy thesis paper?

Roni: Yes professor! My research has convinced me to move out of the rectory and spread the actual truth.

Dr. Jack: The actual truth?

Roni: Yeah! I can't wait 'till we get to the end of the textbook!

Dr. Jack: Oh dear.
