God and the Devil cannot exist in the same body.

An American priest working in Mexico is considered a saint by many local parishioners. However, due to a botched exorcism, he carries a secret that’s eating him alive until he gets an opportunity to face his demon one final time.
In The Exorcism of God, consciousness is carried by monsters and creatures — a plane of “possession horror”. The story fights on E8/E9/E10 of the E0–E14 reality ladder, compressing religion, faith, sin, authority, mortality.
