As a follow up to "Nitpickyism," here are my picks for worst theological invention ever:
- Gnosticism, i.e., God only speaks to special people in private.
- Deism, i.e., God is not intimate with His creation (which rules out the Incarnation).
- Monotheism (Islam), i.e., God is one (as opposed to Trinitarian, i.e., God is three in one).
- Atheism, i.e., God is not. I don't know how much worse you can get.
