Here is an image that is practically guaranteed to be offensive to all Christians. If you're a Christian that likes the futurist material on this blog and doesn't care for mockery/criticism of your religion, skip it. Here is the atheist version.
It says the following, but using common terms instead of Christian terms:
"The belief that Jesus can make you live forever if you participate in Holy Communion and accept him as your Lord and Savior, so he can grant you freedom from Original Sin because Eve was convinced by Satan to eat from the Tree of Knowledge of Good and Evil."
The linked material is a pithy image posted to prompt questioning of the foundations of a popular world religion. If you're offended, ask yourself, "why am I receptive to criticism of everything but my religion?"
This image isn't new, and I believe it originated on 4chan, but what's interesting is that now it appears in the top Google image search results for "Christianity".
