Student: Do the Christs in Brazilian churches sport as much blood as the Christs in Mexican churches?
Professor Zero: Yes.
Student: That is amazing.
Professor Zero: Why? Italian Christs have a great deal of blood as well. Bloodiness is a major characteristic of the Mediterranean and Mediterranean based Christ.
Student: How marvelous!
Professor Zero: It seems you consider bloody Christs best. What are the advantages of having especially bloody Christs?
Student: Well, they work much better! The point of having a Christ is so you can feel guilty. If you have a really bloody one, you feel guiltier!

I grew up in a very bloodless liberal Catholic church in the States. I’ve drifted away from the religion, but I don’t know whether that is data indicating that our Christs didn’t work effectively.
