Seven Deadly Sins For Dummies

Ok, you know what? There are seven cardinal sins in traditional Catholic theology. SEVEN. Originally, yes, there were eight principle vices but this list was reduced to seven and restructured around the 6th century, and the names of the Sins in FMA are clearly derived from the much more well-known later tradition set forth by Gregory of seven.

And, for the real idiots in the audience, the seven cardinal sins are: lust, gluttony, sloth, avarice, anger, envy and pride.

Now, what's so special about these seven?
Well, you have to know a little bit about classical Catholic theology, and in particular, what sin is.
