This is why I love traditional Catholicism! This is an excerpt from the Baltimore Catechism that I found:
"Q. 1311. What are rash judgment, backbiting, slander and detraction?
A. Rash judgment is believing a person guilty of sin without a sufficient cause.
Backbiting is saying evil things of another in his absence.
Slander is telling lies about another with the intention of injuring him. Detraction is revealing the sins of another without necessity."
Can you imagine if this stuff was still taught?? This is what almost every Catholic I have ever met on Long Island needs to learn.
