I’d like to carry on a discussion on the Sacrament of Penance. I’ve been reading on the subject and have more questions now than before I started.
Let’s start with mortal sin. I know in order for a sin to be considered mortal one of the conditions is that it must be a grave matter. The CCC states that a “grave matter is specified by the Ten Commandments, corresponding to the answer of Jesus to the rich young man: 'Do not kill, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honor your father and your mother.”
This is confusing to me. Are all sins against the 10 Commandments considered grave? Don’t the 10 Commandments encompass all sin both venial & mortal? The term “grave” seems so subjective. I have found no source that makes the matter of gravity clear to me.
