Hi teachccd,
Actually, you
can commit a mortal sin, even if
objectively the matter is not grave (or even sinful). The analysis involves a distinction between
material sin and
formal sin.
Material sin refers to the objective sinfulness of the act, whereas formal sin refers to the subjective awareness of the actor.
A material sin is present when an action in fact violates moral law, regardless of whether or not the actor is aware that it does. A formal sin is present if the actor is aware that an action violates moral law,
regardless of whether or not it actually does.
One may be mistaken about the sinfulness of an action in one of two ways and still commit formal sin:1. Performing an objectively good or indifferent action while
believing it to violate moral law when in fact it does not (a mistake of law); or
- Performing an action which one believes is objectively sinful, but cannot objectively be so (a mistake of fact).
An example of the first case would be your example of hugging someone while believing it to be a morally prohibited act.
An example of the second case would be the person who intentionally misses mass on Saturday thinking it was Sunday.
Most of the time when we sin it is both a material and formal sin. However the moral culpability stems from the formal sin, and that is what we confess.
What do you think?
