You cannot “fast” from sin!

Thinking of a Lenten fast?  This author says some suggestions are just daft! You cannot fast from pornography! It’s always bad!!

We should always avoid sins, such as cruel words, unjust anger, selfishness, and, yes, pornography!  These are not good things that we temporarily abstain from, and then offer up as a sacrifice to God as part of our fast.  These simply are bad things that always displease Our Lord and which we should always avoid doing.

The notion of giving up sins as part of our Lenten resolution confuses the very nature or purpose of fasting, which is to deprive oneself of a good for the sake of a greater good – closeness to and ultimate union with God. You simply cannot “fast” from sin. If we have fasted from hurting words or pornography during Lent, do we then take these sins back up on Easter Monday proudly saying we will give them up again next Lent?  The very notion is absurd.
