Q: Is the custom of giving up something for Lent mandatory?

A: No, it is not mandatory. However, it is very profitable. By denying ourselves something we enjoy, we discipline our wills so that we are not slaves to our pleasures. Just as indulging the pleasure of eating leads to physical flabbiness and, if this is great enough, an inability to perform in physically demanding situations, indulging in pleasure in general leads to spiritual flabbiness and, if this is great enough, an inability to perform in spiritual demanding situations, we when the demands of morality require us to sacrifice something pleasurable (such as sex before marriage or not within the confines of marriage) or endure hardship (such as being scorned or persecuted for the faith). By disciplining the will to refuse pleasures when they are not sinful, a habit is developed which allows the will to refuse pleasures when they are sinful. There are few better ways to keep one’s priorities straight than by periodically denying ourselves things of lesser priority to show us that they are not necessary and focus our attention on what is necessary.

This denying of pleasure is not an end in itself. It is a only a means to an end. By training ourselves to resist temptations when they are not sinful, we train ourselves to reject temptations when they are sinful. We also express our sorrow over having failed to resist sinful temptations in the past.
