Grace in the sacrament…

In the life of the body a man is sometimes sick, and unless he takes medicine, he will die. Even so in the spiritual life a man is sick on account of sin. For that reason he needs medicine so that he may be restored to health; and this grace is bestowed in the Sacrament of Penance.
–Saint Thomas Aquinas (1225-1274)

The devil catches…

The usual snare with which the devil catches the young is to fill them with shame when they are about to confess their sins. When he pushes them to commit sins, he removes all shame, as if there were nothing wrong with it, but when they are going to confession, he returns that shame magnified and tries to convince them that the priest will be shocked by their sins and will no longer think well of them. Thus the devil tries to drive souls to the brink of eternal damnation. Oh, how many lads does Satan steal from God – sometimes forever – by this trick.
–Saint John Bosco (1815-1888)

If you sin, confess it…

First of all, do everything you can to avoid offending God, but if unfortunately you should commit sin, do not let the devil prevail upon you to not confess it. Remember that the confessor is a father who is eager to do all he can for you and [to] protect you from all possible harm.
–Saint John Bosco (1815-1888)
