'Now answer me candidly, when you are going to the church to hear Mass, do you bear in mind that you are going to Calvary to be present at the Redeemer's death? If this thought was deep in your soul, would you venture into the holy place with unbecoming gait, or in apparel that is immodest? Had Magdalene come to the foot of the cross on Calvary, bedizened, perfumed, and with a display of finery such as she wore in the time of her sinfulness, what would have been said of her? Now what are we to say of you who go to the holy place dressed out as for some merry-making? What should be said of you if you were to profane that most august sacrifice by unbeseeming conduct, such as nods, salutations, laughter, whisperings, or worse than all, lascivious and sacrilegious glancings? Iniquity is abominable on all occasions and in all places, but the sins that are committed during Mass, and under the shadow of the altar, are sins which call down God's signal maledictions, "Cursed be he who doeth the work of the Lord deceitfully." (Jer. xlviii. 10.)'
St. Leonard of Port Maurice
