Whoever is chaste before marriage is the same after marriage. Those who learned adultery before marriage, do the same afterwards. It is written in the Divine Scriptures “All bread is sweet to the adulterer” (Sirach 23:17). For this reason, a crown is placed on the head (in the altar), as a sign of victory. They are entering the wedding not conquered or oppressed by lust. There is no reason to put a crown on the head of whoever gets into the love of pleasures and surrenders his soul to adultery, because he has been defeated.Instill this in them, teach and pressure them by all means.

—St. John Chrysostom
