We gave a daily instruction on right conduct when the readings were taken from the history of the patriarchs or the maxims of Proverbs. These readings were intended to instruct and train you, so that you might grow accustomed to the ways of our forefathers, entering into their paths and walking in their footsteps, in obedience to God’s commands. Now the season reminds us that we must speak of the mysteries, setting forth the meaning of the sacraments. If we had thought fit to teach these things to those not yet initiated through baptism, we should be considered traitors rather than teachers. Then, too, the light of the mysteries is of itself more effective where people do not know what to expect than where some instruction has been given beforehand. Open then your ears. Enjoy the fragrance of eternal life, breathed on you by means of the sacraments. We explained this to you as we celebrated the mystery of “the opening” when we said: Effetha, that is, be opened. Everyone who was to come for the grace of baptism had to understand what he was to be asked, and must remember what he was to answer. This mystery was celebrated by Christ when he healed the man who was deaf and dumb, in the Gospel which we proclaimed to you.
