Second Instruction
2 Let us not therefore remain craving after the things of this life, neither after the luxury of the table, or costliness of raiment. For you have the most excellent of raiment, you have a spiritual table you have the glory from on high, and Christ has become to you all things, your table, your raiment, your home, your head, your stem. “For as many of you as were baptized into Christ, did put on Christ.” See how he has become raiment for you. Do you wish to learn how he becomes a table for you?
“He who eats me,” says He, “as I live because of the Father, he also shall live because of me;” and that he becomes a home for you, “he that eats my flesh abides in me, and I in him;” and that He is stem He says again, “I am the vine, you the branches,” and that he is brother, and friend, and bride-groom, “I no longer call you servants: for you are my friends;” and Paul again, “I espoused you to one husband, that I might present you as a pure virgin to Christ;” and again, “That he might be the first-born among many brethren;” and we become not his brethren only, but also his children, “For behold,” he says, “I and the children which God has given me” and not this only, but His members, and His body.
For as if what has been said were not enough to show forth the love and the good will which He has shown forth towards us, He has added another thing greater and nearer still, calling himself besides, our head. Knowing all these matters, beloved, requite your benefactor by the best conversation, and considering the greatness of the sacrifice, adorn the members of your body; consider what you receive in your hand, and never suffer it to strike any one, nor shame what has been honored with so great a gift by the sin of a blow.
Consider what you receive in your hand, and keep it clean from all covetousness and extortion; think that thou dost not receive this in your hand, but also puttest it to your mouth, and guard your tongue in purity from base and insolent words, blasphemy, perjury, and all other such things. For it is disastrous that what is ministered to by such most dread mysteries, and has been dyed red with such blood, and has become a golden sword, should be perverted to purposes of raillery, and insult, and buffoonery.
Reverence the honor with which God has honoured it, and bring it not down to the vileness of sin, but having reflected again that after the hand and the tongue, the heart receives this dread mystery, do not ever weave a plot against your neighbor, but keep your thoughts pure from all evil. Thus you shall be able to keep your eyes too, and your hearing safe. For is it not monstrous, after this mystic voice is borne from heaven— I mean the voice of the Cherubim— to defile your hearing with lewd songs, and dissolute melodies?
And does it not deserve the utmost punishment if, with the same eyes with which you look upon the unspeakable and dread mysteries, you look upon harlots, and dost commit adultery in your heart. You are called to a marriage, beloved: enter not in clad in sordid raiment, but take a robe suitable to the marriage. For if when men are called to a material marriage, though they be poorer than all others, they often possess themselves of or buy clean raiment, and so go to meet those who called them.
Do thou too who hast been called to a spiritual marriage, and to a royal banquet, consider what kind of raiment it would be right for you to buy, but rather there is not even need to purchase, yea he himself who calls you gives it you gratis, in order that you may not be able to plead poverty in excuse. Keep, therefore, the raiment which you received. For if you lose it, you will not be able to use it henceforth, or to buy it. For this kind of raiment is nowhere sold. Have you heard how those who were initiated, in old time, groaned, and beat their breasts, their conscience thereupon exciting them?
Beware then, beloved, that you do not at any time suffer like this. But how will you not suffer, if you dost not cast off the wicked habit of evil men? For this reason I said before, and speak now and will not cease speaking, if any has not rectified the defects in his morals, nor furnished himself with easily acquired virtue, let him not be baptized. For the laver is able to remit former sins, but there is no little fear, and no ordinary danger lest we return to them, and our remedy become a wound. For by how much greater the grace is, by so much is the punishment more for those who sin after these things.
