Ambrosiaster : Paul teaches that one should come to Communion with a reverent mind and with fear, so that the mind will understand that it must revere the one whose body it is coming to consume. — COMMENTARY ON PAUL'S EPISTLES John Chrysostom : In your conscience, where no one is present except God who sees all, there judge yourself, examine your sins. When you reflect upon your whole life, bring your sins to the court of the mind. Correct your mistakes, and in this way, with a clean conscience, touch the sacred table and participate in the holy sacrifice. — ON FASTING, HOMILY 6.5.22 John Chrysostom : "But let a man prove himself:" which also he saith in the second Epistle: "try your own selves, prove your own selves:" not as we do now, approaching because of the season rather than from any earnestness of mind. For we do not consider how we may approach prepared, with the ills that were within us purged out, and full of compunction, but how we may come at festivals and whenever all do so. But not thus did Paul bid us come: he knoweth only one season of access and communion, the purity of a man's conscience. Since if even that kind of banquet which the senses take cognizance of cannot be partaken of by us when feverish and full of bad humors, without risk of perishing: much more is it unlawful for us to touch this Table with profane lusts, which are more grievous than fevers. Now when I say profane lusts, I mean both those of the body, and of money, and of anger, and of malice, and, in a word, all that are profane. And it becomes him that approacheth, first to empty himself of all these things and so to touch that pure sacrifice. And neither if indolently disposed and reluctantly ought he to be compelled to approach by reason of the festival; nor, on the other hand, if penitent and prepared, should any one prevent him because it is not a festival. For a festival is a showing forth of good works, and a reverence of soul, and exactness of deportment. And if thou hast these things, thou mayest at all times keep festival and at all times approach. Wherefore he saith, "But let each man prove himself, and then let him approach." And he bids not one examine another, but each himself, making the tribunal not a public one and the conviction without a witness. — Homily on 1 Corinthians 28
