"What then? Do we forbid marriage? By no means. But those who do not wish to marry we direct toward preserving virginity, teaching that it is most honorable. In the same way, from the fact that gold is most honorable, it does not follow that silver is dishonorable. Therefore let the one who can take hold of the gold of virginity. Let the one who cannot do this receive the silver of marriage."
"They call both marriage and most foods abominable, in insult to their Creator, who created these things for use," says blessed Theodoret. "The Apostle does not reject celibacy and abstinence, but accuses those who compel others to reckon them as law."
According to St. John Chrysostom's explanation, "By the expression 'every creation of God is good,' the Apostle here designates what can be used as food. If all such things are God's creation, then they are good, for 'all things are very good' (Gen 1:31). If all are good, what does it mean that 'it is sanctified by the word and prayer'? For it is obvious that what is sanctified is regarded as unclean. These words should not be understood in that way. Here the Apostle speaks against those who considered certain foods defiled. Therefore he sets forth two chief thoughts. First, there is no creation that is defiled. Second, if something were defiled, we have a remedy against it: sign it with the sign of the Cross, give thanks, glorify God, and every impurity disappears." "The unclean thing is the will that does not thank God."
"In these words of the Apostle," says Bishop Theophan, "one sees the beginning of prayers before and after eating food, as well as of sacred readings during the meal. As for the forbidding of marriage, is this not a product of the harsh treatment of the flesh that appeared in Colossae (2:23)? It was very natural to add the forbidding of marriage to it, and the Ephesians did so."
Our new interpreter, P. Polyansky, refuting Baur's view of the heretics of the Epistle as Gnostics, finds that Gnostics are plainly not meant here. Rather, a special kind of Ephesian ascetics is in view. They came forward with their teaching on celibacy in opposition to Ephesian dissoluteness, but they did so so sharply and unskillfully that the Apostle, who in other cases praised asceticism in the Epistles to the Romans and Corinthians, had to speak disapprovingly here of its extremes.
In conclusion of his judgments about the clean and the unclean, he says: "The Apostle's speech does not at all have Gnostic truths in view. The Apostle attributes the teaching about clean and unclean to those who turned away from the truth. Through this they reached intellectual and moral dissoluteness and, having lost a pure conscience, began dividing the one creation of God into two categories, clean and unclean. Meanwhile, for those morally pure, there is nothing unclean in the use of food. The notion that something is unclean depends entirely on the impurity of the mind and conscience of the one who forms it."
