Tractates on the Gospel of John

¹ When our Lord Jesus Christ, as we have heard in the Gospel when it was read, had said that He was Himself the bread which came down from heaven, the Jews murmured and said, “Is not Jesus the son of Joseph, whose father and mother we know? How is it then that he says, I came down from heaven?” These Jews were far off from the bread of heaven, and knew not how to hunger after it. They had the jaws of their heart languid; with open ears they were deaf, they saw and stood blind.

This bread, indeed, requires the hunger of the inner man: and hence He says in another place, “Blessed are they that hunger and thirst after righteousness, for they shall be satisfied.” But the Apostle Paul says that Christ is for us righteousness. And, consequently, he that hungers after this bread, hungers after righteousness—that righteousness however which comes down from heaven, the righteousness that God gives, not that which man works for himself. For if man were not making a righteousness for himself, the same apostle would not have said of the Jews: “For, being ignorant of the righteousness of God, and wishing to establish their own righteousness, they are not subject to the righteousness of God.” Of such were these who understood not the bread that comes down from heaven; because being satisfied with their own righteousness, they hungered not after the righteousness of God.

What is this, God's righteousness and man's righteousness? God's righteousness here means, not that wherein God is righteous, but that which God bestows on man, that man may be righteous through God. But again, what was the righteousness of those Jews? A righteousness wrought of their own strength on which they presumed, and so declared themselves as if they were fulfillers of the law by their own virtue. But no man fulfills the law but he whom grace assists, that is, whom the bread that comes down from heaven assists.

“For the fulfilling of the law,” as the apostle says in brief, “is charity.” Charity, that is, love, not of money, but of God; love, not of earth nor of heaven, but of Him who made Heaven and earth. Whence can man have that love? Let us hear the same: “The love of God,” says he, “is shed abroad in our hearts by the Holy Spirit which is given unto us.” Wherefore, the Lord, about to give the Holy Spirit, said that Himself was the bread that came down from heaven, exhorting us to believe in Him. For to believe in Him is to eat the living bread. He that believes eats; he is sated invisibly, because invisibly is he born again. A babe within, a new man within. Where he is made new, there he is satisfied with food.
