Tractates on the Gospel of John

² In the first place, then, your Charity ought to know that it is Christ Himself as crucified, wherewith the apostle says that he has fed those who are babes as with milk; but His flesh itself, in which was witnessed His real death, that is, both His real wounds when transfixed and His blood when pierced, does not present itself to the minds of the carnal in the same manner as to that of the spiritual, and so to the former it is milk, and to the latter it is meat; for if they do not hear more than others, they understand better.

For the mind has not equal powers of perception even for that which is equally received by both in faith. And so it happens that the preaching of Christ crucified, by the apostle, was at once to the Jews a stumbling-block, and to the Gentiles foolishness; and to those who are called, both Jews and Greeks, the power of God, and the wisdom of God; but to the carnal, as babes who held it only as a matter of faith, and to the spiritual, as those of greater capacity, who perceived it as a matter of understanding; to the former, therefore, as a milk-draught, to the latter as solid food: not that the former knew it in one way out in the world at large, and the latter in another way in their secret chambers; but that what both heard in the same measure when it was publicly spoken, each apprehended in his own measure.

For inasmuch as Christ was crucified for the very purpose of shedding His blood for the remission of sins, and of divine grace being thereby commended in the passion of His Only-begotten, that no one should glory in man, what understanding had they of Christ crucified who were still saying, “I am of Paul”? Was it such as Paul himself had, who could say, “But God forbid that I should glory, save in the cross of our Lord Jesus Christ”? In regard, therefore, even to Christ crucified, he himself found food in proportion to his own capacity, and nourished them with milk in accordance with their infirmity.

And still further, knowing that what he wrote to the Corinthians might doubtless be understood in one way by those who were still babes, and differently by those of greater capacity, he said, “If any one among you is a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandment of the Lord; but if any man be ignorant, let him be ignorant.” Assuredly he would have the knowledge of the spiritual to be substantial, wherever not only faith had found a suitable abode, but a certain power of understanding was possessed; and whereby such believed those very things which as spiritual they likewise acknowledged.

But “let him be ignorant,” he says, who “is ignorant;” because it was not yet revealed to him to know that which he believes. When this takes place in a man's mind, he is said to be known of God; for it is God who endows him with this power of understanding, as it is elsewhere said, “But now, knowing God, or rather, being known of God.” For it was not then that God first knew those who were foreknown and chosen before the foundation of the world; but then it was that He made them to know Himself.
