John 1:17

"The law was given by Moses, but grace and truth came by Jesus Christ." See ye how gently, by a single word and by little and little, both John the Baptist and John the Disciple lead up their hearers to the highest knowledge, having first exercised them in humbler things? The former having compared to himself Him who is incomparably superior to all, thus afterwards shows His superiority, by saying, "is become before me," and then adding the words, "was before me": while the latter has done much more than he, though too little for the worthiness of the Only-Begotten, for he makes the comparison, not with John, but with one reverenced by the Jews more than John, with Moses. "For the law," saith he, "was given by Moses, but grace and truth came by Jesus Christ."

Observe his wisdom. He makes enquiry not concerning the person, but the things; for these being proved, it was probable that even the senseless would of necessity receive from them a much higher judgment and notion respecting Christ. For when facts bear witness, which cannot be suspected of doing so either from favor to any, or from malice, they afford a means of judging which cannot be doubted even by the senseless; for they remain to open view just as their actors may have arranged them, and therefore their evidence is the least liable to suspicion of any. And see how he makes the comparison easy even to the weaker sort; for he does not prove the superiority by argument, but points out the difference by the bare words, opposing "grace and truth" to "law," and "came" to "was given." Between each of these there is a great difference; for one, "was given," belongs to something ministered, when one has received from another, and given to whom he was commanded to give; but the other, "grace and truth came," befits a king forgiving all offenses, with authority, and himself furnishing the gift. Wherefore He said, "Thy sins be forgiven thee"; and again, "But that ye may know that the Son of Man hath power on earth to forgive sins (He saith to the sick of the palsy), Arise, take up thy bed, and go unto thine house."

"For the law was given by Moses"; which law held the guilty. For what saith the apostle? "The law entered that the offense might abound." It was a benefit to the proud that the offense abounded, for they gave much to themselves, and, as it were, attributed much to their own strength; and they were unable to fulfill righteousness without the aid of Him who had commanded it. God, desirous to subdue their pride, gave the law, as if saying: Behold, fulfill, and do not think that there is One wanting to command. One to command is not wanting, but one to fulfill.

This grace was not in the Old Testament, because the law threatened, did not bring aid; commanded, did not heal; made manifest, but did not take away our feebleness: but it prepared the way for that Physician who was to come with grace and truth; as a physician who, about to come to any one to cure him, might first send his servant that he might find the sick man bound. He was not sound; he did not wish to be made sound and lest he should be made sound, he boasted that he was so. The law was sent, it bound him; he finds himself accused, now, he exclaims against the bandage. The Lord comes, cures with somewhat bitter and sharp medicines: for He says to the sick, Bear; He says, Endure; He says, Love not the world, have patience, let the fire of continence cure thee, let thy wounds endure the sword of persecutions. Wert thou greatly terrified although bound? He, free and unbound, drank what He gave to thee; He first suffered that He might console thee, saying, as it were, that which thou fearest to suffer for thyself, I first suffer for thee. This is grace, and great grace. Who can praise it in a worthy manner?

"The law was given by Moses: grace and truth came by Jesus Christ." By a servant was the law given, and made men guilty: by an Emperor was pardon given, and delivered the guilty. "The law was given by Moses." Let not the servant attribute to himself more than was done through him. Chosen to a great ministry as one faithful in his house, but yet a servant, he is able to act according to the law, but cannot release from the guilt of the law. "The law," then, "was given by Moses: grace and truth came by Jesus Christ."
