Luke 16:18

Christ had told the Pharisees not to boast of their own righteousness, but to receive penitent sinners, and to redeem their sins by almsgiving. But they derided the Preacher of mercy, humility, and frugality; as it is said, And the Pharisees also, who were covetous, heard these things; and derided him: it may be for two reasons, either because He commanded what was not sufficiently profitable, or cast blame upon their past superfluous actions.

But the Lord detecting in them a hidden malice, proves that they make a presence of righteousness. Therefore it is added, And he said to them, you are they which justify yourselves before men.

They justify themselves before men who despise sinners as in a weak and hopeless condition, but fancy themselves to be perfect and not to need the remedy of almsgiving; but how justly the depth of deadly pride is to be condemned, He sees who will enlighten the hidden places of darkness. Hence it follows, But God knows your hearts.

And therefore you are an abomination to Him because of your arrogance, and love of seeking after the praise of men; as He adds, For that which is highly esteemed among men is abomination in the sight of God.

Now the Pharisees derided our Savior disputing against covetousness, as if He taught things contrary to the Law and the Prophets, in which many very rich men are said to have pleased God; but Moses also himself promised that the people whom he ruled, if they followed the Law, should abound in all earthly goods. These the Lord answers by showing that between the Law and the Gospel, as in these promises so also in the commands, there is not the slightest difference. Hence He adds, The Law and the Prophets were until John.

Not that the Law failed, but that the preaching of the Gospel began, for that which is inferior seems to be completed when a better succeeds.

He hereby disposes them readily to believe on Him, because if as far as John’s time all things were complete, I am He who am come. For the Prophets had not ceased unless I had come; but you will say, “how” were the Prophets until John, since there have been many more Prophets in the New than the Old Testament. But He spoke of those prophets who foretold Christ’s coming.

Now the ancient prophets knew the preaching of the kingdom of heaven, but none of them had expressly announced it to the Jewish people, because the Jews having a childish understanding were unequal to the preaching of what is infinite. But John first openly preached that the kingdom of heaven was at hand, as well as also the remission of sins by the laver of regeneration. Hence it follows, Since that time the kingdom of heaven is preached, and every one presses into it.

For the Law delivered many things according to nature, as being more indulgent to our natural desires, that it might call us to the pursuit of righteousness. Christ breaks through nature as cutting off even our natural pleasures. But therefore we keep under nature, that it should not sink us down to earthly things, but raise us to heavenly.

A great struggle befalls men in their ascent to heaven. For that men clothed with mortal flesh should be able to subdue pleasure and every unlawful appetite, desiring to imitate the life of angels, must be compassed with violence. But who that looking upon those who labor earnestly in the service of God, and almost put to death their flesh, will not in reality confess that they do violence to the kingdom of heaven.

They also do violence to the kingdom of heaven, in that they not only despise all temporal things, but also the tongues of those who desire their doing so. This the Evangelist added, when he said that Jesus was derided when He spoke of despising earthly riches.

But lest they should suppose that in His words, the Law and the Prophets were until John, He preached the destruction of the Law or the Prophets, He obviates such a notion, adding, And it is easier for heaven and earth to pass, than one tittle of the law should fail. For it is written, the fashion of this world passes away. But of the Law, not even the very extreme point of one letter, that is, not even the least things are destitute of spiritual sacraments. And yet the Law and the Prophets were until John, because that could always he prophesied as about to come, which by the preaching of John it was clear had come. But that which He spoke beforehand concerning the perpetual inviolability of the Law, He confirms by one testimony taken therefrom for the sake of example, saying, Whosoever puts away his wife, and marries another, commits adultery: and whosoever marries her that is put away from her husband, commits adultery; that from this one instance they should learn that He came not to destroy but to fulfill the commands of the Law.

For that to the imperfect the Law spoke imperfectly is plain from what he says to the hard hearts of the Jews, “If a man hate his wife, let him put her away,” because since they were murderers and rejoiced in blood, they had no pity even upon those who were united to them, so that they slew their sons and daughters for devils. But now there is need of a more perfect doctrine. Wherefore I say, that if a man puts away his wife, having no excuse of fornication, he commits adultery, and he who marries another commits adultery.

But we must first speak, I think, of the law of marriage, that we may afterwards discuss the forbidding of divorce. Some think that all marriage is sanctioned by God, because it is written, Whom God has joined, let not man put asunder. How then does the Apostle say, If the unbelieving depart, let him depart? Herein he shows that the marriage of all is not from God. For neither by God’s approval are Christians joined with Gentiles. Do not then put away your wife, lest you deny God to be the Author of your union. For if others, much more ought you to bear with and correct the behavior of your wife. And if she is sent away pregnant with children, it is a hard thing to shut out the parent and keep the pledge; so as to add to the parents’ disgrace the loss also of filial affection. Harder still if because of the mother you drive away the children also. Would you suffer in your lifetime your children to be under a step-father, or when the mother was alive to be under a step-mother? How dangerous to expose to error the tender age of a young wife. How wicked to desert in old age one, the flower of whose growth you have blighted. Suppose that being divorced she does not marry, this also ought to be displeasing to you, to whom though an adulterer, she keeps her troth. Suppose she marries, her necessity is your crime, and that which you suppose marriage, is adultery. But to understand it morally. Having just before set forth that the kingdom of God is preached, and said that one tittle could not fall from the Law, He added, Whosoever puts away his wife, &c. Christ is the husband; whomsoever then God has brought to His son, let not persecution sever, nor lust entice, nor philosophy spoil, nor heretics taint, nor Jew seduce. Adulterers are all such as desire to corrupt truth, faith, and wisdom.

But Christ prohibits divorce, saying, “Whosoever putteth away his wife, and marrieth another, committeth adultery; and whosoever marrieth her that is put away from her husband, also committeth adultery.” In order to forbid divorce, He makes it unlawful to marry a woman that has been put away. Moses, however, permitted repudiation in Deuteronomy: “When a man hath taken a wife, and hath lived with her, and it come to pass that she find no favour in his eyes, because he hath found unchastity in her; then let him write her a bill of divorcement and give it in her hand, and send her away out of his house.” You see, therefore, that there is a difference between the law and the gospel, between Moses and Christ? To be sure there is! But then you have rejected that other gospel which witnesses to the same verity and the same Christ. …

Because it is a law expressly appointed by Christ which he is about to read to them about the “not putting away a wife without fornication; “(S. Matt. v. 32., xix. 9; S. Mark x. 11; S. Luke xvi. 18 .) therefore he says, “Not I.” True it is what was before spoken though it were not expressly stated, yet it also is His decree. But this, you see, He had delivered in express words. So that the words “I and not I” have this difference of meaning. For that you might not imagine even his own words to be human, therefore he added, “For I think that I also have the Spirit of God.”
