Luke 5:32

And another Scripture says, "I came not to call the righteous, but sinners." This means that those who are perishing must be saved. For it is indeed a great and admirable thing to establish not the things which are standing, but those that are falling. Thus also did Christ desire to save the things which were perishing, [Matthew 18:11] and has saved many by coming and calling us when hastening to destruction.

But how does God love righteousness, and David has never seen the righteous man forsaken, if the righteous are excluded, the sinner called; unless you understand that He meant by the righteous those who boast of the law, (Ps. 11:7, Ps. 37:25.) and seek not the grace of the Gospel. Now no one is justified by the law, but redeemed by grace. He therefore calls not those who call themselves righteous, for the claimers to righteousness are not called to grace. For if grace is from repentance, surely he who despises repentance renounces grace.

But He calls those sinners, who considering their guilt, and feeling that they cannot be justified by the law, submit themselves by repentance to the grace of Christ.

It follows, I came not to call the righteous, but sinners to repentance. As if He should say, So far am I from hating sinners, that for their sakes only I came, not that they should remain sinners, but be converted and become righteous.

Now He speaks of the righteous ironically, as when He says, Behold Adam is become as one of us. (Gen. 3:22.) But that there was none righteous upon the earth St. Paul shows, saying, All have sinned, and need the grace of God. (Rom. 3:23.)

(ubi sup.) Hence He adds, to repentance, which serves well to explain the passage, that no one should suppose that sinners, because they are sinners, are loved by Christ, since that similitude of the sick plainly suggests what our Lord meant by calling sinners, as a Physician, the sick, in order that from iniquity as from sickness they should be saved.

“I have not come to call the just but sinners” can also be properly understood in this way. He has not called those who, wishing to establish their own justice, have not been made subject to the justice of God. He calls those who, being conscious of their weakness, are not ashamed to confess that we have all offended in many things. In them too is fulfilled his saying that he had not come to call the just but sinners. That is, he does not call the exalted but the humble. He does not call those puffed up about their own justice but those showing themselves devotedly subject to the one who justifies the wicked. Such people, when they are converted, bear witness with a sincere heart that they must not be regarded as just, but sinners.It is a pleasure to remember, beloved, … to what a height of justice the Lord fetched Matthew, whom he chose out of his tax collecting activities in order to increase for sinners their hope of forgiveness. The apostolic band into which he was incorporated teaches what kind of person he became.

The greatest barrier I have met is the almost total absence from the minds of my audience of any sense of sin. This has struck me more forcibly when I spoke to the R.A.F. than when I spoke to students: whether (as I believe) the proletariat is more self-righteous than other classes, or whether educated people are cleverer at concealing their pride, this creates for us a new situation. The early Christian preachers could assume in their hearers, whether Jews, Metuentes, or Pagans, a sense of guilt. (That this was common among Pagans is shown by the fact that both Epicureanism and the mystery religions both claimed, though in different ways, to assuage it.) Thus the Christian message was in those days unmistakably the Evangelium, the Good News. It promised healing to those who knew they were sick. We have to convince our hearers of the unwelcome diagnosis before we can expect them to welcome the news of the remedy.
