1 Corinthians 5:7

7. old leaven--The remnant of the "old" (Ep 4:22-24) heathenish and natural corruption. The image is taken from the extreme care of the Jews in searching every corner of their houses, and "purging out" every particle of leaven from the time of killing the lamb before the Passover (De 16:3, 4). So Christians are continually to search and purify their hearts (Psa 139:23, 24). as ye are unleavened--normally, and as far as your Christian calling is concerned: free from the leaven of sin and death (1Co 6:11). Paul often grounds exhortations on the assumption of Christian professors' normal state as realized (Ro 6:3, 4) [Alford]. Regarding the Corinthian Church as the Passover "unleavened lump" or mass, he entreats them to correspond in fact with this their normal state. "For Christ our Passover (Ex 12:5-11, 21-23; Joh 1:29) has been (English Version, "is") sacrificed for us"; that is, as the Jews began the days of unleavened bread with the slaying of the Passover lamb, so, Christ our Passover having been already slain, let there be no leaven of evil in you who are the "unleavened lump." Doubtless he alludes to the Passover which had been two or three weeks before kept by the Jewish Christians (1Co 16:8): the Gentile Christians probably also refraining from leavened bread at the love-feasts. Thus the Jewish Passover naturally gave place to our Christian Easter. The time however, of keeping feast (metaphorical; that is, leading the Christian life of joy in Christ's finished work, compare Pr 15:15) among us Christians, corresponding to the Jewish Passover, is not limited, as the latter, to one season, but is ALL our time; for the transcendent benefits of the once-for-all completed sacrifice of our Passover Lamb extends to all the time of our lives and of this Christian dispensation; in no part of our time is the leaven of evil to be admitted. For even--an additional reason, besides that in 1Co 5:6, and a more cogent one for purging out every leaven of evil; namely, that Christ has been already sacrificed, whereas the old leaven is yet unremoved, which ought to have been long ago purged out.

Verse 7. Purge out therefore, etc. Put away; free yourselves from.

The old leaven. The apostle here takes occasion, from the mention of leaven, to exhort the Corinthians to put away vice and sin. The figure is derived from the custom of the Jews in putting away leaven at the celebration of the passover. By the old leaven he means vice and sin; and also here the person who had committed the sin in their church. As the Jews, at the celebration of the passover, gave all diligence in removing leaven from their houses--searching every part of their dwellings with candles, that they might remove every particle of leavened bread from their habitations--so the apostle exhorts them to use all diligence to search out and remove all sin.

That ye may be a new lump. That you may be like a new mass of flour, or dough, before the leaven is put into it. That you may be pure and free from the corrupting principle.

As ye are unleavened. That is, as ye are bound by your Christian profession to be unleavened, or to be pure. Your very profession implies this, and you ought, therefore, to remove all impurity, and to become holy. Let there be no impurity, and no mixture inconsistent with that holiness which the gospel teaches and requires. The apostle here does not refer merely to the case of the incestuous person, but he takes occasion to exhort them to put away all sin. Not only to remove this occasion of offence, but to remove all impurity, that they might become entirely and only holy. The doctrine is, that Christians are by their profession holy, and that therefore they ought to give all diligence to remove everything that is impure.

For even Christ, etc. As the Jews, when their paschal lamb was slain, gave great diligence to put away all leaven from their dwellings, so we Christians, since our passover is slain, ought to give the like diligence to remove all that is impure and corrupting from our hearts. There can be no doubt here that the paschal lamb was a type of the Messiah; and as little that the leaven was understood to be emblematic of impurity and sin, and that their being required to put it away was intended to be an emblematic action designed to denote that all sin was to be removed and forsaken.

Our passover. Our paschal lamb, for so the word πασχα usually signifies. The sense is, "We Christians have a paschal lamb; and that lamb is the Messiah. And as the Jews, when their paschal lamb was slain, were required to put away all leaven from their dwellings, so we, when our paschal lamb is slain, should put away all sin from our hearts and from our churches." This passage proves that Paul meant to teach that Christ had taken the place of the paschal lamb--that that lamb was designed to adumbrate or typify him--and that consequently when he was offered, the paschal offering was designed to cease. Christ is often in the Scriptures compared to a lamb. See Isa 53:7, Jn 1:29; 1Pet 1:19, Rev 5:6,12.

Is sacrificed for us. Margin, Or slain--ετυθη. The word θυω may mean simply to slay or kill; but it is also used often in the sense of making a sacrifice as an expiation for sin, Acts 14:13,18, 1Cor 10:20. Comp. Gen 31:54, 46:1, Ex 3:18, 5:3,8,17; Ex 8:8,25-29, 13:15, 20:24, where it is used as the translation of the word , to sacrifice. It is used as the translation of this word no less than ninety-eight times in the Old Testament, and perhaps always in the sense of a sacrifice, or bloody offering. It is also used as the translation of the Hebrew word , and , to slay, to kill, etc., in Ex 12:21, 1Kgs 11:19, 2Chr 29:22, etc.; in all, in eleven places in the Old Testament. It is used in a similar sense in the New Testament, in Mt 22:4, Lk 15:23,27,30, Jn 10:10, Acts 10:13, 11:7. It occurs nowhere else in the New Testament than in the places which have been specified. The true sense of the word here is, therefore, to be found in the doctrine respecting the passover. That that was intended to be a sacrifice for sin is proved by the nature of the offering, and by the account which is everywhere given of it in the Old Testament. The paschal lamb was slain as a sacrifice. It was slain in the temple; its blood was poured out as an offering; it was sprinkled and offered by the priests in the same way as other sacrifices. See Ex 23:18, 34:25, 2Chr 30:15,16. And if so, then this passage means that Christ was offered as a sacrifice for sin--in accordance with the numerous passages of the New Testament, which speak of his death in this manner, Rom 3:25; and that his offering was designed to take the place of the paschal sacrifice, under the ancient economy.

For us. For us who are Christians. He died in our stead; and as the Jews, when celebrating their paschal feast, put away all leaven, so we, as Christians, should put away all evil from our hearts, since that sacrifice has now been made once for all.

Verse 7 Purge out therefore the old leaven - As it is the custom of the Jews previously to the passover to search their houses in the most diligent manner for the old leaven, and throw it out, sweeping every part clean; so act with this incestuous person. I have already shown with what care the Jews purged their houses from all leaven previously to the passover; see the note on Exo 12:8-19 (note), and on the term passover, and Christ as represented by this ancient Jewish sacrifice; see on Exo 12:27 (note), and my Discourse on the Nature and Design of the Eucharist.
