Let us keep the feast - Margin, "Holy day" ἑορτάζωμεν heortazōmen. This is language drawn from the paschal feast, and is used by Paul frequently to carry out and apply his illustration. It does not mean literally the paschal supper here - for that had ceased to be observed by Christians - nor the Lord's Supper particularly; but the sense is "As the Jews when they celebrated the paschal supper, on the slaying and sacrifice of the paschal lamb, put away all leaven - as emblematic of sin - so let us, in the slaying of our sacrifice, and in all the duties, institutions and events consequent thereon, put away all wickedness from our hearts as individuals, and from our societies and churches. Let us engage in the service of God putting away by all evil."

Not with the old leaven - Not under the influence, or in the indulgence of the feelings of corrupt and unrenewed human nature - The word "leaven" is very expressive of that former or "old" condition, and denotes the corrupt and corrupting passions of our nature before it is renewed.

The leaven of malice - Of unkindness and evil - which would diffuse itself, and pervade the mass of Christians. The word "malice" (κακίας kakias) denotes "evil" in general.

And wickedness - Sin; evil. There is a particular reference here to the case of the incestuous person. Paul means that all wickedness should be put away from those who had been saved by the sacrifice of their "Passover," Christ; and, therefore, this sin in a special manner.

But with the unleavened bread ... - That is, with sincerity and truth. Let us be sincere, and true, and faithful; as the Jews partook of bread unleavened, which was emblematic of purity, so let us be sincere and true. It is implied here that this could not be done unless they would put away the incestuous person - No Christians can have, or give evidence of sincerity, who are not willing to put away all sin.

Therefore let us keep the feast - It is very likely that the time of the passover was now approaching, when the Church of Christ would be called to extraordinary acts of devotion, in commemorating the passion, death, and resurrection of Christ; and of this circumstance the apostle takes advantage in his exhortation to the Corinthians. See the Introduction, Section 12.

Not with old leaven - Under the Christian dispensation we must be saved equally from Judaism, heathenism, and from sin of every kind; malice and wickedness must be destroyed; and sincerity and truth, inward purity and outward holiness, take their place.

The apostle refers here not more to wicked principles than to wicked men; let us keep the feast, not with the old leaven - the impure principles which actuated you while in your heathen state; neither with the leaven of malice and wickedness, κακιας και πονηριας, wickedness, radical depravity, producing unrighteousness in the life; nor with the persons who are thus influenced, and thus act; but with the unleavened bread, αλλ' εν αζυμοις, but with upright and godly men, who have sincerity, ειλικρινεια, such purity of affections and conduct, that even the light of God shining upon them discovers no flaw, and truth - who have received the testimony of God, and who are inwardly as well as outwardly what they profess to be.

The word πονηριας, which we translate wickedness, is so very like to πορνειας, fornication, that some very ancient MSS. have the latter reading instead of the former; which, indeed, seems most natural in this place; as κακιας, which we translate malice, includes every thing that is implied in πονηριας, wickedness whereas πορνειας, as being the subject in question, see 1 Corinthians 5:1, would come more pointedly in here: Not with wickedness and fornication, or rather, not with wicked men and fornicators: but I do not contend for this reading.

Therefore let us keep the feast,.... Not the feast of the passover, which was now ceased, though this is said in allusion to it; when the master of the house used to say (l),

"everyone that is hungry, let him come and eat; he that hath need, let him come "and paschatize", or keep the feast of the passover:''

but rather the feast of the Lord's supper is here meant, that feast of fat things Isaiah prophesied of; in which are the richest entertainments, even the flesh and blood of Christ; though it seems best to understand it of the whole course of a Christian's life, spent in the exercise of spiritual joy and faith in Christ; he that is of a merry heart, as the believer of all men in the world has reason to be of, "hath a continual feast", Proverbs 15:15 of spiritual mirth and pleasure, rejoicing always in Christ, as he ought to do: which feast, or course of life, is to be kept "not with old leaven"; in the old, vain, sinful manner of conversation, as before:

neither with the leaven of malice and wickedness; not in malice to any man, or one another, nor in any sort of wickedness, living in no known sin, and allowing of it:

but with the unleavened bread of sincerity; as opposed to malice, of sincere love to God and Christ, and to his people: and of truth; of Gospel doctrine, discipline, and conversation.

Let us keep the feast (ἑορτάζωμεν)

Only here in the New Testament. The epistle was probably written a short time before the Passover. See 1 Corinthians 16:8.

Sincerity (εἰλικρινείας)

See on pure minds, 2 Peter 3:1.

Truth

Bengel observes: "Sincerity takes care not to admit evil with the good; truth, not to admit evil instead of good."

Therefore let us keep the {g} feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.

(g) Let us lead our whole life as it were a continual feast, honestly and uprightly.

5:8 Let us keep the feast. Let us keep feast, or festival. There is no article in the Greek. The reference is not to the Lord's Supper, or to Easter, as some have supposed, so much as to a constant duty. We always have a Paschal Lamb; hence it is always our duty to keep festival by casting out all leaven; either the

old leaven of heathen vice, or of

the leaven of malice and wickedness, or any sin.

5:8 Therefore let us keep the feast - Let us feed on him by faith. Here is a plain allusion to the Lord's supper, which was instituted in the room of the passover. Not with the old leaven - Of heathenism or Judaism. Malignity is stubbornness in evil. Sincerity and truth seem to be put here for the whole of true, inward religion.

the feast: or, holyday

8. not . old leaven-of our unconverted state as Jews or heathen.

malice-the opposite of "sincerity," which allows no leaven of evil to be mixed up with good (Mt 16:6).

wickedness-the opposite of "truth," which allows not evil to be mistaken for good. The Greek for "malice" means the evil habit of mind; "wickedness," the outcoming of the same in word and deed. The Greek for "sincerity" expresses literally, a thing which, when examined by the sun's light, is found pure and unadulterated.

5:1-8 The apostle notices a flagrant abuse, winked at by the Corinthians. Party spirit, and a false notion of Christian liberty, seem to have saved the offender from censure. Grievous indeed is it that crimes should sometimes be committed by professors of the gospel, of which even heathens would be ashamed. Spiritual pride and false doctrines tend to bring in, and to spread such scandals. How dreadful the effects of sin! The devil reigns where Christ does not. And a man is in his kingdom, and under his power, when not in Christ. The bad example of a man of influence is very mischievous; it spreads far and wide. Corrupt principles and examples, if not corrected, would hurt the whole church. Believers must have new hearts, and lead new lives. Their common conversation and religious deeds must be holy. So far is the sacrifice of Christ our Passover for us, from rendering personal and public holiness unnecessary, that it furnishes powerful reasons and motives for it. Without holiness we can neither live by faith in him, nor join in his ordinances with comfort and profit.
