1 Corinthians 5:6

“Your glorying is not good, etc.] Their glorying in their outward flourishing condition, in their riches and wealth, and in their ministers, in their wisdom and parts when under such an humbling dispensation; and especially if their glorying was in the sin itself, and their connivance at it, it was far from being good, it was very criminal, as the consequence of it was dangerous: know ye not that a little leaven leaveneth the whole lump? This, in nature, is what everybody knows; and the proverb, which is much used by the Jews f54, was common in the mouths of all, and the meaning of it easy to be understood: thus, whether applied to the leaven of false doctrine, nothing is more manifest, than…”

“Your glorying in your own attainments and those of your favorite teachers (Co1 3:21; Co1 4:19; Co1 5:2), while all the while ye connive at such a scandal, is quite unseemly. a little leaven leaveth . . . whole lump-- (Gal 5:9), namely, with present complicity in the guilt, and the danger of future contagion (Co1 15:33; Ti2 2:17).”

“Your glorying - Your boasting; or confidence in your present condition, as if you were eminent in purity and piety. Is not good - Is not well, proper, right. Boasting is never good; but it is especially wrong when, as here, there is an existing evil that is likely to corrupt the whole church. When people are disposed to boast, they should at once make the inquiry whether there is not some sin indulged in, on account of which they should be humbled and subdued. If all individual Christians, and all Christian churches, and all people of every rank and condition, would look at things as they are, they would never find occasion for boasting. It is only when we are blind to the realities of the…”

“Your glorying - Either in your gifts or prosperity, at such a time as this, is not good. Know ye not that a little leaven - One sin, or one sinner. Leaveneth the whole lump - Diffuses guilt and infection through the whole congregation. 1 Corinthians 5:7”

“5:6-7 Yeast was often a symbol of sin (cp. Matt 16:6, 12; Mark 8:15; Luke 12:1; Gal 5:9). Jews ceremonially cleansed their homes of yeast before the annual Passover meal (Exod 12:19; 13:7). • Get rid of . . . this wicked person: Sin, if unaddressed, could spread throughout the church, just as yeast spreads throughout a batch of dough.”

“glorying: Co1 5:2, Co1 3:21, Co1 4:18, Co1 4:19; Jam 4:16 a little: Co1 15:33; Mat 13:33, Mat 16:6-12; Luk 13:21; Gal 5:9; Ti2 2:17 1 Corinthians 5:7”
