The New John Gill Exposition of the Entire Bible1 Corinthians 5:6
Your glorying is not good…
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?
nature, is what everybody knows; and the proverb, which is much
used by the Jews F6, 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 when this
is let alone, and a stop is not put to it, it increases to more
ungodliness; or to vice and immorality, as here; which if not taken
notice of by a church, is not faithfully reproved and severely
censured, as the case requires, will endanger the whole community;
it may spread by example, and, under the connivance of the church,
to the corrupting of good manners, and infecting of many.
F6 Neve Shalom apud Caphtor, fol. 41. 1.
