Galatians 5:9

A little leaven [μ ι κ ρ α ζ υ μ η]. A proverbial warning, which appears also 1 Corinthians 5:6. It refers, not to the doctrine of the false teachers, but to the false teachers themselves. Comp. Mark 8:15. With the single exception of the parable, Matthew 13:33, leaven, in Scripture, is always a symbol of evil. Comp. Exodus 12:15; Exodus 12:19; Exodus 13:3; Exodus 13:7; Exodus 23:18; Leviticus 2:11; Deuteronomy 16:3. This, however, is no warrant for the nonsense which has been deduced from it, as that Jesus ' parable of the leaven contains a prophecy of the corruption of Christianity. Because leaven in Scripture is habitually the type of corruption, we are "none the less free to use it in a good sense as Christ did. One figure need not always stand for one and the same thing. The devil is 'a roaring lion, ' but Christ is also 'the lion of the tribe of Judah '" (Trench). It is an apt figure of secret, pervading energy, whether bad or good. A new interest is given to the figure by Pasteur's discovery that fermentation is a necessary consequence of the activity and growth of living organisms. 82 A very few of these Judaising intruders are sufficient to corrupt the whole church.

Lump [φ υ ρ α μ α]. P o. See on Romans 9:21.
