Galatians 5:9

V.9. A little leaven leaveneth the whole lump.

Paul’s concern for them meant nothing to some of the Galatians. Many had disowned him as their teacher and gone over to the false apostles. No doubt the false apostles took every occasion to defame Paul as a stubborn and contemptuous fellow who thought nothing of disrupting the unity of the churches for no other reason than his selfish pride and jealousy.

Others of the Galatians perhaps saw no harm in deviating a trifle from the doctrine of justification and faith. When they noticed that Paul made so much ado about a matter that seemed of no particular importance to them they raised their eyebrows and thought within themselves: “What if we did deviate a little from the doctrine of Paul? What if we are a little to blame? He ought to overlook the whole matter, and not make such an issue out of it, lest the unity of the churches be disturbed.” To this Paul replies: “A little leaven leaveneth the whole lump.”

Our opponents record the same complaints about us. They put us down as contentious, ill-tempered faultfinders. But these are the crafty passes of the devil, with which he seeks to overthrow our faith. We answer with Paul: “A little leaven leaveneth the whole lump.”

Small faults grow into big faults. To tolerate a trifling error inevitably leads to crass heresy. The doctrine of the Bible is not ours to take or to allow liberties with. We have no right to change even a tittle of it. When it comes to life we are ready to do, to suffer, to forgive anything our opponents demand as long as faith and doctrine remain pure and uncorrupt. The Apostle James says, “For whosoever shall keep the whole law and yet offend in one point, he is guilty of all.” Jam 2:10 This passage supports us over against our critics who claim that we disregard all charity to the great injury of the churches. We protest we desire nothing more than peace with all men. If they would only permit us to keep our doctrine of faith! The pure doctrine takes precedence before charity, apostles, or an angel from heaven.

Let others praise charity and concord to the skies; we magnify the authority of the Word and faith. Charity may be neglected at times without peril, but not the Word and faith. Charity suffers all things, it gives in. Faith suffers nothing; it never yields. Charity is often deceived but is never put out because it lies nothing to lose; it continues to do well even to the ungrateful. When it comes to faith and salvation in the midst of lies and errors that parade as truth and deceive many, charity has no voice or vote. Let us not be influenced by the popular cry for charity and unity. If we do not love God and His Word what difference does it make if we love anything at all?

Paul, therefore, admonishes both teachers and hearers not to esteem lightly the doctrine of faith as if it were a toy with which to amuse oneself in idle hours.
