2 Timothy 2:14

Of these things put them in remembrance, charging them in the sight of the Lord, that they strive not about words, to no profit, to the subverting of them that hear.

In this, Paul moved to instruct Timothy with regard to the false teachers who had emerged in Ephesus.

Put them in remembrance of these things ... That is, remind the Christians under his care in Ephesus of the soul-inspiring truths just enunciated in the faithful saying.

Strive not about words, to no profit ... Needless and useless argumentation have been the bane of historical Christianity. At the time of the great Communist revolution in Russia, the Orthodox Church was engaged in a tremendous argumentative crisis over the making of church vestments! Many a time, Christians have plunged into useless and silly arguments while the citadel of their faith was destroyed. Not only are such arguments of no profit, as Paul said; but they are actively mischievous, destructive and subversive of true faith. Christians? They are commanded not to do it!
