James 1:26

Censuring is a pleasing sin, extremely complaint with nature, and therefore evinces a man's being in a natural state. These sins of the tongue were the great sins of that age in which James wrote (as other parts of this epistle fully show); and it is a strong sing of a vain religion (says Dr. Manton) to be carried away with the evil of the times.

If any man among you seem to be religious,....

The character by which our author desires to be known: James, a servant of God, and of the Lord Jesus Christ. Though he was a prime-minister in Christ's kingdom, yet he styles himself only a servant. Note hence, Those who are highest in office or attainments in the church of Christ are but servants.

Seem to be religious - The words θρησκος and θρησκεια, which we translate religious and religion, (see the next verse), are of very uncertain etymology. Suidas, under the word θρησκευει, which he translates θεοσεβει, ὑπηρετει τοις θεοις, he worships or serves the gods, accounts for the derivation thus: “It is said that Orpheus, a Thracian, instituted the mysteries (or religious rites) of the Greeks, and called the worshipping of God θρησκευειν threskeuein, as being a Thracian invention.” Whatever its derivation may be, the word is used both to signify true religion, and superstition or heterodoxy.

If any man among you seem to be religious - Pious, or devout. That is, if he does not restrain his tongue, his other evidences of religion are worthless. A man may undoubtedly have many things in his character which seem to be evidences of the existence of religion in his heart, and yet there may be some one thing that shall show that all those evidences are false. Religion is designed to produce an effect on our whole conduct; and if there is any one thing in reference to which it does not bring us under its control, that one thing may show that all other appearances of piety are worthless. And bridleth not his tongue - Restrains or curbs it not, as a horse is restrained with a bridle. There may have been some reason why the apostle referred to this particular sin which is now unknown to us; or he may perhaps have intended to select this as a specimen to illustrate this idea, that if there is any one evil propensity which religion does not control, or if there is any one thing in respect to which its influence is not felt, whatever other evidences of piety there may be, this will demonstrate that all those appearances of religion are vain. For religion is designed to bring the whole man under control, and to subdue every faculty of the body and mind to its demands. If the tongue is not restrained, or if there is any unsubdued propensity to sin whatever, it proves that there is no true religion. But deceiveth his own heart - Implying that he does deceive his heart by supposing that any evidence can prove that he is under the influence of religion if his tongue is unrestrained. […]
