James 1:26
If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion is vain.
If any man among you seem to be religious,.... By his preaching, or praying, and hearing, and other external duties of religion, he is constant in the observance of; and who, upon the account of these things, "thinks himself to be a religious man", as the Vulgate Latin, Syriac, and Arabic versions render it; or is thought to be so by others:
and bridleth not his tongue; but boasts of his works, and speaks ill of his brethren; backbites them, and hurts their names and characters, by private insinuations, and public charges without any foundation; who takes no care of what he says, but gives his tongue a liberty of speaking anything, to the injury of others, and the dishonour of God, and his ways: there seems to be an allusion to
but deceiveth his own heart; with his show of religion, and external performances; on which he builds his hopes of salvation; of which he is confident; and so gives himself to a loose way of talking what he pleases:
this man's religion is vain; useless, and unprofitable to himself and others; all his preaching, praying, hearing, and attendance on the ordinances will be of no avail to him; and he, notwithstanding these, by his evil tongue, brings a scandal and reproach upon the ways of God, and doctrines of Christ.
