James 1:26 - Coke's Commentary on the Holy Bible

And bridleth not his tongue— Not bridling his tongue, but deceiving his heart. Bishop Butler. As if the apostle had said, "It is impossible that any man should so much as seem to be religious, if he does not at least think that he bridles his tongue; but if he deceive himself in this important branch of religion, he is deceived in the whole of it." And indeed, to many sins of the tongue are committed without any apprehension of their being evil, that this caution, and this remark for the explication of it, are of great importance; considering how little many professors seem to be aware of the great evil of bitterly reproaching their brethren on account of their religious differences; a sin, which the apostle seems to have had particularly in his view.
