James 3:2

For in many things we offend all - We all offend. The word here rendered offend, means to stumble, to fall; then to err, to fail in duty; and the meaning here is, that all were liable to commit error, and that this consideration should induce men to be cautious in seeking an office where an error would be likely to do so much injury. The particular thing, doubtless, which the apostle had in his eye, was the peculiar liability to commit error, or to do wrong with the tongue. Of course, this liability is very great in an office where the very business is public speaking. If anywhere the improper use of the tongue will do mischief, it is in the office of a religious teacher; and to show the danger of this, and the importance of caution in seeking that office, the apostle proceeds to show what mischief the tongue is capable of effecting.

If any man offend not in word - In his speech; in the use of his tongue.

The same is a perfect man - Perfect in the sense in which the apostle immediately explains himself; that he is able to keep every other member of his body in subjection. His object is not to represent the man as absolutely spotless in every sense, and as wholly free from sin, for he had himself just said that “all offend in many things;” but the design is to show that if a man can control his tongue, he has complete dominion over himself, as much as a man has over a horse by the bit, or as a steersman has over a ship if he has hold of the rudder. He is perfect in that sense, that he has complete control over himself, and will not be liable to error in anything. The design is to show the important position which the tongue occupies, as governing the whole man. On the meaning of the word perfect, see the notes at Job 1:1.

And able also to bridle the whole body - To control his whole body, that is, every other part of himself, as a man does a horse by the bridle. The word rendered “to bridle,” means to lead or guide with a bit; then to rein in, to check, to moderate, to restrain. A man always has complete government over himself if he has the entire control of his tongue. It is that by which he gives expression to his thoughts and passions; and if that is kept under proper restraint, all the rest of his members are as easily controlled as the horse is by having the control of the bit.
