Matthew 6:2

2.When thou doest alms He expressly reproves a long established custom, in which the desire of fame might not only be perceived by the eye, but felt by the hands. In places where streets or roads met, and in public situations, where large assemblies were wont to be held, they distributed alms to the poor. There was evident ostentation in that practice: for they sought crowded places, that they might be seen by multitudes, and, not satisfied with this, added even the sound of trumpets. (425) They pretended, no doubt, that it was to call the poor, as apologies are never wanting: but it was perfectly obvious, that they were hunting for applause and commendation. Now, when our service is rendered to the eyes of men, we do not submit our life to the judgment and approbation of God. Justly, therefore, does Christ say, that those persons, who exhibit themselves in this manner, have their reward: for they whose eyes are held by such vanity cannot look upon God.

For the same reason, all who are desirous of vain-glory are called hypocrites. Profane authors gave the name of ὑποκριταὶ , hypocrites, to those who personated assumed characters in plays and on the stage; and Scripture has applied this term to men who are double in heart and insincere. (426) There are various kinds of hypocrites. Some, though conscious of being very wicked, impudently give themselves out for good men before the world, and endeavor to conceal their vices, of which they have an inward conviction. Others allow themselves to proceed to such a pitch of audacity, that they venture to claim even perfect righteousness before God. Others do good, not from a desire to do what is right, nor on account of the glory of God, but only to obtain for themselves fame and a reputation for holiness. This last mentioned class Christ now describes, and he properly calls them hypocrites: for, having no proper object in view in the performance of good works, they assume a different character, that they may appear to be holy and sincere worshippers of God.
