Respect of persons is inconsistent with the first principles of Christianity.
1. One great function of Christianity was to create a sphere in which there should be neither Jew nor Gentile, Greek nor barbarian, bond nor free. "All equal are within the Church's gate" is true, not only of the material building, but equally of the spiritual fabric of the Catholic Church, which, like her Divine Head, is no respecter of persons. Bengel well remarks that the equality of Christians, indicated by the name "brethren" (James 2:1), is the foundation of the admonition with which the chapter opens.
2. St. James gives but one instance of the kind of respect of persons which is forbidden, viz. the respect shown to the rich in assemblies of Christians for worship. Other forms of the same sin are common enough and are equally reprehensible, e.g. the homage paid to a man in society because he is rich, without regard to his character and moral worth. At the same time, it must not be forgotten that Christianity accepts as a fact class distinctions, and that we are bidden to give "honor to whom honor is due." "The Christian religion allows not that contempt for even earthly dignities affected by some of her followers, but springing more from envy and unruliness than aught besides. True reverence and submission are in no way condemned by this Scripture, but their excess and gross extreme, the preference for vulgar wealth, the adulation of success, the worship, in short, of some new golden calf" (Punchard).
3. Respect of persons, regard to outward appearances, the gold ring and the gay clothing, evince not merely evil thinking but want of faith (verse 4); i.e. a halting between God, who is no respecter of persons, and the world, which judges only by that which is external. How foolish also to regard the persons of men, when the object of our faith is the Lord of glory himself!
