James 2:8-11

If ye fulfil the royal law The supreme law of the great King, which is love; and that to every man, poor as well as rich; ye do well The phrase, νομος βασιλικος, royal law, here admits of three interpretations. 1st, As the Greeks called a thing royal which was excellent in its kind, it may mean an excellent law. 2d, As the same Greeks, having few or no kings among them, called the laws of the kings of Persia, βασιλικοι νομοι, royal laws, the expression here may signify, the law made by Christ our King. 3d, This law, enjoining us to love our neighbour, may be called the royal law, because it inspires us with a greatness of mind, fit for kings, whose greatest glory consists in benevolence and clemency. The law or precept here spoken of was enjoined by Moses, but Christ carried it to such perfection, as it was to be practised among his followers, and laid such stress upon it, that he called it a new commandment, John 13:34; and his commandment, John 15:12. But if ye have respect to persons In this partial manner, ye commit, εργαζεσθε, ye work, sin That is, ye do a sinful action; and are convinced Or rather convicted, by the law, which I have just now mentioned: for that law enjoins you to love your neighbours as yourselves, and consequently to do them justice. For whosoever shall keep the whole law In every other instance; and yet offend in one point Knowingly; he is guilty of all He is liable to condemnation from the lawgiver, as if he had offended in every point. The Jewish doctors affirmed, that by observing any one precept of the law with care, men secured to themselves the favour of God, notwithstanding they neglected all the rest. Wherefore they recommended it to their disciples to make choice of a particular precept, in the keeping of which they were to exercise themselves. Whitby says, they commonly chose either the law of the sabbath, or the law of sacrifice, or the law of tithes, because they esteemed these the great commandments in the law. This corrupt Jewish doctrine St. James here expressly condemns; for he that said, Do not commit adultery, said also, Do not kill The apostle's meaning is, that all the commandments being equally enjoined by God, the man who despises the authority of God so far as to break any one of them habitually, would, in the like circumstances of temptation and opportunity, certainly break any other of them; consequently, in the eye of God, he is guilty of breaking the whole law: that is, he hath no real principle of piety or virtue in him.
