{5} For whosoever shall keep the whole law, and yet offend in one point, he is guilty of {g} all.

(5) A new argument to prove the same conclusion: Those who neglect some and ambitiously honour others do not love their neighbours. For they do not obey God if they remove from the commandments of God those things that are not convenient for them. Rather they are guilty of breaking the whole law, even though they observe part of it.

(g) Not that all sins are equal, but because he who breaks one small part of the law, offends the majority of the given law.

People's New Testament

2:10 Whoever shall keep the whole law. If the law is broken by respect of persons, the whole law is broken.

Yet offend in one point, he is guilty of all. He who willfully breaks one command is a law breaker and is guilty before the law.

Wesley's Notes

2:10 Whosoever keepeth the whole law, except in one point, he is guilty of all - Is as liable to condemnation as if he had offended in every point.

Jamieson-Fausset-Brown Bible Commentary

10. The best manuscripts read, "Whosoever shall have kept the whole law, and yet shall have offended (literally, 'stumbled'; not so strong as 'fall,' Ro 11:11) in one (point; here, the respecting of persons), is (hereby) become guilty of all." The law is one seamless garment which is rent if you but rend a part; or a musical harmony which is spoiled if there be one discordant note [Tirinus]; or a golden chain whose completeness is broken if you break one link [Gataker]. You thus break the whole law, though not the whole of the law, because you offend against love, which is the fulfilling of the law. If any part of a man be leprous, the whole man is judged to be a leper. God requires perfect, not partial, obedience. We are not to choose out parts of the law to keep, which suit our whim, while we neglect others.

Matthew Henry's Concise Commentary

2:1-13 Those who profess faith in Christ as the Lord of glory, must not respect persons on account of mere outward circumstances and appearances, in a manner not agreeing with their profession of being disciples of the lowly Jesus. St. James does not here encourage rudeness or disorder: civil respect must be paid; but never such as to influence the proceedings of Christians in disposing of the offices of the church of Christ, or in passing the censures of the church, or in any matter of religion. Questioning ourselves is of great use in every part of the holy life. Let us be more frequent in this, and in every thing take occasion to discourse with our souls. As places of worship cannot be built or maintained without expense, it may be proper that those who contribute thereto should be accommodated accordingly; but were all persons more spiritually-minded, the poor would be treated with more attention that usually is the case in worshipping congregations. A lowly state is most favourable for inward peace and for growth in holiness. God would give to all believers riches and honours of this world, if these would do them good, seeing that he has chosen them to be rich in faith, and made them heirs of his kingdom, which he promised to bestow on all who love him. Consider how often riches lead to vice and mischief, and what great reproaches are thrown upon God and religion, by men of wealth, power, and worldly greatness; and it will make this sin appear very sinful and foolish. The Scripture gives as a law, to love our neighbour as ourselves. This law is a royal law, it comes from the King of kings; and if Christians act unjustly, they are convicted by the law as transgressors. To think that our good deeds will atone for our bad deeds, plainly puts us upon looking for another atonement. According to the covenant of works, one breach of any one command brings a man under condemnation, from which no obedience, past, present, or future, can deliver him. This shows us the happiness of those that are in Christ. We may serve him without slavish fear. God's restraints are not a bondage, but our own corruptions are so. The doom passed upon impenitent sinners at last, will be judgment without mercy. But God deems it his glory and joy, to pardon and bless those who might justly be condemned at his tribunal; and his grace teaches those who partake of his mercy, to copy it in their conduct.
