Matthew Poole and continuators on James 2:10

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

This is not an Assertion, that any Man doth keep the whole Law so as to offend but in one point, but a supposition that if, or admitting such a one were.

All the rest of the Law, that one point only of the whole being excepted.

Slip, or trip, or stumble at; it seems to signify the least failing in any point of the Law.

Guilty of the breach, and obnoxious to the punishment of all; not distributively, or separately, as if he transgressed every Precept distinctly; but 1. conjunctively or copulatively, he is guilty of not keeping the whole Law, though not of breaking each particular Command; he breaks the whole Law, though not the whole of the Law; as he that wounds a Man's Arm, wounds the whole Man, though not the whole of the Man; he that breaks one link breaks the whole Chain, and he that fails in one Musical Note, spoils the whole Harmony. 2. He sins against Charity, which is the summ of the Law, and upon which all the Commands depend; and so though he keep most of them, as to the substance, yet he keeps none of them in a right manner, because none out of Love, which should be the Principle out of which he observes all of them. 3. He sins against the Authority of the whole Law, which is the same in every Command. 4. He is liable to the same punishment, though not the same degree of it as if he had broke all the Commandments, Gal. 3.1. and his keeping most, cannot exempt him from the punishment due for the breach of that one; this he speaks either in opposition to the Pharisees among the Iews, who thought themselves righteous if they kept most of the Law, though in some things they came short; or, rather against Hypocrites among Christians, who would pick and chuse Duties, obey some Commands and neglect others; whereas no obedience to God is right, but that which is impartial and respects all the Commands, Psal. 119.6. Matth. 5.19.
