Tiago 2:9

9 But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors.

Ver. 9. Ye commit sin ] That is flat; though ye have thought otherwise. See Trapp on " Jam 2:4 "

And are convinced of the law as transgressors ] This they held either no sin or a small one, a peccadillo. The Civilian indeed saith, De minutis non curat lex, the law makes no matter of small matters. But God’s law condemneth small faults: as the sunshine showeth us atoms, moths.
