But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors.
Respect of persons violates the command to love all alike "as thyself."
Ye commit [ ergazesthe (G2038 ): work] sin - referring to Matthew 7:23, as James 1:22. Your works are sin, however ye in words boast of the law (note, James 2:8).
Convinced - Old English for 'convicted.'
As transgressors - not merely of some particular command, but of the whole.
