Ambrosiaster on “works of the law”

I’ve been reading Gerald Bray’s excellent translation of Ambrosiaster’s commentary on Romans and 1-2 Corinthians.

In my reading, Ambrosiaster’s description of works of the law really jumps out at you:

In Rom 3:21, Ambrosiaster defines“law” as “law of the sabbath, the circumcision, the new moon, and revenge.” Then in Rom 3:28 he defines “works of the law” as “circumcision or new moons or the veneration of the sabbath.”

Maybe Jimmy Dunn has been channeling a double portion of the spirit of Ambrosiaster all these years.
