“Reformed covenant theology seems to build its case on three main premises. Firstly, that the old covenant was revoked because Israel so thoroughly violated it (a punitive supersessionism). Secondly, the old covenant was in any event only ever temporary. Thirdly, the efficacy of the old covenant was not actually as Israel took it to be, at face value; rather than dealing with Israel’s transgression (as its practitioners would quite reasonably have supposed at the time) it was instead to remind her of her transgressions and point her to Christ to come.”
