26. Therefore if the uncircumcision keep the . . . law, &c.--Two mistaken interpretations, we think, are given of these words: First, that the case here supposed is an impossible one, and put merely for illustration [HALDANE, CHALMERS, HODGE]; second that it is the case of the heathen who may and do please God when they act, as has been and is done, up to the light of nature [GROTIUS, OLSHAUSEN, &c.]. The first interpretation is, in our judgment, unnatural; the second, opposed to the apostle's own teaching. But the case here put is, we think, such as that of Cornelius (Ac 10:1-48), who, though outside the external pale of God's covenant, yet having come to the knowledge of the truths contained in it, do manifest the grace of the covenant without the seal of it, and exemplify the character and walk of Abraham's children, though not called by the name of Abraham. Thus, this is but another way of announcing that God was about to show the insufficiency of the mere badge of the Abrahamic covenant, by calling from among the Gentiles a seed of Abraham that had never received the seal of circumcision (see on Ga 5:6); and this interpretation is confirmed by all that follows.
