“In illâ veluti humilitate seminis esse magnitudinem Nominis.” [The promise (Gen. iii. 15) dignified the loins of Isaac (Gen. xvii. 19) as with the Incarnation in its germ. Hence this mysterious form of oath was an oath by the Promised Seed (Gal. iii. 16). St. Paul quotes “the promises” (not one text only), and honours the Septuagint, which gives what he makes so emphatic in Gen. xii. 7, xv. 18, and xxii. 18.—C.]
