150On ἀϰϱογωνιαῖος (which is an adjective qualifying λίθος, whether that substantive is expressed or not) the Patristic Greek Lexicon (ed. G. W. H. Lampe) comments: ”(stone) as topmost angle or point of pyramid, obelisk, etc., which being cut out before being set in position, and being last laid, would not fit if construction were not true.” See, however, R. J. McKelvey, “Christ the Cornerstone,” NTS 8 (1961-62), 352-59, in defense of the meaning Grundstein.
151Of the “capital” of a column (Heb. kōṯereṯ), three times in one verse.
152Heb. leō’š pinnāh (LXX εỉς ϰεφαλὴν γωνίας).
153Isa. 8:14-15 and 28:16 are conflated in Rom. 9:32-33. In Luke 20:17-18 the rejected stone which became head of the corner (cf. Mark 12:10-11) is conflated not only with the rock of stumbling of Isa. 8:14-15 but also with the stone of Nebuchadnezzar’s dream (Dan. 2:34-35). A conflation of Isa. 28:16 with Ps. 118 (LXX 117): 22 appears in the Naassene exposition quoted by Hippolytus (Ref. 5.7.35-36), where Adamas, the heavenly man (cf. p. 299 with n. 125), is described as “the corner stone which has become head of the corner.” H. Schlier (Christus und die Kirche im Epheserbrief, pp. 47-48) looked to this exposition for a background to Eph. 2:19-21, but there is no good reason for assigning a pre-Christian date to this exposition or to an earlier stage of gnostic speculation supposed to underlie both it and the Mandaean doctrine of the “secret Adam.” If a background be sought for the present application of Isa. 28:16 the application quoted above from 1QS 8.7-8 is a stronger candidate.
154A better rendering of ἀϰϱογωνιαῖος than “foundation-stone.” (In the same marginal note “the foundation of the apostles and prophets” is given as an alternative to “the foundation laid by the apostles and prophets.”)
