ἀκρογωνιαῖος — akrogōniaîos

ἀκρογωνιαῖος,,, a word wholly Biblical and ecclesiastical (Winer's Grammar, 99 (94); 236 (221)) (ἄκρος extreme, and γωνία corner, angle), placed at the extreme corner; λίθος cornerstone; used of Christ, 1Pe 2:6; Eph 2:20; the Sept. Isa 28:16 for פִּנָּה אֶבֶן. For as the cornerstone holds together two walls, so Christ joins together as Christians, into one body dedicated to God, those who were formerly Jews and Gentiles, Eph 2:20 (yet cf. Meyer at the passage) compared with Eph 2:14; Eph 2:16-19; Eph 2:21 f And as a cornerstone contributes to sustain the edifice, but nevertheless some fall in going around the corner carelessly; so some are built up by the aid of Christ, while others stumbling at Christ perish, 1Pe 2:6-8; see γωνία, a.
