ἀπαύγασμα, ἀπαυγαστος, τό (from ἀπαυγάζω to emit brightness, and this from αὐγή brightness; cf. ἀποσκίασμα, ἀπείκασμα, ἀπεικονισμα, ἀπηχημα), reflected brightness: Christ is called in Hebrews 1:3 ἀπαύγασμα τῆς δόξης ... τοῦ Θεοῦ, inasmuch as he perfectly reflects the majesty of God; so that the same thing is declared here of Christ metaphysically, which he says of himself in an ethical sense in John 12:45 (): ὁ θεωρῶν ἐμέ θεωρεῖ τόν πέμψαντά με. (Wis. 7:26; Philo, mund. opif. § 51; plant. Noë § 12; de concup. § 11; and often in ecclesiastical writings; see more fully in Grimm on Sap., the passage cited, p. 161f) (Some interpreters still adhere to the significant effulgence or radiance (as distinguished from refulgence or reflection), see Kurtz at the passage; Sophocles Lexicon, under the word; Cremer, under the word.)
