Ephesians 3:21

αὐτῷ ἡ δόξα. ‘His is,’ or ‘To Him be’ the glory. The acknowledgement of the fact is perhaps stronger than the prayer for its recognition by men. Cf. the liturgical conclusion to the Lord’s Prayer, ‘Thine is the kingdom &c.’

ἐν τῇ ἐκκλησίᾳ, cf. Ephesians 3:10, διὰ τῆς ἑκκλησίας. The ‘glory’ has its permanent home on earth in the Church as the shrine of the Spirit.

καὶ ἐν Χ. Ἰη. In Jude 1:25; Romans 16:27, we have διἀ Ἰ. Χ., Jesus Christ being regarded as our High Priest and presenting our praises to the Father. Here ‘the glory’ dwells in Him and is manifested in Him to men. Note the recurrence of both forms in 2 Corinthians 1:20, and cf. 2 Corinthians 4:6; Philippians 4:19.

εἰς πάσας τἀς γενεὰς τοῦ αἰῶνος τῶν αἰώνων. Each age is composed of many generations. St Paul’s language here suggests the conception of an age, the constituent parts of which are not generations only but each a complete age. There is no exact parallel.
