That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:
to be put into effect when the times reach their fulfillment — to bring unity to all things in heaven and on earth under Christ.
εἰς οἰκονομίαν τοῦ πληρώματος τῶν καιρῶν, ἀνακεφαλαιώσασθαι τὰ πάντα ἐν τῷ Χριστῷ, τὰ ἐπὶ τοῖς οὐρανοῖς καὶ τὰ ἐπὶ τῆς γῆς·
eis oikonomian toy plērōmatos tōn kairōn, anakephalaiōsasthai ta panta en tō Christō, ta epi tois oyranois kai ta epi tēs gēs·
