Colossians 1 · 15–20

the cosmic Christ hymn

Strophe One · Cosmic Creation

He is the image of the invisible God,εἰκὼν τοῦ θεοῦ τοῦ ἀοράτου the firstborn of all creation.πρωτότοκος πάσης κτίσεως

For in him all things1 were createdἐν αὐτῷ ἐκτίσθη τὰ πάντα in the heavens and on the earth, things visible and invisible, whether thrones or powers or rulers or authorities —θρόνοι · κυριότητες · ἀρχαί · ἐξουσίαι all things2 have been created through him and for him.δι' αὐτοῦ καὶ εἰς αὐτόν

And he is before all things,πρὸ πάντων · anarthrous and in him all things3 hold together.συνέστηκεν · perfect tense

Strophe Two · New Creation

And he is the head of the body, the church.κεφαλὴ τοῦ σώματος, τῆς ἐκκλησίας He is the beginning,ἀρχή the firstborn from the dead,πρωτότοκος ἐκ τῶν νεκρῶν so that he might have first place in all things.ἐν πᾶσιν αὐτὸς πρωτεύων · anarthrous

For in him God was pleasedεὐδόκησεν that all of the fullness would dwell,πᾶν τὸ πλήρωμα κατοικῆσαι and through him to reconcile all things4 to himself,ἀποκαταλλάξαι · Pauline coinage things on earth and things in heaven, having made peace through the blood of his cross.εἰρηνοποιήσας διὰ τοῦ αἵματος τοῦ σταυροῦ αὐτοῦ

τὰ πάντα
— articular "all things" refrain × 4 (v. 16 ×2, v. 17, v. 20). Two anarthrous πᾶς-forms — πρὸ πάντων (v. 17) and ἐν πᾶσιν (v. 18) — echo the saturation but lie outside the strict refrain.
merism
— heaven/earth, visible/invisible (inclusio: v. 16 ↔ v. 20)
