Jordan Daniel Wood recently shared this Maximian hymn (that’s how I, meditatively, receive it).
JDW then interprets Maximus:
To be crystal clear, "this" refers to the "mystery" he just described:
“In this passage of Scripture, the mystery of Christ is itself called ‘Christ,’ and the great Apostle clearly bears witness to this when he says that ‘the mystery hidden from the ages and the generations has now been manifested’ [Col. 1.26],’ identifying the ‘mystery of Christ’ with ‘Christ’ Himself.
This mystery is obviously the ineffable and incomprehensible union according to hypostasis of divinity and humanity. This union brings humanity into perfect identity, in every way, with divinity, through the principle of hypostasis, and from both humanity and divinity it completes the single composite hypostasis (εἰς ταὐτὸν ἄγουσα τῇ θεότητι κατὰ πάντα τρόπον τῷ τῆς ὑποστάσεως λόγῳ τὴν ἀνθρωπότητα καὶ μίαν ἀμφοτέρων ἀποτελοῦσα..τὴν ὑπόστασιν σύνθετον), without creating any diminishment due to the essential difference of the natures.” (QThal 60.2)
The identity Christ is, is for Maximus the very goal for which all exists, which itself has no higher reason & just so reveals the depths of God's goodness.
My reflection regarding "w/o diminishment due to the essential difference of the natures” follows:
That is to say, for Christ's sake, look beyond (not without) the analogia & abandon your preoccupations with being adopted!
The Trinity thus inverts Joan Osborne to flip the script: "What if YOU were one of us?"
I recall Fr Behr once rhetorically inquiring of JDW- "what work is done by natures in your account?" [paraphrased].
In my view, per manifestation-talk:
It's not that we'll enjoy onto-equality with the Trinity's nondeterminate nature, which we'll only ever "signify." It's just that such an equality with God is truly nothing to be grasped after, even by Jesus!
It's the Son's self-determined nature (humanized divinity) that we (divinized humanity) will progressively "exemplify," together with Him, as that immanent universal aka Totus Christus.
Through Him, With Him & In Him, we'll thereby enjoy, with the Trinity, the identical perichoretic communal delights they’ve shared eternally!
