[Kolokotronis]

"Well, actually, maybe not, because where would His other 50% come from? There was no human male involved.

But at any rate, we are not just bodies but body-soul combinations, so whatever Mary contributed to the body of Christ, His human soul and divinity certainly did not come from her."

The Nicene Fathers explained this nearly 1700 years ago, Claud (I'm not showing off; the Greek is important to an understanding of what happened):

καὶ εἰς ἕνα Κύριον Ἰησοῦν Χριστὸν τὸν υἱὸν τοῦ Θεοῦ τὸν Μονογενῆ, τὸν ἐκ τοῦ Πατρὸς γεννηθέντα πρὸ πάντων τῶν αἰώνων, Φῶς ἐκ Φωτός, Θεὸν ἀληθινὸν ἐκ Θεοῦ ἀληθινοῦ, γεννηθέντα οὐ ποιηθέντα, ὁμοούσιον τῷ Πατρί, δι' οὗ τὰ πάντα ἐγένετο· τὸν δι' ἡμᾶς τοὺς ἀνθρώπους καὶ διὰ τὴν ἡμετέραν σωτηρίαν κατελθόντα ἐκ τῶν οὐρανῶν, καὶ σαρκωθέντα ἐκ Πνεύματος Ἁγίου καὶ Μαρίας τῆς παρθένου, καὶ ἐνανθρωπήσαντα,

The specific answer to what the Theotokos "added" is this, but only also from the Holy Spirit:

καὶ σαρκωθέντα ἐκ Πνεύματος Ἁγίου καὶ Μαρίας τῆς παρθένου, καὶ ἐνανθρωπήσαντα

It's all Greek to me. How about a translation?

Kolo, my apologies, but my Greek is not nearly good enough to parse that paragraph...could I trouble you for a translation at least of the key sentence?

Something about the body coming from the Holy Spirit *and* the Virgin Mary?

Enanthroposanta is also throwing me for a loop. :)
