Similarity And Difference

Τίς ὁ μετασχὼν παραπλησίως ἡμῖν αἵματος καὶ σαρκός; ἄνθρωπος γὰρ ψιλὸς σὰρξ καὶ αἵμα τυγχάνων, οὐ μετέχειν λέγεται σαρκὸς καὶ αἵματος· εἰ κατὰ πάντα ἡμῖν ὡμοιώθη, τίς ὁ ὁμοιωθείς; Τὸ γὰρ πᾶσιν ὁμοιούμενον, εἴναι πάντως ἀνάγκῃ διαφορον. Άγιος Ιωάννης ο Δαμασκηνός, Κατὰ τῆς Αἱρεσεως Των Νεστοριανών Source: Migne PG 95.189d-192a

Who is He who: 'participating in flesh and blood, was made similar to us?' 1 For man alone is just flesh and blood and is not said to 'participate' in flesh and blood. If He was made similar to us in everything, 2 who is He who was made similar? For being made similar in all things, it is necessary there was quite some difference. Saint John of Damascus, Against the Nestorian Heretics. 1 Heb 2.14 2 Heb 4.15
