This is a split from here
No Christian that subscribes to the Confession of Chalcedon (99% or more of all Christians) believes what you propose (the part I have colored in read and particularly the part I have underlined). All consider what you have proposed "His human ousia being added to His divine ousia" to be heresy. Allow me to explain your error...
Below I've quoted the Chalcedon belief for you to examine and reappraise your imaginative invention... Maybe you have simply confused yourself with the terminology...
By definition "ousia" is unchangeable, so the Son could not add a human ousia to his divene ousia as you propose. Ousia is the absolute definition of a category of things - what they are!!! Change the definition and you have something entirely different - a new category of thing - in your case some kind of hybrid.
An ousia (essence) is an attribute/property possessed by a hypostasis (person as a concrete reality). A hypostasis can have attributes/properties added to it. Thus Chalcedon belief holds that the Son (a hypostasis) via Mary (another hypostasis) acquired humanity. Thus the Son retains two ousia, or more particularly is perceived to have two observable natures (duo physes). Physis/es are the terms used at Chalcedon. Basically physis is what proves an ousia. Unlike ousia which can be determined from metaphysical speculation, a physis has observable motion/activity and it is this motion/activity that proves an ousia.
The Confession of Chalcedon
We, then, following the holy Fathers, all with one consent, teach people to confess one and the same Son, our Lord Jesus Christ, the same perfect in Godhead and also perfect in manhood; truly God and truly man, of a reasonable [rational] soul and body; consubstantial [co-essential] with the Father according to the Godhead, and consubstantial with us according to the Manhood; in all things like unto us, without sin; begotten before all ages of the Father according to the Godhead, and in these latter days, for us and for our salvation, born of the Virgin Mary, the Mother of God, according to the Manhood; one and the same Christ, Son, Lord, only begotten, to be acknowledged in two natures, inconfusedly, unchangeably, indivisibly, inseparably; (ἐν δύο φύσεσιν
