Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
Can someone answer me a question : how is it orthodox to say the Divinity of Christ is a person which is given "birth" to when in fact God is not a "person"? How can we speak of a Spirit as something which is given birth to when it is not subject to the physical world, when it is immortal and in the case of God without beginning ? Would it not be much more orthodox to say that the Virgin gave birth to the humanity of Christ which was subject to the things implied by birth ?
Perhaps you should dive a bit deeper into the Patristic writings and sprinkle this with some Hindu theological texts which can perhaps animate and give a more detailed language to help understand and describe that which can not be described. As Jesus Christ told us, "If I tell you physical things and you can not understand, how will you be understanding when I tell you spiritual things?"
It is fundamental that we understand the doctrine of the Incarnation in the Orthodox concept, that Jesus Christ is mutually and eternally a human being and God. He is not a God who became a man, He is not a man who became a God. He was always a God, and always a Man, perfect God and perfect Man, Two Natures FROM One Person, and that unified person of Jesus Christ is both God and Man, in perfect hypostasis. This is not necessarily easy to understand, but here is a Patristic analogy. In purely scientific terms, Adam is the first sequence of purely homo sapien DNA, and Eve is that mother of us all who we share the exact same mitochondrial DNA. Jesus Christ's humanity always followed this same pattern of Adam's DNA, and this is the mathematical concept of His humanity, that He shares our own DNA and subsequent physicality.Some of the Hindu mystics have wonderful dialogue explaining in poetry and symbolism the idea of humanity itself being a condensate of the Divine Source. In Hinduism, ALL human beings are like Jesus Christ, a composite mix perfectly of the Divine and the Human forms. While that is not specifically the Orthodox doctrine, the language and manner in which the Hindus explain this can serve usefully to explain our own Orthodox concept of the Incarnation.
The Father is the Sun (ie, the origin/source), the Son is the Light (ie, the material manifestation of the Essence of the Origin) and the Holy Spirit is the Heat (ie, the reaction to the Origin)
Jesus Christ's Divinity is the fire, and His Humanity is the heat (ie, the manifestation of this fire), but its in unison, just as you can not take away the heat from the fire in nature. In Ethiopian Orthodox we call this Tewahedo (literally, "Made into one, composite form") which is both a concept and a word derived from the Hebrew "ahkhad" ("made-one from many") which is exactly the term used by Jesus Christ and Moses when they said and quoted, "Hear O Israel, the Lord your God is ONE (ie, made into one) God."
(from the Strong's Concordance/Lexicon)
In the Virgin Mary, the humanness of Jesus Christ condensed in Her own purely human flesh and became God-Man, as His Divinity was always from the Father, before the beginning, and His humanity also always existed, in fact He is the origin of all humanity. When God created Man, He created ALL mankind in the proto-type of Adam, and we are also of this same origin. This is also part of the concept of the Body of Christ which is taught in the Epistles and the Patristic writings, but a bit more obscurely and mystically explained.
