Christ was made perfectly wholly God, wholly Man. To become like us is essential in the Incarnation to unite Himself to us with his divinity and humanity as only He can do. If we are continually growing, evolving, in a state of flux and each day is but a journey toward becoming something more evolved, then the Incarnation is, in many ways, insufficient. If humanity exists another 500,000 years and we theoretically continue to evolve, Christ will be united to a former type of hominid. This is folly.
We see in Genesis and the entire arc of the Scripture that God made Man in His own Divine Image. God made it, and says it is good. Nothing about man is lacking or sinful, sick or diseased, changing or faulty. No need for anything except to walk in the garden with God and grow toward theosis. Death doesn't exist. Only LIFE! Then the sin, the great sin of Adam and Eve creates death, introduces this scourge into the matrix of ALL CREATION, not just man! Everything is turned upside down and profoundly affected. Death reigns and rears its ugly head. God allows death as a concession, the Fathers tell us, so that our sin isn't immortalized in the fruit of the second tree.
So with Christianity we see nothing but life, perfection, joy, peace, and love, then death is introduced.
With evolution, death is apparent, inherent, and mankind starts as a simple life form that steadily grows through one incarnation after another. At what point do these ape-like hominids become the "Man" that God created and wanted? At what point do all these 'other' hominids die off and there are only two first parents?
Why would God create a chaotic adaptation-driven steady violent, death-laden, evolved ape and allow thousands and thousands of them to die and compete and wipe each other out only to allow two of them to "WAM!" become humans in the garden. So let me get this straight---there was death, then only life, then death again?
Is Creation nothing but "mutation, it is the key to our development" X-Men comic/film or is it what the Holy Spirit breathed to us in Scripture?
Man was "good." He was made "good." He knew no death. To accept evolution really throws the Fathers, the Scriptures, and the profound theology of the ancient Church on its head. Trying to create an unholy matrimony of modern atheist-driven secular scientism and the pious, timeless beauty of Christianity is dangerous if you ask me. Just this Orthodox Christian's two cents....or fifty!
