This would suggest the Fall was pre-determined.
I prefer a more Patristic perspective, at least based on many ideas I’ve been exposed to–to find more robust patristic sources I’d have to do a deep dive. Adam and Eve were not created “perfect” per se, but were created in a state of potential to grow. To clarify that previous statement, I’m not suggesting they were created sinful, that isn’t how I’m using “perfect” here; I’m using it in a more basic sense of not-yet complete. There was room for Adam and Eve to grow, in much the same way a child has yet the potential to grow, to mature. That God intended humanity to grow, through knowledge and relationship with Him.
The Fall is a fracture–Adam and Eve, like disobedient children or rebellious teenagers, chose to do things their way, tempted by the serpent’s deceit they “rushed” to adulthood, to “know good and evil” and “be as gods”. God always intended that Adam and Eve grow into maturity by knowing Him, and to grow to be more like Him.
They did know right and wrong; they knew what God commanded, “You may partake of the fruit of every tree in the garden, but the fruit of the tree of the knowledge of good and evil you may not partake of”–the command was given to Adam, and Eve knew the command. Yet Eve took of the fruit, and Adam did too–and like children caught with their hands in the cookie jar, they tried to blame everyone but themselves.
A maturing knowledge of God would also mean to know God in His holiness–in His rightteousness, His goodness, His fullness of Himself; but they went another route, one that was disobedient.
Christ, as the New Man, the Second Adam, undoing Adam’s wrong by His righteous obedience, establishes Himself as a restoration of the fullness of being human.
There is one opinion, that the Incarnation is only necessitated by the Fall, in order that God in becoming flesh should, by His death and resurrection, make right what was wrong. While there is another opinion which is possible: The Incarnation was always intended, the Fall did not create the necessity for the Incarnation–but the necessity of Atonement; it was always, in this view, God’s intention for the Incarnation, and that Adam and Eve–all humanity–ought to grow and come to a greater knowledge and love of God through God’s own willful participation in human nature and His own creation. The Fall was not, then, an interuption; but a condition which needed addressing; and God addresses it in the Incarnation–but the Incarnation establishes the eternal reality that was always supposed to be.
So when we behold the full restoration and renewal of all things in the future Ages of Ages, Christ is still in the center of everything. The Incarnation always, and was always, supposed to be the pillar of everything God intended for creation, “All things were made by Him and for Him”, and it is here, in Christ, that we are fully human as God intended, and in the end–in Christ–we are fully clothed with God’s glory, even as God, in Christ, is fully clothed with our humanity. So in Christ there is the unity of God and man: literally in that He is the one and only God-Man; and also in that in Him we are fully reconciled to the Father; but also in that we only truly know and love and experience God in and through Him. He is the Radiance of God’s Glory, the Image of the Invisible God, to know Him is to know the Father: The Father has always willed to be known only by His Son, and the Son always makes His Father known. In Christ is the reconciliation, the renewal, the healing, the salvation, and the fullness of creation and the fullness of Deity. He is the God-Man.
