There was a debate, very recently, between Dr. James White and Dr. Leighton Flowers with reference to John 6:44-45. The theological locus under disputation was on the 
Calvinist doctrines of unconditional election and the effectual call. White argued the positive position, i.e., affirming unconditional election and the effectual call; whilst Flowers argued the negative, i.e., denying unconditional election and the effectual call. For the purposes of this post, I am just going to assume the reader understands the entailments of said doctrines, and cut right to the chase in offering the Athanasian Reformed (AR) (Evangelical Calvinist) reading of John 6:44-45. I believe it is the better more theologically acute way one must exegete John 6:44-45, among many other passages, in light of Christological orthodoxy. In other words, I will suggest (not argue here) that everyone reads the text of Scripture through theological lenses; and since that’s the case, it is best to exegete Scripture from good theological premises, rather than bad ones. I would simply assert here that both White and Flowers, respectively, offer a reading of John 6 that are based on bad theological premises.
Here is the passage in the English translation (NASB95):
44 No one can come to Me unless the Father who sent Me draws him; and I will raise him up on the last day. 45 It is written in the prophets, ‘And they shall all be taught of God.’ Everyone who has heard and learned from the Father, comes to Me.
White argues that all who are drawn of God will necessarily come to God (so, what he takes to be a prima facie argument for unconditional election vis-à-vis the effectual call). Flowers argues that the drawn ones who come to God are those who have not only heard, but have actively learned from the Father, and through this, said drawn ones freely choose to come to God based on their innate human freedom to do so (he believes the capacity comes, situationally, as people hear the call and learn from God of His way for them; but this based on an ontic capacity built into the human agent to accept or reject the call of God). So, in nuce, we can see how White clearly is thinking from the typical Calvinist emphasis on God’s sovereignty, and how Flowers, respectively, ends up emphasizing the human agents’ intact libertarian freewill to say yes or no to God’s offer of salvation.
The Athanasian Reformed alternative sees the eternal Son of God, as both the electing God and elected (archetypal) human for all of humanity. So, we can affirm unconditional election and the effectual call, but only under radically reified terms. So, for the AR, we maintain that what does the necessary work here, theologically, is a robust affirmation of a doctrine of the vicarious humanity of Christ (which is really just the Chalcedonian and Nicene understanding of the homoousious; i.e., that Jesus is both fully God and fully human in His singular person as the Christ). In this sense, the eternal Logos is both ‘unconditionally elect’ and ‘effectually called’ insofar that He freely chooses to become us that we might become Him by the grace of adoption (think of II Cor. 8:9 and the mirifica commutatio ‘wonderful exchange’). In this frame, Christ, God’s personal grace for the world, from within the triune Life, as the mediator between God and humanity, as our High Priest, enters into the sinful reprobate status all of humanity is born into; putting it to death at the cross; and rising anew as God’s humanity for the world, the second and greater Adam, the ‘firstborn from the dead,’ God’s ‘firstfruits,’ whereby humanity, in Christ’s humanity, the only genuine humanity coram Deo (before God) has been truly humanized in and from the humanizing humanity of Jesus Christ. As He, in His vicarious humanity said Yes to the Father for us, we by a correspondence of His faith, by the same Spirit’s breath now have the freedom of God to say yes and amen to God, acknowledging all that God has provided for us in His salvation for all of humanity (which is first His humanity for us).
So, for the AR, total depravity/total inability, to use those terms, is indeed a real problem for a humanity incurved upon itself (homo incurvatus in se). But what is different for AR is that on the one hand grace isn’t an abstract quality given to the elect, like created grace is, as maintained by the classical Calvinists (like White); on the other hand, grace, and being unilaterally placed into God’s grace is a necessity if fallen humanity is going to have the capacity to indeed seek God and receive His salvation for them. Further, contra the Arminian, or Flowers’ so-called provisionism, fallen humanity, again, is in need of God’s unilateral movement of placing us into His re-created and elect life in Christ, if in fact we are going to be able to speak of a genuine human freedom. So, against the Provisionists, AR maintains that in order to be truly human before God, that is to have genuine human freedom for God, that that must first be provided for all of humanity in and through God’s disruptive gracious humanity as that penetrates our dead humanity, giving us a new and real human life in His.
Hence, God’s unconditional election is inclusive of all of humanity, since the only humanity to be assumed in the incarnation was the fallen humanity. Jesus was “effectually called” (and I put that in quotes because AR does not affirm the Aristotelian causal theory that classical Calvinists do), freely coming for us, taking all of humanity with Him, as the second Adam, to the right hand of the Father. Why all of humanity does not finally affirm God’s election for us in Christ, seeing that all of the conditions for salvation have already been fully actualized in God’s humanity for the world, remains an aspect of the surd-like and inscrutable mystery of sin. All are elect in Christ, but not all finally come. We know why people do come, but sin keeps us in the dark in regard to why some don’t ultimately repent and acknowledge what God has already done, provided, and actualized for them in the real humanity of Christ.
In closing, with reference to John 6 and its grammar: verse 44 says, “No one can come to Me unless the Father who sent Me draws him.” Here, the doubly consubstantial life of Jesus, who is both the eternal Son, who is fully God, and who is also fully human, is theologically present in this clause. That is to say, in the analogy of the incarnation, the ‘Me’ and the ‘Father’ (insofar as the person and works of God are indivisible) are in reference to God’s life, and at the same time, in reference to God’s life of salvation actualized for the world in the man from Nazareth, Jesus Christ. Theologically the “draws him,” with reference to the ‘him,’ remains in the singular, insofar that the [hu]man who was first drawn of God, was God’s particular humanity for the world in Jesus Christ. He will indeed be “raised up on the last day” whereby every knee will bow and every tongue confess that Jesus Christ is Lord; and all of humanity, all of those who have repented, out of Christ’s repentance for us, will be exalted in consummate form with Him as the new creations we have become as participants in Christ’s new and resurrected humanity for us.
In a canonical way it is fitting then to close this post with reference to another Apostle, Paul:
May it never be! How shall we who died to sin still live in it? 3 Or do you not know that all of us who have been baptized into Christ Jesus have been baptized into His death? 4 Therefore we have been buried with Him through baptism into death, so that as Christ was raised from the dead through the glory of the Father, so we too might walk in newness of life. 5 For if we have become united with Him in the likeness of His death, certainly we shall also be in the likeness of His resurrection, 6 knowing this, that our old self was crucified with Him, in order that our body of sin might be done away with, so that we would no longer be slaves to sin; 7 for he who has died is freed from sin. -Romans 6:1-7
What we have been referring to as election and the vicarious humanity of Christ also finds biblical reference to Paul’s theological motif of ‘in Christ’ theology. It is really a doctrine of union with Christ that we are concerned with, and what is the entailment of a proper doctrine of pre-destination and election; insofar that what salvation involves first involves God’s choice to be for us in the humanity of Jesus Christ. And this free election of God’s becomes what we grammatically call the hypostatic union wherein God and humanity are united as God becomes humanity that we might become partakers of the divine nature in and through the person of Jesus Christ. But you see then how this involves a doctrine of unio cum Christo (union with Christ).
