Christ as Last Adam

One of my classes this semester is all about the work of Christ. Obviously, this has caused me to do some major reflection on all the many beautiful facets of the cross-work of our Lord. The substitutionary nature of the atonement has been under attack of late from all kinds of critics, both within and without evangelicalism. There have been many able responses affirming penal substitution. In my opinion, this has caused evangelicals to neglect the other aspects of the atonement. Can you think of a good Calvinistic work on the Christus Victor theme (Christ's victory over the principalities and powers)? For my paper, I wanted to focus in on some neglected aspect. Here is the bare-bones outline of my 24 page paper:

I. Eschatology
Eschatology is not simply the study of last things. A better definition is "the direction and goal of God’s active covenant faithfulness in and for His created order” (Brower). It is not an exaggeration to say that eschatology is the heart of the Bible, starting in Gen. 3.15. All that the prophets looked forward to has come with the first coming of Jesus Christ. They did not realize that the Messiah would have 2 comings. Christ's life, death, and resurrection ushered in the last days (Heb 1.2, 1 Cor 10.11, Gal 4.4, etc).

I. Adam
--A. The Old Creation
Adam is the head of the old creaion. He is given dominion, and called to represent YHWH as his divine image (Gen 1.26-28).
--B. Adam as Image/Son
The ancient near Eastern context would have been familiar with 'image' terminology. When a king conquered an area, he'd set up an image. The king was considered the image of a god. He represented the god on earth. When anyone saw the image, they would recognize that a certain king representing a certain god, had conquered and ruled that area. God is making a statement in creating humanity in his image. Humans cover the whole earth. God is saying that he rules and owns the whole universe. Humans are to represent YHWH's rule on earth.
Image is also tied to Sonship, so that Adam can be called the son of God (Gen 5.1-3, Luke 3.38).
--C. Edenic Cov.
Adam was head of the creation, as the covenantal head. In creating, God made a covenant with his creation. This is clear from the language used when God confirms the covenant made with Noah (Also see Hos 6.7, Jer 33.19-26, Rom 5.12-21)

II. Christ
--A. Christ as Eschatological Adam
See Rom 5.12-21, 1 Cor 15.21-22, 45-47.
--B. The true and obedient Son
Christ is the true image of God (2 Cor 4.4, Col 1.15). Christ undoes the work of Adam. The phrase “did not count equality with God a thing to be grasped” (Phil 2:6b) hearkens back to Genesis 3:5 (you will be like God) and the temptation of the first image-bearers. While the first Adam attempted to grasp equality with God, the last Adam did not use his equality with God for his own advantage but made himself nothing, for our sake.
The NT attests throughout that Christ is the Son of God. After the geaneology tracing Christ back to Adam (Lk 3), Luke then narrates Christ's temptation in the wilderness. Unlike Adam, Christ is successful in the wilderness. Where Adam failed, Christ is victorious.
--C. New Creation
Christ inaugurated the new creation with his resurrection. Easter morning was the first day of the new order. His work is cosmic in scope, and is renewing the entire creation. His redemption does not stop with individuals. His work will restore us to Eden and beyond.
--D. New Covenant
Christ death and resurrection initiates the new covenant, promised by the prophets. The Mosaic Covenant was only temporary. Christ is the last Adam, true seed of Abraham, new Moses, and David's greater Son. All the covenants find their fulfillment in him.
This new covenant brings with it a new humanity, whose sins are forgiven and are filled with the promised Holy Spirit. Christ is the true Israel, and by virtue of our faith-union with him, we are the true Israel (Gal 6.16, 3.29).
Christ restores his people to true humanity so that we love God, love our neighbor, and are good stewards of the earth. His resurrection is the guarantee of ours, the firstfruits. We are to be a kingdom of priests to the world as we wait for his return when he will return the cosmos to its original intention. We will reign with him in the new heavens and new earth.
