Neo-Calvinists share with theonomists a post-millennial outlook. David Koyzis illustrates:
Yet the call to holiness and to living for the kingdom is as extensive as creation itself. Farmers, manufacturers, labour union stewards, musicians, artists, journalists, electricians and sewage line workers are not obviously preaching the gospel or attempting social reform. Yet if they are in Christ, they are agents of his kingdom in every walk of life.
It is telling that the authors of the statement neglect the eschatological dimension of the faith. Eschatology, or the doctrine of the last things, is not a mere add-on to our Christian walk. Rather, it gives us direction for the future. At the end of the present age are we to be removed from this world to spend eternity in a blissful ethereal realm of floating spirits? Or will the whole creation be renewed when Christ returns? Perhaps the authors are not in agreement on this, which could account for their silence. Nevertheless, the Bible itself is not so reticent: “For we know that the whole creation has been groaning together in the pains of childbirth until now. And not only the creation, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption as sons, the redemption of our bodies” (Romans 8:22-24). “For in him [Jesus Christ] all the fullness of God was pleased to dwell, and through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross” (Colossians 1:19-20). “And he who sat upon the throne said, ‘Behold, I make all things new'” (Revelation 21:5, emphases mine).
We live in the hope of the resurrection of the dead in a renewed creation, which awaits its final fulfilment at Christ’s return. In the meantime we are heirs of this promise in everything we do in God’s world.
That quotation has the classic marks of neo-Calvinism, a view of the kingdom of God that blurs distinctions between holy and ordinary vocations, between church and secular matters, regards growth in holiness as something that applies to non-Christian affairs. Above all, the classic way of seeing continuity between this world and the world to come.
Neo-Calvinism is especially defective about the nature of the saeculum, which is the age between the advents of Christ. Greenbaggins invoked Vos to explain the peculiar character of the period when the ministry of word and sacrament defines the church, in the words of the Confession of Faith, as “the kingdom of the Lord Jesus Christ, the house and family of God” (which means the kingdom of Jesus is not Hollywood, New York City, Grand Rapids, or the Department of Health and Human Services:
Here is Vos (a Dutch Calvinist, mind you):
The significance of the unique organization of Israel can be rightly measured only by remembering that the theocracy typified nothing short of the perfected kingdom of god, the consummate state of Heaven. In this ideal state there will be no longer any place for the distinction between church and state. The former will have absorbed the latter.
In other words, the present state of distinction between church and state is a parenthesis. One day in the future, a perfect theocracy (with no possibility of the people’s apostasy) will come into being in its fully ineradicable, eschatologically perfect state.
That parenthesis, the interadvental period, is the age of the secular. It is the time when church and state are distinct, when Christ’s reign as king is divided between ruling creation and reigning over the redeemed.
Those who deny that distinction, those who see a progression from Israel (good), to church (better), to glory (best) fail to acknowledge the difference that the interadvental period makes. It is a time when all efforts to immanentize the eschaton, either by bringing the past (Israel) into the present, or bringing the future (new heavens and new earth) into the now, are flawed because Jesus’ spiritual kingdom is not of this world.
