Children of Abraham, Not What It Used to Be
All the laws God gave are moral, and the cherry-picking which decides some of them are not moral is a weak instrument used by those who want to ignore the flow of redemptive history, in which not all covenants are the same and in which not all of God’s laws are given at one time.
Beginning in Genesis 12. Abram is promised a great nation (polis), and he can’t have a great nation without land, territory for many people, mostly all biologically related to Abram, a land with no other altars allowed except to Yahweh the King. God also promised blessings for other nations based on their relation to Abram’s nation, with curses for those nations which don’t relate favorably to Abram’s nation.
This is one reason we need to deny that the Abrahamic covenant is the new covenant, despite the continuity between some of the promises to Abraham and the new covenant. Promises to Abraham are fulfilled in the circumcision of Christ on the eighth day (Luke 2).
The sign of circumcision was not only about pointing to the bloody sacrifice of Christ, which cuts the justified elect off from legal solidarity with Adam. Circumcision was an initiation rite for every male in Abraham’s family (even if one parent did not go testify before the presbytery!). And what belonging to Abraham’s family means now and what it meant then is not the same thing.
Theonomists are promising us that, with the right attitude and understanding, we already have what the judiazers offered. But to understand the advance of redemptive history is to see that we don’t need what the judiazers offered, And also, we can’t have what the theonomists are offering. There is only one way now to be children of Abraham, and those who are non-elect and who do not believe the gospel cannot now be “children of Abraham”. They can’t be in the new covenant. Nor should they be in “the administration” of the new covenant.
Now that Christ has been born and circumcised, it’s not possible for jewish male infants to be born as types of the birth to come. The solution to this fact is not to divide the Abrahamic covenants into parts, some cherry-picked as “ceremonial” with other parts “moral”.
Sure, the promises to Abraham are typological. But they put non-Abrahamic people out of the territory to make room for the biological-political heirs of Abraham. And the Doug Wilsons of the world, despite their optimism about future generations being mostly Christians, are no more averse than Augustine and Calvin to pushing people not in their “the church” out of their territory.
If it is not Christ who kept all the conditions of the elect being in (and staying in) the new covenant, then we need to hear a lot more from theonomic folks about the kind of “conditionality” involved in the new covenant. Is the new covenant “unbreakable” only in the sense that the covenant stands even if no individuals do what they have to do to “get connected” (and stay connected) with Christ’s death?
