But when it says [citing Ps. 8.6] "All things are put in subjection," it is plain that this does not include the one one who put all things in subjection under him"
"When all things are subjected to him, then the Son himself will also be subjected to the one who put all things in subjection under him, so that God may be all in all.
To say that Christ rose again in "accordance with the scriptures" is at its heart a statement about God's long-range plans, with Christ, on our behalf, as this has been set forth in scripture. To quote Seitz:
"It is not that a straight line moves from the Old Testament to Christ in some mechanical fashion. Rather, we comprehend what God is doing in Christ right now and to eternity by returning to the Old Testament and seeking to find within its manifold testamony accordance with what we are coming to know about God in Christ. Once again we are brought up against the reality that the Old Testament, as Christian scripture, is not just before Jesus, but after him as well. It is both B.C and A.D., because Jesus lives in relationship to the Father, to Israel, and to the world; and the Father has set forth his broader plans for the world in his word to Israel, plans at whose center stands Christ. For an understanding of Christ's present rule and relationship to God, from the moment of God's raising him from the dead to that final point when God is all in all, it was necessary to search a first testament to learn about last things." (Seitz, 1998: 57)
