I agree A...sorry for the misunderstanding.
I see see the Church “as we know it today” in the OT.
I do it see having begun with Abraham as the covenant people of God, and that we Gentiles are grafted into that natural olive tree, whereby the root supports us all.
The “New” covenant is the restored or refreshed covenant, which flows with the original meaning of “I am building and restoring” from Matthew.
Abraham made covenant with Christ, and had the Spirit of Christ within Him.
He belongs to Christ the way we are today.
He was justified by faith, looking forward to the cross, as we are justified by faith looking back.
The New (Refreshed) Covenant is indeed a better covenant based on better promises, however that doesn’t mean it’s a brand new different covenant.
Christ has redeemed us from the curse of the law, having become a curse for us (for it is written, “Cursed is everyone who hangs on a tree”), that the blessing of Abraham might come upon the Gentiles in Christ Jesus, that we might receive the promise of the Spirit through faith. Galatians 3:13-14
- that the blessing of Abraham might come upon the Gentiles in Christ Jesus, that we might receive the promise of the Spirit through faith.
