11 Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands;
OK. Saul is talking about proselytes and God-Fearers.
12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
Eph 2:11–12.
This "covenant of promise" does not refer to any of the Jewish covenants. The word "promise" merely means an "announcement" or "assurance." The word is "epangelia" and it is compound closely resembling the Greek word for "evangelist." So, what is a covenant/contract of announcement? This surely differs from anything that is a covenant such as Abrahamic and Mosaic or New Covenant. And Saul connects nothing to any of the Jewish covenants. He's not even talking about the Jewish covenants.
13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
14 For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; 15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;
Eph 2:12–15.
As you can see there is no mention of any of the Jewish covenants. But Saul does say that we are made IN CHRIST, or in the spirit. not two but one new man. This has nothing to do with any of the Jewish covenants and Saul, being a rabbi who knows the Hebrew Scriptures knows that by being a Christian makes us one with Christ not one with the Jewish covenants. You have to stay in context. Adding to the bible things that are not there Proverbs 30:6 says makes you a liar. So, stop lying. Stop adding to the bible things that are not there. But wait. I know Constantinian Gentile indoctrination pushes you to that end because of the false theology it has developed within itself, and it does that because once Gentiles unmoored true, biblical Christianity from its Hebrew roots it became a new and different religion that has no connection to the God of Abraham, Isaac, and Jacob. All Hebrew Scripture is only understood and re-interpreted with a Gentile mindset and culture that is far removed from Hebrew history and culture it is difficult to understand Hebrew Scripture and history and culture without a Jewish mindset. This only leads to error and heresy.
