Ephesians 1:1-12 [NIV]
Paul, an apostle of Christ Jesus by the will of God,
To God’s holy people in Ephesus,a d the faithful in Christ Jesus:
2 Grace and peace to you from God our Father and the Lord Jesus Christ.
Praise for Spiritual Blessings in Christ
3 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. 4 For he chose us in him before the creation of the world to be holy and blameless in his sight. In love 5 he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will—6 to the praise of his glorious grace,p which he has freely given us in the One he loves.q 7 In him we have redemption through his blood,s the forgiveness of sins, in accordance with the richest of God’s grace 8 that he lavished on us. With all wisdom and understanding, 9 he made known to us the mysteryu of his will according to his good pleasure, which he purposed in Christ, 10 to be put into effect when the times reach their fulfillment—to bring unity to all things in heaven and on earth under Christ.
11 In him we were also chosen,e having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, 12 in order that we, who were the first to put our hope in Christ, might be for the praise of his glory.a 13 And you also were included in Christ when you heard the message of truth,c the gospel of your salvation. When you believed, you were marked in him with a seal,d the promised Holy Spirit,e 14 who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory.
To read this as being written to one group "the Faithful Saints" of which Paul includes himself, and to read in again as addressed to two distinct groups "us/our" and "you" creates two such radically different messages, that they are NOT the same Gospel!
To imply, as you have, that the promises of EPH 1:3-12 are for Jews in order to fulfill an OT promise to the nation of Israel and should not be applied to Gentiles as a promise for all believers is not a trivial point to make. Your claim amounts to one that Jewish Christians are
"
blessed in the heavenly realms with every spiritual blessing in Christ" ... Gentile Christians need to look elsewhere for such a promise (if it exists). Jewish Christians were "
chose in him before the creation of the world to be holy and blameless in his sight." ... Gentile Christians need to look elsewhere for such a promise (if it exists). Jewish Christians were
"predestined for adoption to sonship through Jesus Christ" ... Gentile Christians need to look elsewhere for such a promise (if it exists). Jewish Christians
have "redemption through his blood, the forgiveness of sins" ... Gentile Christians need to look elsewhere for such a promise (if it exists).
Gentile Christians were
"marked with a seal, the promised Holy Spirit" ... Jewish Christians need to look elsewhere for such a promise (if it exists).
This is not the tone of the message of the rest of scripture and is very different than the meaning derived from Paul addressing one group in which Greek and Jew become a trivial detail and the promises are for the True (spiritual) Israel, not those who are Jews in flesh only. This may not be your intent, but this is how your words ARE being heard and why they are encountering so much resistance.
*****
Respectfully, we are reading it. Perhaps too closely, but we are reading it ...
I may have misunderstood, but I read you claiming Ephesians 1 is ...
1. about historic Israel (not spiritual Israel)
2. about promises to David
3. not about Gentiles being included in the the promises (you were refuting Nathan making that very point).
4. not about "chosen to be saved".
In my opinion, while Ephesians 1 is about the fulfillment of the promises to Eve and Abraham and David, it appears to me to be ALL ABOUT the Spiritual Israel, the children of Abraham by faith, those with circumcised hearts. It is about the natural branches that were not cut off and the wild branches grafted on all of which derive value and life from connection to the True Vine. The WE/US of Ephesians includes Paul (who was not a gentile but is part of the Faithful Saints, and the YOU of Ephesus excludes Paul (because the statement does not apply to him). There is no division of the body in the lesson or promise, just acknowledgement of the reality ... Paul was not a gentile from Ephesus.
