Well,
No offense intended here, but I actually think it is you that's "mixed up" when it comes to basic Biblical context/hermeneutics. I agree that we are to keep the "unity of the spirit of the Bond of peace". Amen! But just so we aren't picking & choosing verses out of context to support a predetermined suppositional argument however we fancy - what's the surrounding context of that verse?
Ephesians 4
1I therefore, xa prisoner for the Lord, urge you to xwalk in a manner worthy of xthe calling to which you have been called,2with all xhumility and xgentleness, with xpatience, xbearing with one another in love, 3eager to maintain the unity of the Spirit in xthe bond of peace. 4There is xone body and xone Spirit””just as you were called to the one xhope that belongs to your call”” 5xone Lord, xone faith, xone baptism, 6xone God and Father of all, xwho is over all and through all and in all.7But xgrace was given xto each one of us xaccording to the measure of Christ's gift.8Therefore it says,
x"When he ascended on high xhe led a host of captives,
and he gave gifts to men.”
9(xIn saying, "He ascended,” what does it mean but that he had also descended into xthe lower parts of the earth? 10He who descended is the one who also xascended xfar above all the heavens, that he might xfill all things.) 11And xhe gave the xapostles, the prophets, the xevangelists, the xpastors and teachers, 12xto equip the saints for the work of ministry, for xbuilding up xthe body of Christ, 13until we all attain to xthe unity of the faith and of the knowledge of the Son of God, xto mature manhood, to the measure of the stature of xthe fullness of Christ, 14so that we may no longer be children, xtossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in xdeceitful schemes. 15Rather, xspeaking the truth in love, we are to xgrow up in every way into him who is xthe head, into Christ, 16xfrom whom the whole body, joined and held together by every joint with which it is equipped, xwhen each part is working properly, makes the body grow so that it builds itself up in love.
The Context is clearly talking about being meek, being humble, gentle, patient, loving, etc. in bearing with one another. And then goes on to talk about how that unity plays out among the different gifting/calling within the Body of Christ. I missed the part about God not keeping His Word throughout the prophets concerning what He will do in the end (repeatedly in the context of "The Day of the Lord", "The Day of the Lord's vengeance", etc. - the second coming unless you are a hyper Preterist who thinks He already did that in 70AD? That would, I believe, be one of those "strange winds of doctrine" Paul refers to here) among the Jews, or where is the nullifying of Romans 11? Or a good/real explanation for why Jesus didn't correct the apostles in Acts 1 just before His resurrection, nor did Luke give ANY indicators that they didn't understand (when every other example in scripture where the disciples just "didn't get it" had either Jesus correcting their ignorance or God had the writer make an indicator statement in the immediate context letting us know they were "off").
Then you said:
"Paul was also a Jew but he never called himself a "Messianic Jew" that expression is not found in the Bible !"
Sure, the words "Messianic Jew" are not in scripture. Neither is the word "trinity" by the way. Nor "Continuist". Nor "Cessationist". Nor a lot of other words we know the meanings to. The Biblical language would be "believing Jew" ("Messainic Jews" who "believe" Jesus was the "Messiah") & "unbelieving Jew". This is pretty straight - forward. The Bible never uses the Word "Hermeneutics" either (or a lot of other words), but I trust you know what it means? It's important because scripture says, "not many of you should presume to be teachers" & "study to show thyself approved, a workman who need not be ashamed, but rightly dividing the Word of Truth"! And the Bible is God's "Logos" (written word) to us empowered by His "Pnuemas" (Spirit), which gives us HIS "Rhema" (revelation) of Truth. The Bible is not a comprehensive unabridged dictionary to the only usable words in the English (and/or Hebrew/Greek) language.
And,
"Therefore from now on we recognize no one according to the flesh; even though we have known Christ according to the flesh, yet now we know Him in this way no longer. 17Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come. 2 Corinthians 5:17
So do I not recognize you as a man or a woman as a woman? That's "according to the flesh" right? So all men and all women should not be "recognized according to the flesh"?
Again, let's look at the total context of 2 Corinthians 5 & what the scripture IS & IS NOT referring to:
"11Therefore, knowing xthe fear of the Lord, we persuade others. But xwhat we are is known to God, and I hope it is known also to your conscience. 12xWe are not commending ourselves to you again but xgiving you cause to boast about us, so that you may be able to answer those who boast about outward appearance and not about what is in the heart. 13For if we xare beside ourselves, it is for God; if we are in our right mind, it is for you. 14For the love of Christ xcontrols us, because we have concluded this: that xone has died for all, therefore all have died; 15and he died for all, xthat those who live might no longer live for themselves but xfor him who for their sake died and was raised.
16From now on, therefore, xwe regard no one according to the flesh. Even though we once regarded Christ according to the flesh, we regard him thus no longer.17Therefore, if anyone is xin Christ, he is xa new creation. xThe old has passed away; behold, the new has come. 18All this is from God, xwho through Christ reconciled us to himself and gave us xthe ministry of reconciliation; 19that is, in Christ God was reconciling the world to himself, xnot counting their trespasses against them, and entrusting to us xthe message of reconciliation."
So what is actually being referenced here is the same thing as what the book of Galatians & elsewhere is referring to: "THOSE WHO BOAST ABOUT OUTWARD APPEARANCE & NOT WHAT IS IN THE HEART" So what is Paul speaking of exactly? Clearly, the Law. Circumcision. UnMixed fabric on garments. ETC.
So, yes, I would not say to bow down to "Orthodox Jews" (another word not in scripture, but I trust you know what that means) because they have outward appearances keeping the Law! Quite the contrary. That has NOTHING to do with the subject, or OP, or Romans 11, Acts 1, most of the Biblical prophetic declarations of the OT prophets concerning what would happen around "The Day of The Lord", etc.
And as far as Ephesians 3, yes & Amen that Paul was sent to share the Gospel with the Gentiles (I fit in that category & I assume you do too?), so praise God. But Paul is merely stating that God called, appointed & sent Him primarily to the Gentile's, as scripture shows elsewhere Peter was sent primarily to proclaim the Gospel to the Jews. So what? What does that have to do with the OP?
Let's look at Romans 11 (I know you don't have time, but I happen to think Romans 11 since its in the same Word of God is also important as is Ephesians 3):
The Remnant of Israel
1I ask, then, xhas God rejected his people? By no means! For xI myself am an Israelite, a descendant of Abraham, a member of the tribe of Benjamin (*why is Paul saying that? Hasn't he read 2 Cor 5, Ephesians 3, etc? Oh yeah, he wrote them - my added, obviously). 2xGod has not rejected his people whom he xforeknew. Do you not know what the Scripture says of Elijah, how he appeals to God against Israel? 3x"Lord, they have killed your prophets, they have demolished your altars, and I alone am left, and they seek my life.” 4But what is God's reply to him? x"I have kept for myself seven thousand men who have not bowed the knee to Baal.” 5So too at the present time there is xa remnant, chosen by grace. 6xBut if it is by grace, it is no longer on the basis of works; otherwise grace would no longer be grace.
7What then? xIsrael failed to obtain what it was seeking. The elect obtained it, but the rest xwere hardened, 8as it is written,
x"God gave them a spirit of stupor,
xeyes that would not see
and ears that would not hear,
down to this very day.”
9And David says,
x"Let their table become a snare and a trap,
a stumbling block and a retribution for them;
10
let their eyes be darkened so that they cannot see,
and bend their backs forever.”
Gentiles Grafted In
11So I ask, did they stumble in order that they might fall? By no means! Rather through their trespass xsalvation has come to the Gentiles, so as to make Israel jealous. 12Now if their trespass means riches for the world, and if their failure means riches for the Gentiles, how much more will their full inclusion (*what? "will" in future tense? Full inclusion? Paul must not have read much Replacement theologians' works, huh? - my added) mean!
13Now I am speaking to you Gentiles. Inasmuch then as xI am an apostle to the Gentiles, I magnify my ministry 14in order somehow to make my fellow Jews jealous, and xthus save some of them.15For if their rejection means xthe reconciliation of the world, what will (*"will" in future tense - my added) their acceptance mean but life from the dead?16xIf the dough offered as firstfruits is holy, so is the whole lump, and if the root is holy, so are the branches.
17But if xsome of the branches were broken off, and you, xalthough a wild olive shoot, were grafted in among the others and now share in the nourishing root of the olive tree, 18do not be arrogant toward the branches. If you are, remember it is not you who support the root, but the root that supports you. 19Then you will say, "Branches were broken off so that I might be grafted in.” 20That is true. They were broken off because of their unbelief, but you xstand fast through faith. So xdo not become proud, but xstand in awe. 21For if God did not spare the natural branches, neither will he spare you. 22Note then the kindness and the severity of God: severity toward those who have fallen, but God's kindness to you, xprovided you continue in his kindness. Otherwise xyou too will be cut off. 23And xeven they, if they do not continue in their unbelief, will be grafted in, for God has the power to graft them in again. 24For if you were cut from what is by nature a wild olive tree, and grafted, contrary to nature, into a cultivated olive tree, how much more (*but Paul, isn't that language showing favoritism? - my added) will these, the natural branches, be grafted back into their own olive tree.
The Mystery of Israel's Salvation
25xLest you be wise in your own conceits, I want you to understand this mystery, brothers: xa partial hardening has come upon Israel, xuntil the fullness of the Gentiles has come in. 26And in this way all Israel will be saved, as it is written,
x"The Deliverer will come xfrom Zion,
he will banish ungodliness from Jacob”;
27
"and this will be my xcovenant with them
xwhen I take away their sins.”
28As regards the gospel, they are enemies of God for your sake. But as regards election, they are xbeloved for the sake of their forefathers. 29For the gifts and xthe calling of God are irrevocable. 30Just as xyou were at one time disobedient to God but now have received mercy because of their disobedience, 31so they too have now been disobedient in order that by the mercy shown to you they also may now receive mercy. 32For God xhas consigned all to disobedience, that he may have mercy on all. (*sounds an awful lot like election & Soveriegn grace explained back on Romans 7 to me! - my added)
33Oh, the depth of the riches and xwisdom and knowledge of God! xHow unsearchable are his judgments and how inscrutable his ways!
34
"For xwho has known the mind of the Lord,
or xwho has been his counselor?”
35
"Or xwho has given a gift to him
that he might be repaid?”
36For xfrom him and through him and to him are all things. xTo him be glory forever. Amen.
Interesting because I even had a dream about this very discussion/explanation last night. The scriptures are true. ALL OF THEM. In their proper context taken as part of the whole, full counsel of the sum of all of God's Words. I could pull out a verse here & 1 there & build a thousand unbiblical, incomplete doctrines. The fact is, no one is saved outside of the Gospel. But/And, God is Himself going to Sovereignly fulfill ALL of His promises in the end (before the Day of the Lord) & do a mighty work of revival in Israel (just like how if you are saved it was through God's sovereign grace, not your brilliant wisdom or something good in you in turning to Christ).
I am about done with this whole conversation/subject. If people are choosing to not want to look squarely & honestly at ALL the scriptures, in context, & have been reading every replacement theology website there is, & have chosen to buy into it full-bore with no openness to looking at ALL of the things God says in His Word in their full context, then what good is the discussion as a whole? A predetermined suppositional argument stance will not allow anyone (myself included) to grow in knowledge, wisdom, or understanding. Like any other Biblical subject of study, When you really look at ALL of the scriptures on the subject with an open heart/mind, it just becomes clearer, & clearer, & clearer IMHO.
God Bless you all,
Jeff
