There is much scripture teaches that most Christians have never heard because they do not follow the clues. Meanings are altered because few look for the context of old testament quotes.
You are at church and the speaker reads Ephesians 2:11-14.
“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; That at that time ye were without Christ, being alienated from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. For he is our peace, who hath made both one, and hath broken down the middle wall of partition”.
Did the speaker or your preacher ever examine the words Uncircumcision and Circumcision, alienated, covenants of promise, far off and middle wall of partition to explain the meaning of those verses? This would be very rare. If they taught the actual meaning of that verse, then the lie about Jews and Gentiles most know today would begin to fall apart. This is what I mean when I say most Christians have been misled about meanings in the bible. These clues are not hidden.
Paul used those words to tell us who he was referring the reader of the Word to explain his meaning.
At the time of Christ the Uncircumcision was the House of Israel living off in Europe. The House of Judah was the Circumcision as they had the Law. In the King James bible the word aliens is a verb and is properly translated as alienated. Alienated tells us that at one time the two parties were one. This was never the case between Israel and non-Israelites. When the House of Israel was divorced by God they lost the right to be called Israelites, ruling with God. The scripture is always accurate. From that point forward they were always referred to as Nations or “Gentiles”. Notice the promises of God. God does not break promises. For more examples see Romans 2:14-15 and 9:24-25.
History shows us that the Ten Tribes eventually escaped the Assyrian captivity and moved North through the Caucasus Mountains. The path they took is still called the Pass of Israel today. Over the centuries they moved into Europe and so were “far off” from the House of Judah.
One of the prophecied goals of Christ was to reunite the two Houses of Israel. This is the breaking down of the “middle wall of partition”. Hosea 1:11 shows that the two houses would be reunited.
“Then shall the children of Judah and the children of Israel be gathered together, and appoint themselves one head, and they shall come up out of the land: for great shall be the day of Jezreel.”
Gathered together in the new land promised to King David. The one head is Christ. Ephesians 2 is the fulfillment of prophecy. It does not teach about some Plan B people brought in because Israel supposedly rejected Christ. Mostly only the Edomite leaders of Christ’s day rejected Christ as proven by Christ’s own words in John 5, 8 and 10. The clues lead us to know that those Paul was writing about were those of the Ten Northern Tribes, the House of Israel. Spiritualizing verses to make them all inclusive destroys the original intent.
