Good article! Especially the Greek! Of course, it makes no sense from any point of view, that if Paul says we are all one in Christ, as per Gal. 3:28, that a few pages later on his scroll, he would say that Israel is different than the church. The context is very clear, if we look at Galatians as one scroll or book, instead of separate chapters and books. God did not put the divisions in the Bible, although of course, they are convenient!
"There is neither Jew nor Gentile, neither slave nor free,nor is there male and female, for you are all one in Christ Jesus." Gal 3:28
It is also important to remember why Paul wrote this letter to the Galatians. It was because they were going back to Judiasm. They put themselves under the law, and thus he would never tell them that Israel is different than the church, or these Judiasers would have latched onto that letter as not a rebuke, but rather permission to go back to being Jews, and forgetting Christ died for them, and for everyone.
"I am astonished that you are so quickly deserting the one who called you to live in the grace of Christ and are turning to a different gospel— 7 which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. 8 But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let them be under God’s curse! 9 As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let them be under God’s curse!" Gal 1:6-9
And then, a few verses down:
"For you have heard of my previous way of life in Judaism, how intensely I persecuted the church of Godand tried to destroy it. 14 I was advancing in Judaism beyond many of my own age among my people and was extremely zealous for the traditions of my fathers. 15 But when God, who set me apart from my mother’s womb and called me by his grace, was pleased 16 to reveal his Son in me so that I might preach him among the Gentiles, my immediate response was not to consult any human being." Gal. 1:13-16
Why was Paul talking about being a Jew and persecuting Christians? Because he wanted to remind them that he had been a "Jew of Jews" and God called him away from those traditions to Jesus Christ. People!!! This is the context of Galatians! Paul telling them that if they are in Christ, they do not need to be Jews anymore. There is no promise to save a separate Israel. Israel disobeyed God for almost 500 years. They were deported to captivity. But when God brought them back they had beome legalist! And God knew this, so as part of his eternal plan he sent Christ to take away our sins. Everyone - to the Jew first and then the Gentile.
"For I am not ashamed of the gospel, because it is the power of God that brings salvation to everyone who believes: first to the Jew, then to the Gentile." Romans 1:16
This whole argument is so silly. Either Christ died for us all, or his sacrifice needs something extra, like a blood line to Abraham. Christ came to save us from the sacrificial system to cleanse our sins, because it did not work. He was the once for all sacrifice.
"When he said above, “You have neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings” (these are offered according to the law),9 then he added, “Behold, I have come to do your will.” He does away with the first in order to establish the second.10 And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.11 And every priest stands daily at his service, offering repeatedly the same sacrifices, which can never take away sins. 12 But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God,13 waiting from that time until his enemies should be made a footstool for his feet. 14 For by a single offering he has perfected for all time those who are being sanctified." Hebrews 10:8-14
