Thanks for that gracious spirit of reply Keith. I have already pointed out that this subject requires much time. It is the great recurring thread in Scripture, that scholars like Darby never noticed it almost beggars all belief and their hapless failure to notice has led so many dedicated Christians to go down the wrong garden path, and it has become huge mote in their eye....that stops them seeing the most glorious mystery of the Bible.
You said Keith that "you do not find the Church in the Old Testament" you would need to clarify that. For "church" means "ecclesia" and again my namesake Stephen spoke of: "This is he who was in the church[eclessia] in the wilderness.....who received the lively oracles to give unto us." Acts7:38 Of course the mystery revealed to Paul about the Gentiles was not known back then.
I have no idea Keith how you could say the Gospel of the Circumcision and the Gospel of the uncircumcision are the same. It is clear their are two churches in Scripture, like their are two Adams, Cain and Abel, Jacob and Esau, Isaac and Ishmael David and Saul. Just on this subject I will mention a few of the many used in Scripture.
WE have two creations one out of water in Gen.1 and one out of the earth or dust of Gen.2. We have the old creation and the new creation. We have two gardens one in Genesis and one in the Book of Revelations.
WE have two trees in the Garden of Eden. We have two Kingdoms of God the Kingdom of God in heaven and the kingdom of God on earth.
It is clear that Christ was a minister sent only to the lost house of Israel, who rejected Him. Through grace the Gospel is re-offered 20 times in the Book of acts to the Jews and their gentile proselytes. It is not until Acts 13:2 that Paul and Barnabas are separated by the Holy spirit for a new ministry to the Gentiles who are not even proselytes or circumcised.
This is the most radical change in the Bible that introduces a new dispensation and new covenant along with a new Kingdom that of heaven, for the Jews were alway promised the Kingdom of God on earth. So you have two Gospels one by Paul to the Uncircumcision but this in no discounts Jews from taking up this Gospel. But it certainly was a Gospel that Peter James and John and the rest of the circumcision or Jewish Christians rejected.
Now this confrontation is the great schism of the New Testament like that in Ireland between the Protestants and the Catholics. I have not really even touched on this subject it requires so many posts to even give it justice.
Yes Keith notwithstanding I do agree with your comment: "For we are all members of one body and in fellowship with all who called on the name of the Lord everywhere." Yes there is a New Humanity in Christ where both the Jewish believers and the Gentile believers the circumcision and the uncircumcision have their "middle wall of partition [that separates them into two classes of believers] broken down."
The Unity of the Body is fundamental.
But if anyone has any questions let us clear them up, for we clearly have two groups..............
1. The Jews the circumcision who had the earthly promises and election unto them were entrusted the Oracles of God" as having jurisdiction over the Kingdom of God on earth, see also John's Book of Revelations 21:24. Please note how the Apostles to the circumcision Peter James and John start their Epistles and who they address those Epistles to....it is very illuminating! Also note how the Law is still retained with the circumcision.
How they are also saved through blood sacrifice of Christ through repentance and sacrifice.
2. Then you have the Gentiles, who have never lived under Law, "alienated from the citizenship of israel....having no expectation, and without God in the world" Eph.2:12 but through Grace being given the Kingdom of Heaven and a ministry "to make God's manifold wisdom known amongst the celestials." But this second group in no way discounts the Jews who accept Paul's Gospel.
Paul's Gospel does not require good works, or even sacrifice though in addressing the Jews he will mention that, but His Gospel is based on Justification that no sin is imputed for the Gentiles positionally IN CHRIST are spotless and perfect....even more "seated in the heavenly places in Christ" And as I said Paul's Gospel embraces Jew and Gentile who would believe Paul's Gospel unlike that of the Gospel of the Circumcision of Peter, James and John.
This truth is pivotal to Scripture and explains what the Rapture really is........it is no "beam me up Scottie" stuff...no, absolutely no but rather something far more mysterious and glorious.
So a Christian Mystic has a charter and this is the charter. I am not ashamed I know I am in good company.......
We speak the hidden mystical Wisdom of God, which God ordained before the World unto our Glory: Which none of the Princes of this World knew: For had they known it, they would not have crucified the Lord of Glory. But, as it is written, Eye hath not seen, nor Ear heard, neither hath it entered into the Heart of Man to conceive the Things which God hath prepared for them that love him. But God hath revealed them unto us by his Spirit: For the Spirit searcheth all Things, yea, the deep Things of God. For what Man knoweth the Things of a Man, save the Spirit of a Man which is in him? Even so the Things of God knoweth no Man, but the Spirit of God. Now we have received, not the Spirit of this World, but the Spirit which is of God; that we might know the Things that are freely given us of God. Which Things also we speak, not in the Words which Man's Wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual Things with spiritual. But the natural Man receiveth not the Things of the Spirit of God: For they are Foolishness unto him; neither can he know them, because they are spiritually discerned. But he that is spiritual judgeth, or discerneth all Things.
