I haven't heard of Dispensationalism for a long time, speaking in tongues and the rapture were their marks. I attended a Dispensationalism church when I was innocent and naive, and I only learned about Dispensationalism when I moved onto an other church.
Dispensationalism is a religious system of dividing scripture into dispensations, or sections, with unique narratives misusing scripture; while using English, they redefine jargon in an Orwellian manner such that you think you disagree but in truth you have not understood what they have said. Intrinsic to their narratives is Ribera's futurism, a hypothetical presented by the Jesuit Ribera at the Council of Trent. I say hypothetical because the Catholic Church doesn't seem to have adopted it, it only was intended to show there was other ways of interpreting scripture than the protestant accusation of the Papacy being the Beast of Revelation. One of the many flaws in Futurism is it has Satan confirming a covenant in place of Christ. Dispensationalism is complex and I have only sundry knowledge. From a small booklet, (The Gospel and the Kingdom) by Ivan Panin, who was Pentecostal minister, refuting Dispensationalism, I learned that Dispensationalism had 68 Gospels; Panin's conclusion was, Dispensationalism requires a new Gospel, a new Kingdom and a new Bible. Dispensationalism, as a virus, invaded the Pentecostal churches in the 1930's I believe, fragments of it then spread across Christendom.
Is dispensationalism in the room with you right now?
“the Torah testifies of the Abrahamic covenant, the Abrahamic covenant was ratified 430 years before the Law of Moses was given and so it stands apart from and outside of the Torah.”
This is a Dispensationalism type of statement in my opinion. It means nothing to me. I do not know what the Abrahamic covenant is; “Law of Moses”, is a metaphor that I assume refers to the Law of God, under the administration of Moses. What does ratify mean; Abraham's descendants are probably around 60% of the worlds population; but as a single nation I would suggest the kingdom of God or the New Jerusalem.
I try to use Biblical terms as much as I can to describe Biblical concepts. The Law is often called "The Law of Moses" in both the Old Testament and the New Testament because it was given by God to Moses who wrote the first 5 books of the Bible (the Torah). Jesus Himself called it this.
[Luk 24:44 NASB95] 44 Now He said to them, "These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and the Psalms must be fulfilled."
[Act 28:23 NASB95] 23 When they had set a day for Paul, they came to him at his lodging in large numbers; and he was explaining to them by solemnly testifying about the kingdom of God and trying to persuade them concerning Jesus, from both the Law of Moses and from the Prophets, from morning until evening.
[Deu 31:24 NASB95] 24 It came about, when Moses finished writing the words of this law in a book until they were complete,
[2Ch 34:14 NASB95] 14 When they were bringing out the money which had been brought into the house of the LORD, Hilkiah the priest found the book of the law of the LORD [given] by Moses.
[Jos 23:6 NASB95] 6 "Be very firm, then, to keep and do all that is written in the book of the law of Moses, so that you may not turn aside from it to the right hand or to the left,
Since Jesus (God) Himself called it The Law of Moses, and many in the Old and New Testament call it The Law of Moses, I feel like we can safely call it The Law of Moses without ruffling too many theological feathers.
Now when I say the Torah testifies of the Abrahamic covenant, I mean that the Abrahamic covenant pre-dates The Law of Moses, and therefore, stands apart from it. Yes, it is written "about" in the law, but since it came about before the law and is a separate covenant from the covenant of The Law, we can say that it is testified about or witnessed by The Law, but not a part of it.
[Rom 3:21-22 NASB95] 21 But now apart from the Law [the] righteousness of God has been manifested, being witnessed by the Law and the Prophets, 22 even [the] righteousness of God through faith in Jesus Christ for all those who believe; for there is no distinction;
Paul views the righteousness which comes by faith as something "apart from" the law... although he says it is "witnessed by" the law. So the law testifies (bares witness) to the righteous which comes through faith, but it is apart from the law of Moses.
[Gal 3:6-8 NASB95] 6 Even so Abraham BELIEVED GOD, AND IT WAS RECKONED TO HIM AS RIGHTEOUSNESS. 7 Therefore, be sure that it is those who are of faith who are sons of Abraham. 8 The Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, [saying,] "ALL THE NATIONS WILL BE BLESSED IN YOU."
[Gal 3:14-18 NASB95] 14 in order that in Christ Jesus the blessing of Abraham might come to the Gentiles, so that we would receive the promise of the Spirit through faith. 15 Brethren, I speak in terms of human relations: even though it is [only] a man's covenant, yet when it has been ratified, no one sets it aside or adds conditions to it. 16 Now the promises were spoken to Abraham and to his seed. He does not say, "And to seeds," as [referring] to many, but [rather] to one, "And to your seed," that is, Christ. 17 What I am saying is this: the Law, which came four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise. 18 For if the inheritance is based on law, it is no longer based on a promise; but God has granted it to Abraham by means of a promise.
[Gen 15:5-6 NASB20] 5 And He took him outside and said, "Now look toward the heavens and count the stars, if you are able to count them." And He said to him, "So shall your seed be." 6 Then he believed in the LORD; and He reckoned it to him as righteousness.
[Gen 17:7 NASB20] 7 "I will establish My covenant between Me and you and your seed after you throughout their generations as an everlasting covenant, to be God to you and to your seed after you.
So the covenant of righteousness through faith in the gospel of Jesus Christ was given to Abraham. This was 430 years before The Law was given to Moses as Paul says in Gal 3:17. Once a covenant is ratified, it can no longer have conditions added to it, so 430 years later when covenant of The Law is given to Moses, it does not modify the previous covenant of faith. The covenant of faith given to Abraham stands apart from the law.
[Jer 31:31-33 NASB95] 31 "Behold, days are coming," declares the LORD, "when I will make a new covenant with the house of Israel and with the house of Judah, 32 not like the covenant which I made with their fathers in the day I took them by the hand to bring them out of the land of Egypt, My covenant which they broke, although I was a husband to them," declares the LORD. 33 "But this is the covenant which I will make with the house of Israel after those days," declares the LORD, "I will put My law within them and on their heart I will write it; and I will be their God, and they shall be My people.
Who lead them out of Egypt? Moses. What covenant is Jeremiah talking about that Israel broke? The Law of Moses.
If the promise of a great nation is a covenant, then the need of circumcision is a covenant also; what use is being a descendant of Abraham if one does not belong to God?
The Promise of the Land to Israel was a type of the kingdom of God, and called that.
The promise of the Messiah to Abraham was also a covenant.
I have heard from reliable scholars that Sarah was Abraham's half sister, his deception was he withheld that she was his wife and this was profitable for him, and this is a type, of which Jacob's stealing the promise and the inheritance from his brother, is an anti-type.
This promise passed from Abraham, through Issac, Jacob, Joseph, through his two sons and their descendants. This promise was only ratified since Christ, mainly the last 700 years, and coincides with Gentiles treading the Sanctuary under foot and the beasts of Revelation.
The scriptures have to be a homogeneous set in the context of the established word, the Law and the Prophets, cannot be changed.
Circumcision is part of God's covenant with Abraham (the covenant of righteousness by faith). It also includes the promise of the land of Israel.
However, circumcision may now be "of the heart" now that the Holy Spirit is come. It is arguable that this was the intended meaning all along.
You can see from the Jeremiah 31:31 passage above that the new covenant is "of the heart." Ezekiel prophesies:
[Eze 36:26 NASB95] 26 "Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh.
Even Moses prophesied:
[Deu 30:6 NASB95] 6 "Moreover the LORD your God will circumcise your heart and the heart of your descendants, to love the LORD your God with all your heart and with all your soul, so that you may live.
Paul said:
[Rom 2:28-29 NASB95] 28 For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh. 29 But he is a Jew who is one inwardly; and circumcision is that which is of the heart, by the Spirit, not by the letter; and his praise is not from men, but from God.
Circumcision was first implemented in Genesis 17 when God changed Abram's name to Abraham signifying he would be the Father of Many Nations and made His covenant with him.
[Gen 17:7-10 NASB95] 7 "I will establish My covenant between Me and you and your seed after you throughout their generations for an everlasting covenant, to be God to you and to your seed after you. 8 "I will give to you and to your seed after you, the land of your sojournings, all the land of Canaan, for an everlasting possession; and I will be their God." 9 God said further to Abraham, "Now as for you, you shall keep My covenant, you and your seed after you throughout their generations. 10 "This is My covenant, which you shall keep, between Me and you and your seed after you: every male among you shall be circumcised.
But Paul explains to us what was happening here:
[Rom 4:9-17 NASB95] 9 Is this blessing then on the circumcised, or on the uncircumcised also? For we say, "FAITH WAS CREDITED TO ABRAHAM AS RIGHTEOUSNESS." 10 How then was it credited? While he was circumcised, or uncircumcised? Not while circumcised, but while uncircumcised; 11 and he received the sign of circumcision, a seal of the righteousness of the faith which he had while uncircumcised, so that he might be the father of all who believe without being circumcised, that righteousness might be credited to them, 12 and the father of circumcision to those who not only are of the circumcision, but who also follow in the steps of the faith of our father Abraham which he had while uncircumcised. 13 For the promise to Abraham or to his descendants (seed) that he would be heir of the world was not through the Law, but through the righteousness of faith. 14 For if those who are of the Law are heirs, faith is made void and the promise is nullified; 15 for the Law brings about wrath, but where there is no law, there also is no violation. 16 For this reason [it is] by faith, in order that [it may be] in accordance with grace, so that the promise will be guaranteed to all the descendants, not only to those who are of the Law, but also to those who are of the faith of Abraham, who is the father of us all, 17 (as it is written, "A FATHER OF MANY NATIONS HAVE I MADE YOU") in the presence of Him whom he believed, [even] God, who gives life to the dead and calls into being that which does not exist.
[Eph 1:13-14 NASB20] 13 In Him, you also, after listening to the message of truth, the gospel of your salvation--having also believed, you were sealed in Him with the Holy Spirit of the promise, 14 who is a first installment of our inheritance, in regard to the redemption of [God's own] possession, to the praise of His glory.
Since the Holy Spirit wasn't given until after Jesus ascended, Abraham needed to be circumcised in his flesh as a placeholder for circumcision of the heart (or the indwelling of the Holy Spirit). Circumcision is the seal of the righteousness which comes by faith.
