The following is from a book by Professor WA Liebenberg titled There is only "one" covenant, and Christians have grossly missed it.
There is a Gospel, the "true Gospel" that is unbreakable and unchangeable: this is YHWH's Gospel, and it is cast in concrete. And then there is the gospel that the majority of Christianity believes in. This is what I'd like to call, "The Impossible Gospel". The following three reasons will explain why:
1) Reason NO. 1: You cannot add or take away from the Torah:
The first point implies that Y'shua and all the apostles would've been bound by this law. They could not add to nor take away from the Torah.
2) Reason NO. 2: You must test it to see if it is the truth, and cannot lead you astray or into rebellion:
Point number two explains to us clearly that if a person, Pastor, Prophet, or Teacher leads the nation astray (away from YHWH's ways), the prophet has to be stoned and is classifed as a false Prophet or Teacher.
So what is "The Way" - meaning the only "correct way"? Again Scripture (YHWH's own words) gives us the defining answer, not man's opinion:
YHWH's Torah is not the way of death, but the way of LIFE! Torah is designed to improve, bless, protect and to enhance life significantly - wow! Ultimately, Torah is YHWH's instructions in righteousness. (2 Tim 3:16)
That means you must test every single thing against the Torah: the Torah is the only measuring stick that can and should be used for correct doctrine. Any teaching, saying, preaching, even an interpretation of scripture contradicting the Torah, is false. This obviously makes the one teaching it a false prophet (proved above) and liar (proven later, and that is YHWH's standard.
3) Reason No. 3: YHWH and Y'shua cannot change. (Malachi 3:6 and Heb 13:8)
Let's ask the question, "Is YHWH random and changes things without informing His followers, us?" also "Can Elohim do anything without letter the Prophets know: i.e., that His Son will do away with the Law?"
No, He cannot. YHWH clearly tells us He will do nothing unless He reveals and declares it to His Prophets. If YHWH wanted His Son to die so that we can now eat pork, surely He would have made it known and distinctly told us as much. No, there is not one single verse that says the Torah would be done away with - not one single prophesy. The problem is man's grossly incorrect interpretation of the Word that steers Christians away from the Torah! And these incorrect interpretations stem from a lack of knowledge of Torah.
Pointnumber 3 proves to us that something was planned, and not part of a misinterpretation. If YHWH prophesies that something will happen, then we know that it must happen. However, if it is not prophesied, then we must also know that it will not happen.
As a Christian, please answer these questions: "Is Y'shua without Sin?" Is it at all possible that Y'shua could sin? The answer is obvious that Y'shua is sinless and cannot sin at all, not even in the smallest matter. Now follow this argument to see where Christianity is flawed concerning the Torah:
So here we clearly see, they could not find anything Y'shua did, wrong. Y'shua was terefore without sin; so much so that they had to call in false witnesses to condemn Him. Remember, their country's laws were Torah. They judged Y'shua based on the Torah, as they have always done. Surely if He taught rebellion against the Torah of YHWH, they wouldn't need to call in false witnesses!
For a moment, let's get back to the question, "What is sin?" We saw clearly from Scripture that "sin is the transgression of the law". Meaning, we can all agree that Y'shua did not transgress the Law.
By reasoning and intellectual comprehension, it is clear that Y'shua then never broke any one of the Commandments of the Law. That means He guarded every single Commandment of the Law! Let us give you an example:
Y'shua was before Caiaphas and He did not want to speak. (Matt 26:61-64). Caiaphas commanded Him: "I adjure you to speak!" All of a sudden Y'shua began to speak, why?
Matthew tells us how Caiaphas put Y'shua on solemn oath, and used the oath of testimony saying:
Such an adjuration was understood to render an answer legally necessary, despite the fact that it was illegal to do this trial for life. By Law Y'shua had to reply:
In this case, silence would have been by itself an admission of guilt. Another fact is if Y'shua did not speak here, He would have broken a Law which then in turn would have made Him a sinner.
Summary of "The Impossible Gospel"
The foundation of the impossible Gospel is as follows:
1) Was the Torah changed?
a) You cannot CHANGE the Law (Torah)
b) If somebody changes it, that person must be stoned.
c) It must be revealed first by a Prophet, such as in the Old Covenant before YHWH can change it, and Y'shua the Prophet did not change it.
2) Can Y'shua teach that the Torah is no longer applicable? YHWH says the Torah is FOREVER, and forever means FOREVER.
a) If He did, He would've been stoned.
b) It would not have been "false witnesses" that condemned Y'shua, but true witnesses.
3) It was NEVER revealed that the Torah would come to an end: in fact, we see the complete opposite.
a) Jeremiah chapter 31 talks about a New (renewed) Covenant that will be made, but the New Covenant includes the Law: Jer 31:33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
b) Ezekiel 38 and 39 deals with the Battle of Gog and Magog as well as with the Battle of Armageddon at the end of the Tribulation Period. Chapters 40-48 deal distinctly with the "Olam Haba" (the Millennial Reign of Y'shua) - the Thousand Years of Peace. Ezekiel in chapters 40-48 gives great detail how Y'shua will then reign in His Kingdom on earth. In these chapters, we see Temple sacrifices being restored (for celebrations and food for the Priests), Levites and Cohanim (Priests) resuming their responsibilitites in the Rebuilt Temple, everything only according to the Torah. If the Law was been done away with, why would YHWH restore it again? No, the Law has never been done away with. Christians have been blinded by Satan from YHWH's very truths.
CONCLUSION
The basis of the "Impossible Gospel" is: "if Y'shua taught against the Torah, then He would have been disqualified as the Messiah and would've been a false messiah". The majority of Christianity believes in a messiah that cannot possibly exist. It's a messiah that broke the law, by changing it, while it was not prophesied to happen. It is a messiah that was a sinner, since he broke the Torah.
So, we either accept both the Torah AND the Messiah, or reject both the Torah AND the Messiah.
Y'shua could not teach against Torah; the same goes for ANY other Scripture author, period.
