If Hebrew isn't important, then how come the writers of the New Testament, including the Revelation of Jesus given to John, felt that it was so important so to include it in their writings?
Act_21:40 And when he had given him permission, Paul, standing on the steps, motioned with his hand to the people. And when there was a great hush, he addressed them in the Hebrew language, saying:
Act_22:2 And when they heard that he was addressing them in the Hebrew language, they became even more quiet. And he said:
Act_26:14 And when we had all fallen to the ground, I heard a voice saying to me in the Hebrew language, ‘Saul, Saul, why are you persecuting me? It is hard for you to kick against the goads.’
Php_3:5 circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the law, a Pharisee;
Rev_9:11 They have as king over them the angel of the bottomless pit. His name in Hebrew is Abaddon, and in Greek he is called Apollyon.
Rev_16:16 And they assembled them at the place that in Hebrew is called Armageddon.
And as far as the Hebrew no longer being valid, the early church fathers have much to say about the assemblies of Christ that continued in the Hebrew language, even unto the 4th century...

...and while I do not agree that the Nazarenes were “Jewish” as ‘Jewish” is defined by the Talmud and not the bible, I have studied and verified the writings in this book, historical writings of the earliest church fathers that clearly reveal that indeed, the Hebrew language was never cast aside for the Greek and why? Because the Greeks were going to the Hebrew speaking synagogues to hear the Gospel of Christ!
Act 13:42 As they went out, the people begged that these things might be told them the next Sabbath. 43 And after the meeting of the synagogue broke up, many Jews and devout converts to Judaism followed Paul and Barnabas, who, as they spoke with them, urged them to continue in the grace of God. 44 The next Sabbath almost the whole city gathered to hear the word of the Lord. 45 But when the Jews saw the crowds, they were filled with jealousy and began to contradict what was spoken by Paul, reviling him.

So the questions are “Why did the majority of the church fathers divorce themselves from the original sect of the Nazarenes that Paul was accused of being the leader of?” “Why were these Nazarenes hated by both Jew & Greco-Roman religions?”
Therefore, why nit pick over tongues rather than reply with substance? Ad hominem attacks are used by those who can not support their theological beliefs using His Word alone.
And yes, the chief cornerstone is Christ and it was the faith of Peter, i.e. the faith of Christ in him that Christ's assembly is built upon.
Acts 7:38 Christ's assembly was gathered in the wilderness at Mt Sinai...
1Peter 1-2 Peter instructs us on that assembly in the wilderness and the difference between those who believed and those who did not
1Cor 10 Paul instructs us that Christ was with the Israelites in the wilderness and that they are examples that we are to learn from (see also Heb 3-4)
And finally, why where the "KEYS" of binding and unbinding given to ALL the disciples of Christ? Jesus said He gave them to ALL, not just to Peter. Matthew 18:18 Shalom!
The Judaizers in Acts 15 and Galatians, who believed Christians had to be circumcised, and were commanded to keep the law of Moses, have their form of Judaizing, you have yours.
In fact, it has been my experience, that most who want to impose your form of Judaizing on Gentiles, that I have met, also do so with the law of Moses.
With the exception of circumcision, that is. Most won’t go that far. Are you one of those who believe that Gentiles have to be circumcised?
