Is the Great Commission irrelevant for the church now?

The Commission expanded precisely according to what Christ prescribed....Jews, Samaritans, Gentiles, and post-Apostles the rest of the planet.

So why do you think Peter told Cornelius this in Acts 10, before he explained he had a special vision from God just before that?

28 And he said unto them, Ye know how that it is an unlawful thing for a man that is a Jew to keep company, or come unto one of another nation;

Do you think Peter understood the GC as to uttermost part of the earth?

The command to go to preach the Gospel is to every creature(Mark 16). to every nation (Mat. 28) or anywhere where Christ was not named (Romans 15:20) , even to the regions beyond (2 Cor. 10:16) or to the uttermost part of the earth (Acts 1:8). This gospel is always to the Jew first and then to the Gentiles (Romans 1:16). This going out of the early beleivers is to witness for Christ and to baptized every believers, then be taught with the sound doctrine. For Paul this teaching ministry was seen in his entire missionary journey.

You are not answering my question.

Why do you think Peter was so reluctant to go to Cornelius house in Acts 10, if he truly understood that the GC was meant for the Gentiles at the same time as to the Jews?

My answer is that Peter understood the OT prophecy, that the Jews as a nation must accept Christ as their Messiah first, before the Gentiles could be reached.

Nonsense. Peter was hesitant for now obsolete (and likely improper and unscriptural) beliefs about Gentiles. God dispelled Peter's trepidations in no uncertain terms. Doubtless Jesus made things quite clear, but Peter was a tough nut to crack. Peter had trouble with Gentiles much later in a very similar way, triggering the excoriating rebuke by Paul.

One of the commandments taught by Jesus is "Go not into the Gentiles". Put yourself in Peter's shoes, do you think he understood Jesus's instructions wrongly?

Are all aware Jesus said, Himself, I have two flocks? He mentioned He would teach His own people first and later He would send His disciples to the Gntiles. Peter understood after his vision. As for Pau admonishing Peter, if this is so, it was a differetn Peter for Paul's name i not found onthe foundations of our City of Gold. That gold being the faith of the believers.

Understan please that Paul had no gospel other than that of Jesus Christ, and Paul was ot given anything to add to the Good News. All blessing in Jesus, Yeshua.

Jesus saved Paul to specifically send him to the Gentiles. This was mentioned a number of times in Acts.

As for the 12 original apostles, here is what they concluded after the Jerusalem Council event, Galatians 2

9 And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.

The 12, together with James, agreed that they will confine their ministry only to the Jews.

Do you understand Paul has testified of himself throughout the Epistles. Paul made this statement and declasration. Aside from the "men of renown" foretold in Zechariah no other is mentioned in prophfesy other than John the Baptist, the last of the ot PROPHETS Also the Two Witnesses to come and of coure the antichirst are profesied.

Paul has been given an enormous role in the followers of Jesus Christ however many forget that Paul teaches there is NO OTHER Gospel other than that of our Lord, and P=aul also teaches, let anyone be cursed who says he is teaching another gospel for there is no other.

Never affront Pau by inferring there is a gospel of Paul other than the one taught by Jesus Christ to all men. This is a dnagerous view.

What Jesus commanded before His resurrection was clearly different from what He commanded AFTER His resurrection. But Peter had a hard time catching up.

Until His crucifixion, Christ was under the Law, and He limited His ministry primarily to Israel (not exclusively). But when He said "Go therefore and teach ALL NATIONS..." He totally removed that limitation. Indeed He insisted that the Gospel be preached progressively, starting at Jerusalem and then going worldwide "unto the uttermost parts of the earth".

But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. (Acts 1:8)

As we know Peter started in Jerusalem but shortly thereafter He went to Caesarea (with much protestation), and saw Gentiles saved and receiving the gift of the Holy Spirit. We are not given the details about where the other apostles went, but there are various traditions, and we know that Thomas went to India and was martyred after he established churches.

If you read Ephesians 3, Paul was given lots of revelations from the ascended Christ Jesus, that no OT prophet, nor the 12 apostles, ever received. It was all hidden in God.

For this cause I Paul, the prisoner of Jesus Christ for you Gentiles,

2 If ye have heard of the dispensation of the grace of God which is given me to you-ward:

3 How that by revelation he made known unto me the mystery; (as I wrote afore in few words,

4 Whereby, when ye read, ye may understand my knowledge in the mystery of Christ)

5 Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;

6 That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:

7 Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power.

8 Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ;

9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:

Jesus Christ is the mystery. He was hid from the world, the world knew Him not. Yet all was created through Him. Jesus Christ is the mystery revealed to Paul. It was on the road to Damascus that he encountered Christ.

Grace is by Jesus Christ. Jesus Christ is the grace of God. Preaching about the grace of God means to preach about Jesus Christ. Paul was to spread the gospel to gentiles. Jesus spoke in parables about the feast that the King prepared and His own rejected His invitation (the jews) and so all the poor and anyone who would come (gentiles) would be welcome to partake of the banquet. And those who rejected the invitation were to have no part.

Maybe you should read the true Gospel. It applies to all believers. Anyone who has ears to hear. Because the jews rejected this gift of salvation, all parts of the world can now partake in the Kingdom of God. Paul was the least of these yet he was greatly used to spread the truth. Which is Jesus Christ. Any other gospel let be accursed. We are neither jew nor gentile in the Kingdom of God. We are all children of God. We are included as descendants of Abraham who recieve the promise given to Abraham.

So the Gospel is written to all who have ears to hear. Jesus Christ is Lord. That is our master. His Words trump anybody else. Including myself.

So why do you think Peter told Cornelius this in Acts 10, before he explained he had a special vision from God just before that?

28 And he said unto them, Ye know how that it is an unlawful thing for a man that is a Jew to keep company, or come unto one of another nation;

Do you think Peter understood the GC as to uttermost part of the earth?

Here is what the Bible says, and because you left out the remainder of the verse do you suppose I am going to answer what you asked? Get further to get the background....

Acts 10:28 And he said unto them, Ye know how that it is an unlawful thing for a man that is a Jew to keep company, or come unto one of another nation; but God hath shewed me that I should not call any man common or unclean.

Verse 6 made it clear what exactly the mystery is

6 That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:

Jews and Gentiles equal in the eyes of God, that is something that none of the OT prophets, and the 12 apostles were told.
If you think Jesus Christ is the mystery that Paul was referring to, then Isaiah the prophet was made aware of him in Isaiah 53.

Yet, if you search the book of Isaiah for example, no revelation was given to him about the Jews and Gentiles equality. Instead we get passages like in chapter 61

5 Foreigners will be your servants. They will feed your flocks and plow your fields and tend your vineyards. 6 You will be called priests of the Lord, ministers of our God. You will feed on the treasures of the nations and boast in their riches. 7 Instead of shame and dishonor, you will enjoy a double share of honor. You will possess a double portion of prosperity in your land, and everlasting joy will be yours.

In other words, the prophet Isaiah in Chapter 61, verses 5-7, saw Israel in the kingdom ruling and Gentiles serving Israel. The Jews in the Old Testament had never imagined the possibility of equality with Gentiles. The prophet Isaiah never perceived that one body concept that Paul revealed in Ephesians 2-3. Isaiah, like all the Jews then, always saw Jews as citizens of God’s kingdom on Earth, and Gentiles in the same kingdom, but in servitude to the Jews.
