Is the Great Commission irrelevant for the church now?

Got ya.

But you cannot deny that Jesus gave that set of instructions to his original 11 apostles. So it must have been valid for them during the early Acts period when they were fulfilling the GC. But now, we don't follow those instructions, even though it was part of the GC found in the book of John.

So do you now agree that not all of the instructions in the GC is valid for the church today?

The OP is taking the verse out of context. No one but God can forgive sin. Jesus said if you accept Him you will be saved, if you reject Him you are lost. The disciples could therefore say one is lost or saved based on CHRIST'S death and forgiveness of sin. They themselves could not forgive sin, they themselves were not sinless.

The Jews are not an evangelistic people. I could never understand that. Well, actually I could, but only to a point.
How Christians do not want to share the wonders that Jesus has done for them is beyond me. The way I see it, it's kinda like when you are in love, and want to tell the world about that person. I have found (I am making a generalization, there re genuinely shy and quiet and insecure people who just have a hard time speaking up, whatever the subject), but I have come to the conclusion, generally speaking, that if one is consistently not talking about Jesus, to someone, anyone, it doesn't have to be out in public to strangers, then I question the depth of their relationship with Him.

Exactly!!

Romans 10

For there is no distinction between Jew and Greek; for the same Lord is Lord of all, abounding in riches for all who call on Him; for "Whoever will call on the name of the Lord will be saved." How then will they call on Him in whom they have not believed? How will they believe in Him whom they have not heard? And how will they hear without a preacher?
How will they preach unless they are sent? Just as it is written, "HOW BEAUTIFUL ARE THE FEET OF THOSE WHO BRING GOOD NEWS OF GOOD THINGS!"

I agree. I think that is what he was saying...unless I am misinterpreting his remarks.

You're making the verse say something it didn't. As I said above, based on acceptance of Christ's forgiveness for ones sins one is either saved or lost. A person who is not sinless themselves cannot forgive another's sins. Even Jesus' own mother needed a Savior. They were never able to forgive sin, so you're not making any point here. Nothing to agree on.

The Jews are not an evangelistic people. I could never understand that.

Well according to Christ they traveled over land and sea to make one convert to Judaism. So you are mistaken.

Woe unto you, scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more the child of hell than yourselves. (Mt 23:15)

As stated many times here, there are people who rightly divide the word according to different dispensations.

You are of course free to reject that method of understanding the Bible.

So what do you think that verse is actually saying, care to share how you would interpret that verse?

Honestly, no disrespect, but you really belie that the Jews are evangelizing people?

The Messianic Jews (Hebrew Christians) are evangelizing their own people, and that's the only thing that counts.

And that verse was definitely not taken out of context. According to their lights the scribes and Pharisees in the days of Christ were "proselytizing" (which is equivalent to Christian evangelism), but as Christ said, totally worthless. So if one is mistaken, one should admit it without further discussion.

Some arguments why

1. The term "Great Commission" was never in the Bible, and Bible translators only added that in the heading.
2. Matthew's version, the most popular one, had Jesus instructing them to teach others to follow "everything" he has taught them, which if you read the entire Gospel of Matthew, had instructions which are clearly incompatible with Paul's Gospel. "Sell all you have'. 'do not go into the Gentiles' 'I was only sent to the lost sheep of Israel', 'Follow what the Pharisees instruct you as they sat on Moses's seat' etc.
3. John's version had an instruction that only the Roman Catholic church practiced, 20:23 If you forgive the sins of any, they are forgiven them; if you withhold forgiveness from any, it is withheld.” No Protestant church that I know of practice this.
4. Mark's version said you must believe AND be baptized to be saved, safe to say, not many churches follow the latter. Furthermore, no church would tell their Gentile believers to pick up serpents as a sign now.
5. Luke's version say you must start from Jerusalem, obviously from what Paul said in Romans 9-11, that avenue is now closed since the vast majority of the Jews rejected the gospel.

What do the rest of you think?

In my opinion, there is a big difference between those who speaks with human wisdom and Christians whose wisdom is from God (spiritual).

Noah built a physical arc to save eight souls and everything in it but Jesus built a spiritual arc to save a multitude.

Are we to build an arc today as it was commanded to Noah in the past? If we belong to the body of Christ then we are His fellow workers in building that spiritual arch.

Just a matter of physical(worldly) against spiritual wisdom.

NIV1984 James 3:13-18
Two Kinds of Wisdom Who is wise and understanding among you? Let him show it by his good life, by deeds done in the humility that comes from wisdom. But if you harbor bitter envy and selfish ambition in your hearts, do not boast about it or deny the truth. Such “wisdom” does not come down from heaven but is earthly, unspiritual, of the devil. For where you have envy and selfish ambition, there you find disorder and every evil practice. But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere. Peacemakers who sow in peace raise a harvest of righteousness.

Have you considered the body of Christ as the new creation IN CHRIST in starting this thread?

NIV1984 Ephesians 2:11-22
One in Christ Therefore, remember that formerly you who are Gentiles by birth and called “uncircumcised” by those who call themselves “the circumcision” (that done in the body by the hands of men)— remember that at that time you were separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of the promise, without hope and without God in the world. But now in Christ Jesus you who once were far away have been brought near through the blood of Christ. For he himself is our peace, who has made the two one and has destroyed the barrier, the dividing wall of hostility, by abolishing in his flesh the law with its commandments and regulations. His purpose was to create in himself one new man out of the two, thus making peace, and in this one body to reconcile both of them to God through the cross, by which he put to death their hostility. He came and preached peace to you who were far away and peace to those who were near. For through him we both have access to the Father by one Spirit. Consequently, you are no longer foreigners and aliens, but fellow citizens with God’s people and members of God’s household, built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone. In him the whole building is joined together and rises to become a holy temple in the Lord. And in him you too are being built together to become a dwelling in which God lives by his Spirit.

Can we forgive sins? Yes we were told to forgive those who sinned against us because the Spirit working in us leads us to forgive sins as He is a forgiving God.
