2Co 12:12 [BSB] The true marks of an apostle—signs, wonders, and miracles—were performed among you with great perseverance.
Yet there are also warnings:
Matt 24:24 [BSB] For false Christs and false prophets will appear and perform great signs and wonders that would deceive even the elect, if that were possible.
And Jesus commended the church of Ephesus:
Rev 2:2 [BSB] I know your deeds, your labor, and your perseverance. I know that you cannot tolerate those who are evil, and you have tested and exposed as liars those who falsely claim to be apostles.
So, how do we test (1The 5:21) these "super apostles"? Just prior to this, Paul wrote:
2Co 11:4-5 [BSB] For if someone comes and proclaims a Jesus other than the One we proclaimed, or if you receive a different spirit than the One you received, or a different gospel than the one you accepted, you put up with it way too easily. I consider myself in no way inferior to those “super-apostles.”
So, these “super-apostles” proclaim:
• Another Jesus,
• A different spirit,
• A different gospel.
… and this harkens back to Deuteronomy:
Deu 18:21-22 [BSB] You may ask in your heart, “How can we recognize a message that the LORD has not spoken?” When a prophet speaks in the name of the LORD and the message does not come to pass or come true, that is a message the LORD has not spoken. The prophet has spoken presumptuously. Do not be afraid of him.
But that was not enough, because God also says:
Deu 13:1-3 [BSB] If a prophet or dreamer of dreams arises among you and proclaims a sign or wonder to you, and if the sign or wonder he has spoken to you comes about, but he says, “Let us follow other gods (which you have not known) and let us worship them,” you must not listen to the words of that prophet or dreamer. For the LORD your God is testing you to find out whether you love Him with all your heart and with all your soul.
It would appear that the "true marks of an apostle" are fine, but the apostle's message must be tested against what God has said in His written word.
