“dissolving the P/B team” was my conjecture, and I should have said so. But the team really was dissolved, and Barnabas was not heard of thenceforth from the John Mark episode. Interesting that Mark became essentially Peter’s amanuensis later on. Somebody had/has a burr under the saddle, and Peter has been it for two millenia.
A fight in the team dugout btwn two good and determined (Barnabas determined to take with them John), men, likely with different gifts besides commonly held ones. Perhaps the same kind of heart that led Barnabas seek out Paul and bring him to the wary disciples is what led him to see Paul as too demanding, but Paul the leader could not risk taking on a solider who went AWOL once, and i Scripture affirms his leadership.
The paradox is that while Acts is mostly about reconciling corporate division (though it did not end, yet one side was now officially reproved), it also testifies to division btwn a team of of men whose mission and testimony helped rectify this corporate division.
Yet as often with Prot divisions btwn those who love God and His truth, this cell division likely resulted in a greater increase of souls being reaped, though such should come out of core unity of heart and mind.
But it was Peter who wrote,
And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you; As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction. (2 Peter 3:15-16)
Thus the first "pope" foretold of so much RC (if not alone) abuse of Scripture.
