Why did he turn back from the work (
Ac 13:13)? Not because of homesickness, or anxiety for his mother's safety, or home duties, or the desire to rejoin Peter, or fear of the perils incident to the journey, but rather because he objected to the offer of salvation to the Gentiles on condition of faith alone. There are hints that Mark's family, like Paul's, were Hebrews of the Hebrews, and it is not without significance that in both verses (
Ac 13:5,
13) he is given only his Hebrew name. The terms of Paul's remonstrance are very strong (
Ac 15:38), and we know that nothing stirred Paul's feelings more deeply than this very question. The explanation of it all may be found in what happened at Paphos when the Roman Sergius Paulus became a believer. At that time Paul (the
change of name is here noted by Luke) stepped to the front, and henceforth, with the exception of 15:12,25, where naturally enough the old order is maintained, Luke speaks of Paul and Barnabas, not Barnabas and Saul. We must remember that, at that time, Paul stood almost alone in his conviction. Barnabas, even later than that, had misgivings (
Ga 2:13). Perhaps, too, Mark was less able than Barnabas himself to see the latter take second place.
