“Now they which were scattered abroad upon the persecution,” etc. (Recapitulation.) Do you mark how even in the tribulation instead of falling to lamentations and tears, as we do, they give themselves up to a great and good work? “Travelled as far as Phenice, and Cyprus, and Antioch,” and there with more security preached the word. “And some of them, which were men of Cyprus and Cyrene,” etc. And they did not say, “(What), we, Cyrenians and Cyprians, to attack this splendid and great city!” but trusting in the grace of God, they applied themselves to the work of teaching, nor did these (Gentiles) themselves think scorn to learn anything of them. Mark how by small means all is brought about: mark the preaching how it spreads: mark those in Jerusalem, having like care for all, holding the whole world as one house. “They heard that Samaria had received the word, and” to Samaria they send the Apostles: they heard what had befallen at Antioch, and to Antioch they send Barnabas: they also send again, and (these) prophets. For the distance was great, and it was not meet the Apostles at present should separate from thence, that they might not be thought to be fugitives, and to have fled from their own people. But then, almost precisely, is the time of their parting from Jerusalem, when the state (of the Jews) was shown to be past remedy, when the war was close at hand, and they must needs perish: when the sentence was made absolute. For, until Paul went to Rome, the Apostles were there (at Jerusalem). But they depart, not because afraid of the war— how should it be so?— seeing those they went to, were those that should bring the war: and moreover the war breaks out only after the Apostles were dead. For of them (the Apostles) says, “The wrath has come upon them unto the end.” The more insignificant the persons, the more illustrious the grace, working great results by small means.— “And he exhorted them to cleave unto the Lord, for he was a good man.” (v. 23, 24.) By “good man,” I take it, he means one that is kind, (χρηστὸν) sincere, exceedingly desirous of the salvation of his neighbors— “for he was a good man, and full of the Holy Ghost and of faith. To cleave unto the Lord with purpose of heart” (this is said): with encomium and praise. “And much people was added unto the Lord:” for like rich land this city received the word, and brought forth much fruit. “Then departed Barnabas to Tarsus,” etc. But why did he take him off from Tarsus and bring him here? Not without good reason; for here were both good hopes, and a greater city, and a great body of people. See how grace works all, not Paul: by small means the affair was taking its commencement. When it has become difficult the Apostles take it up. Why did they not before this seen Barnabas? Because they had enough to do (ἠ σχόληντο) with Jerusalem. Again they justified themselves to the Jews, that the Gentiles were receiving (προσελάμβανε) the word, even without enjoying so great attention. There is about to be a questioning: therefore the affair of Cornelius forestalled it. Then indeed they say, “That we to the Gentiles, and they to the Circumcision.” Observe, henceforth the very stress of the famine introduces the fellowship on the part of the Gentiles, namely, from the alms. For they receive the offerings sent from them.
“Now they which were scattered abroad,” etc. and not as we who pass our time in lamentations and tears, in our calamities; but with more fearlessness they passed their time, as having got to a distance from those hindering them, and as being among men not afraid of the Jews: which also helped. And they came to Cyprus, where they had the sea between them, and greater freedom from anxiety: so they made no account of the fear of men, but (still) they gave the precedence to the regard of the Law: “they spoke to Jews only. But there were in Antioch certain men of Cyprus and Cyrene:” these, of all others, least cared for the Jews: “who spoke unto the Greeks, preaching the Lord Jesus.” Probably it was because of their not knowing Hebrew, that they called them Greeks. And “when” Barnabas, it says, “came and had seen the grace of God,”— not the diligence of men— “he exhorted them to cleave unto the Lord”: and by this he converted more. “And much people was added unto the Lord.” Why do they not write to Paul, but send Barnabas? They did not yet know the virtue of the man: but it is providentially ordered that Barnabas should come. As there was a multitude, and none to hinder, well might the faith grow, and above all because they had no trials to undergo. Paul also preaches, and is no longer compelled to flee. And it is well ordered, that not they speak of the famine, but the prophets. The men of Antioch also did not take it amiss that they sent not the Apostles, but were content with their teachers: so fervent were they all for the word. They did not wait for the famine to come, but before this they sent: “according as each had the ability.” And observe, among the Apostles, others are put in charge with this trust, but here Paul and Barnabas. For this was no small order (οἰκονομία) of Providence. Besides, it was the beginning, and it was not fit they should be offended.
