Commentary on the Acts of the Apostles John Calvin
Commentary on Acts they testify that they allow that which they had done. Furthermore, this was the cause why they sent Barnabas. The apostles did at that time bear all the burden of the kingdom of Christ; therefore, it was their duty to frame and set in order Churches every where; to keep all the faithful, wheresoever dispersed, in the pure consent of faith; to appoint ministers and pastors wheresoever there was any number of the faithful. The crafty wiliness of Satan is well known. So soon as he seeth a gate set open for the gospel, he endeavoreth by all means to corrupt that which is sincere, [pure;] whereby it came to pass that divers heresies brake out together with Christ's doctrine. Therefore, the greater gifts every Church hath, the more careful ought it to be, lest Satan mix or trouble any thing amongst the ignorant, and those who are not as yet established in the right faith; because it is the easiest matter in the world to corrupt corn in the blade. To conclude, Barnabas was sent to bring them farther forward in the principles of faith; to set things in some certain order; to give the building which was begun some form, that there might be a lawful state of the Church.
23. When he had seen the grace of God. By these words Luke teacheth, first, that the gospel which they had received was true; secondly, that Barnabas sought nothing else but the glory of Christ. For, when he saith that he saw the grace of God, and that he exhorted them to go forward, hereby we gather that they were well taught. And the joy is a testimony of sincere godliness. Ambition is evermore envious and malicious; so that we see many seek for praise by reproving other men, because they are more desirous of their own glory than of the glory of Christ. But the faithful servants of Christ must rejoice (as did Barnabas) when they see the gospel increase, by whomsoever God shall make his name known. And assuredly those which help one another, so that they acknowledge that all the effect which springeth thence is the work of God, will never envy one another, neither will they seek to carp [at] one another, but will, with one mouth and mind, praise the power of God.
Again, this is worth the noting, that Luke doth attribute the faith of the men of Antioch, and whatsoever was worthy [of] praise there, to the grace of God. He might have reckoned up all those virtues which might make for the commendation of men; but he comprehendeth what excellence soever was in that Church under this word grace. Lastly, we must note Barnabas' exhortation. We have already said that Barnabas did subscribe to the former doctrine which they had embraced; but lest doctrine fall away, it is most requisite that it be thoroughly imprinted in the minds of the faithful by continual exhortations. For seeing that we have to encounter continually with so many and such strong adversaries, and our minds are so slippery, unless every man arm himself diligently, it will by and by fall away, which thing infinite numbers do show to be true by their falling away. Whereas he setteth down this manner of perseverance, that they continue with purpose of heart we are hereby taught that faith hath taken deep root then when it
