Acts 1:15

15.It was meet that Matthias should be chosen into the place of Judas, lest, through the treachery of one man, all that might seem to have been made of none effect which Christ had once appointed. He did not unadvisedly choose the twelve in the beginning, as principal preachers of his gospel. For when he said that they should be judges of twelve tribes of Israel, Luke 6:13, John 6:70; he showeth here that it was done of set purpose, that they might gather together the tribes of Israel unto one faith. But after that the Jews had refused the grace offered unto them, it was behoveful that the Israel of God should be gathered together out of all countries.

This, therefore, was, as it were, a holy number, which, if it should have been diminished through the wickedness of Judas, then should the preaching of the gospel both have had, and also have, less credit at this day, if the beginning thereof had been imperfect. (56) Although, therefore, Judas would (as much as in him lay) have disappointed the purpose of Christ, yet nevertheless it stood firm and stable. He perished as he was worthy, yet did the order of the apostles remain whole and sound.

The company of names It is uncertain whether he meaneth the men who only have the name properly, seeing the women are comprehended under the name of the men; or whether he taketh names simply for all the heads, as the Hebrews call them souls. This may also be called in question, whether they were wont daily to frequent that parlor in which the apostles did dwell, or they did continually dwell there with them. For the place was scarce able to contain so great a multitude, to serve them for all necessary uses. Surely it seemeth to me a thing more like to be true, that Luke doth in this place express the number of them, that we may know that they were all gathered together when Peter made this sermon. Whereby we may guess that they were not always present there. Although I dare not affirm any certain thing concerning this matter, yet being moved with a probable conjecture, I do rather lean unto this part, that the church was gathered together them because they had to intreat of a serious matter, and to this end also tendeth this word rising, [standing up.]
