“And when they had ordained them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they believed.”
King James Version (KJV)
14:23 When they had ordained them presbyters in every Church - Out of those who were themselves but newly converted. So soon can God enable even a babe in Christ to build up others in the common faith: they commended them to the Lord - An expression implying faith in Christ, as well as love to the brethren.
Ac 14:23 And when they had ordained them elders. Observe (1) that elders were not appointed as soon as the churches were planted; time must be taken so as to know what men were fitted for the office; (2) that elders were not appointed to preside over a district, but "in every church"; (3) that there was a plurality; (4) that they were set apart with fasting, prayer, and imposition of hands. It is not here stated who selected the men, but from Ac 6:6 we would infer that they were chosen by the church under the advice of the apostles.
