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. When they had ordained them elders - Elder seems to be here the name of an office. These were all young or new converts, and yet among them the apostles constitute elders. They appointed persons the most experienced, and the most advanced in the Divine life, to watch over and instruct the rest. But what is the meaning of the word χειροτονησαντες, which we translate ordained? The word ordain we use in an ecclesiastical sense, and signify by it the appointment of a person to an office in the Church, by the imposition of the hands of those who are rulers in that Church. But χειροτονια a signifies the holding up or stretching out the hand, as approving of the choice of any person to a particular work: whereas χειροθεσια signifies the imposition of hands. "Zonaras gives he proper meaning of the word in the text, in his Scholia upon the first canon of the apostles, Νυν μεν χειροτονια καλειται, κ. τ. λ. 'Nowadays, a course of prayers and invocation on the Holy Spirit, when one is initiated into the priesthood, and receives consecration, is called χειροτονια, cheirotonia, so termed because the bishop extends his hand over him whom he blesses, when he is chosen into holy orders. Anciently, the choice or suffrage was called cheirotonia; for, when it was lawful for the multitude in their cities to choose their priests or bishops, they met together, and some chose one man, some another; but, that it might appear whose suffrage won, they say the electors did use εκτεινειν τας χειρας, to stretch forth their hands, and by their hands so stretched forth, or up, they were numbered who chose the one, and who the other; and him who was elected by the most suffrages they placed in the high priesthood. And from hence was the name cheirotonia taken, which the fathers of the councils are found to have used, calling their suffrage cheirotonia.' St. Paul, 2 Corinthians 8:19, intimates that St. Luke was thus appointed to travel with him χειροτονηθεις ὑπο των εκκλησιων, who was chosen of the Churches. Ignatius, in his epistle to the Philadelphians, uses the same term, πρεπον εϚιν ὑμιν, ὡς εκκλησια Θεου, χειροτονησαι επισκοπον, ye ought, as a Church of God, to choose your bishop." Much more on this subject may be seen in Sir Norton Knatchbull, who contends that cheirotonia implies simply appointment or election, but not what he calls ordination by the imposition of hands. I believe the simple truth to be this, that in ancient times the people chose by the cheirotonia (lifting up of hands) their spiritual pastor; and the rulers of the Church, whether apostles or others, appointed that person to his office by the cheirothesia, or imposition of hands; and perhaps each of these was thought to be equally necessary: the Church agreeing in the election of the person; and the rulers of the Church appointing, by imposition of hands, the person thus elected. See the note on Acts 6:6.
And had prayed with fasting - This was to implore God's special assistance; as they well knew that, without his influence, even their appointment could avail nothing.
Commended them to the Lord - To his especial care and protection.
