In a true church of Christ gathered together by God, not only into the belief of the principles of Truth but also into the power, life and Spirit of Christ, the Spirit of God is the orderer, ruler and governor, as in each particular, so in the general. And when they assemble together to wait upon God, and worship and adore him; then such as the Spirit sets apart for the ministry, by its divine power and influence opening their mouths … these are thus ordained of God and admitted into the ministry; and their brethren cannot but hear them, and receive them. And so this is not monopolised by a certain kind of men, as the clergy … and the rest to be despised, as laity; but it is left to the free gift of God to choose any whom he sees meet thereunto, whether rich or poor, servant or master, young or old, yea male or female.
