Acts 6
1In those days when the number of disciples was increasing, the Grecian Jews among them complained against the Hebraic Jews because their widows were being overlooked in the daily distribution of food. 2So the Twelve gathered all the disciples together and said, "It would not be right for us to neglect the ministry of the word of God in order to wait on tables. 3Brothers, choose seven men from among you who are known to be full of the Spirit and wisdom. We will turn this responsibility over to them 4and will give our attention to prayer and the ministry of the word."
5This proposal pleased the whole group. They chose Stephen, a man full of faith and of the Holy Spirit; also Philip, Procorus, Nicanor, Timon, Parmenas, and Nicolas from Antioch, a convert to Judaism. 6They presented these men to the apostles, who prayed and laid their hands on them.
I think we can discern several principles from this passage:
1) the congregation chose their officers
2) the officers are men
3) they are ordained, set apart, by laying on of hands
It does not appear that voting or selection was restricted to heads of household only, and it does appear the congregation had say, perhaps best understood in the sense of confirming God's appointment, of those who rule over them.
