Biblically, we see in the New Testament, elders/pastors basically appointed by the faithful to lead local congregations. Those men were entrusted with "feeding" Christ's sheep. They were appointed to be leaders who literally ran the affairs of each local church. Church members (saints) were expected, so long as that elder/pastor remained qualified and faithful to the work, to submit to their authority, and to serve along side them willingly and with joy in the Kingdom work.
