Occasionally I mention my friendship with the local Pentecostal preacher; he is moving to a larger city because of his wife's health problems, and I will miss him. He is a good honest man, and while we differ, often drastically on our perception of truth, we overlook each others faults and consider ourselves brothers in serving the Lord.
The Pentecostal hierarchy he associates with has a pool of preachers that are assigned to churches throughout their jurisdiction, so he has to jump back into the pool and start over again. For a church to accept him as their preacher he must first preach for them, then they will vote whether or not he is acceptable. If after three preachers are refused by a church the ministerial association will appoint a preacher from their available pool to fill the vacancy, whether that church likes it or not.
The requirements for a preacher in his church are high; they have to meet certain qualifications educationally, and spiritually, including an ordination ceremony, and a series of tests before they are recognized as acceptable candidates to preach. I couldn't help but remind him that Jesus selected a bunch of fishermen to become Apostles that wouldn't even qualify to be in his church's preacher pool. We're still friends :)
Churches of Christ can run into problems selecting a preacher, but at least its members have the final word on who stands in the pulpit on Sunday morning. Without our stand for church autonomy we could be at the mercy of some hierarchal ministerial association paid to decide what is in our best interest...no thanks!
