I understand what you are saying, but I have been getting a different thought over the last several years. The Idea has come to me that in the early church that the ministry of the individual groups were multipul and not singular. Made up of several persons not a singul person.
Eph 4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
Eph 4:12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
Eph 4:13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
Eph 4:14 That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;
Note Paul teaches us that God gave.... God did not give the church to the ministry but the other way around. Paul list the ministry commanly known as the five fold ministry. there is a distinct purpose for them.
For the perfecting of the saints, for the work of the ministry the word for perfecting is better translated equiping, we have this idea that it is the minstrys job to straighten us the saints out. I don't think this is so
Php 2:12 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
as we are instructed we are to work out our own salvation so what is the ministrys job?
For the equiping of the saints, for the work of the ministry, for the edifying of the body of Christ: Just as God gave the gifts of the spirit for the edifying of the body of Christ which is the church, God gave the ministry for the edifing of the body of Christ. Is there a single direct leader in the church I don't think so. Are we ready for things to be the way God disigned it to be I think we are closer then ever before. Several churches I have fellowshiped with are now set up much this way with the pastors as the main figure head but the church is actual controled by the ministring body.
And finallyyou referanced OT alot from the point of veiw that you are looking from but when you begin to see things from a differant point of view you see even the way OT examples look differently. At least I do. I am not trying to start and argument but I just wanted to throw a different point of view in here.
