Rev. Buchanan, by expecting "elders to be competent at some level to teach in our churches, per 1Tim.3:2" aren't you sharply departing from Hodge's view? Somewhat related, do you understand the office of ruling elder to be by divine appointment or practical necessity?
In answer of the first, I suspect I may be departing sharply; but I've already admitted that I'm not in lock-step agreement with him, although I find much about his views to appreciate.
I'll stick my neck out for
de jure Presbyterianism, and state that I believe the office of elder to be by divine appointment. I think its origins are partly to be found in a natural office of the patriarch, and heads of the tribes and clans of Israel. I believe that it receives refinement starting with the wisdom expressed from Jethro, Moses father-in-law, concerning the duties of ruler/judge of the people, Ex.18:17-23.
Moses (the mediator) chose him men from among the people, but as M.Poole points out, "Moses chose them not solely, but together with the people, as appears from Dt.1:13."
9 At that time I said to you, 'I am not able to bear you by myself.... 12 How can I bear by myself the weight and burden of you and your strife? 13 Choose for your tribes wise, understanding, and experienced men, and I will appoint them as your heads.
So, here is the mediator of the Old Covenant calling men into office, and the mechanism for effecting the choice is a popular selection--akin to the way in which our elders are chosen today.
Poole again points out that Moses acted on Jethro's counsel after he was satisfied that God had approved this notion, demonstrating that it did not proceed from nothing more than human wisdom and expediency, "Moses did all that he had said, not immediately, but after he had received God’s approbation, Num.11:16."
16 Then the LORD said to Moses, "Gather for me seventy men of the elders of Israel, whom you know to be the elders of the people and officers over them, and bring them to the tent of meeting, and let them take their stand there with you..... 24 So Moses went out and told the people the words of the LORD. And he gathered seventy men of the elders of the people and placed them around the tent. 25 Then the LORD came down in the cloud and spoke to him, and took some of the Spirit that was on him and put it on the seventy elders. And as soon as the Spirit rested on them, they prophesied.
We believe the church of the New Testament is nothing but the church of the Old Testament continued, with due allowances for changes in the conditions upon which it is settled. These men were denominated "elders" of old. I do not believe that that title has been transferred in the NT only to ministers.
