But ecclesiology? "High brow." "Arcane." Maybe even "trifling over words."
Another name for ecclesiology is "church truth." But the lukewarm church of the last days doesn't need "church truth," either. Why not? "Because we've always done things this way," that's why.
This highlights the fact that "church truth" largely concerns traditions and not doctrines. But most of us never question our traditions, secular or sacred. We just do them. In the church these traditions owe their legitimacy, not to the fact that these traditions are found in the New Testament, but to the fact that they have been repeated for so long. Due to repetition the human traditions have acquired the legitimacy due the apostolic traditions found in the New Testament.
So when a Christian like Thomas Milner or G.H. Lang writes about church truths, the reaction of the masses is, "Why are they making such a big deal out of this?" It seems like much ado about nothing to those accustomed to years of Sunday sermons, offering plates to benefit the clergy and the landscaping of the grounds, "junior pastors," "the sanctuary," "pulpit supply," etc., etc.
The fact is the average Christian has never been taught anything about church truths except perhaps that the fact Jesus gave gifted men to the churches (Ephesians 4) somehow implies that when a young man hears "a calling" to the ministry, it is because he is one of those Christ gave to the church! Or that the "pastoral epistles" prove that young men can be pastors in churches! Or that the churches' legion of young pastors are also elders, "in a manner of speaking, of course."
What sophistry! It is false teaching. It is heresy. (I do not say it is damnable heresy. The NT distinguishes the one from the other. I do not say these teachers are all going to hell.) One expects sophistry from atheists. But from Christians?
The fact of the matter is, most Christians know almost nothing about church truths. This is the apostasy. It isn't that the truth is never taught in the churches. It surely is, in various places. But the order and polity of the churches is, and was long ago, ruined. Consequently believers and unbelievers are intermixed in the churches, and it is often hard to tell the difference. And the believers do not grow as they ought, unto perfection, "...for the work of the ministry, for the edifying of the body of Christ."
But this is all just blowing smoke, isn't it? Ah, but one day all believers will be judged by Christ for rewards, and all the idle professors will be judged for condemnation. We do not yet see clearly.
