Arial & Josheb: It is called systemic reformation, encompassing all areas of life. Give some thought to King Nebuchadnezzar. He was not an Israelite, yet God used him to demonstrate His power and control.....
The problem with that viewpoint is that God did not strike the Israelites insane. This op conflates what happened to Israel with what happened to Nebuchadnezzar.... and then attempts to assign God's manipulation and punishment of an unsaved non-believer to the saved,
regenerate and indwelt believers in the Church. The op also equate reform with punishment.
Through the process of sanctification, the Church is always reforming, yet there is no place in the entire New Testament where the entire Church is punished, especially not with insanity. Even the seven churches in Revelation are told their suffering is to be endured for the sake of reward and God's presence, not exile into a wilderness stripped of all its cognitive faculties.
In Matthew 12 Jesus is accused of being in league with the pagan god Beelzebub, a devil. Jesus confronts that accusation by telling his accusers they have stepped beyond the limits of God's grace by attributing the work of the Holy Spirit to the devil
(who is himself enslaved to sin by his own disobedience). There is no forgiveness for that act. Nowadays we hear a certain segment of Christendom criticizing the Church, claiming it is in need of reform because (in the case of this op) the Church is like Nebuchadnezzar. It's like the pagan Nebuchadnezzar and NOT like the unfaithful Israel who was exiled
because it has a covenant relationship with God (which Nebuchadnezzar did not have.
The Church is the temple of God in which the Holy Spirit lives and works.
It is, therefore, absolutely necessary that any and all judgment of the Church NOT attribute the work of the Holy Spirit to devils (or sin). This also means that every single preacher, teacher, and/or ordinary Christian who practices such judgment has run the risk of committing the so-called unforgivable sin

. It is not that reform is never needed. Nor is it that criticism of religious institutions is unneeded. The absolute, necessary concern is that such things never breach the boundary of attributing the sinful flesh or the influence of demons to the Spirit. Jesus hyperbolically polarized the situation with the following comment:
The one who is not with me is against me; and the one who does not gather with me scatters.
And, sadly, there is one specific sect within Christianity that does that often. It is Dispensational Premillennialism or, more generically, modern futurism. You,
@Buff Scott Jr., and most of the rest of you, have read me comment on the history of this practice before. When the sects of the Restoration developed in the 19th century they all held to a pair of core beliefs: 1) The Church is corrupt and, therefore in need of restoration, and 2) because Jesus was coming back sometime in the 19th century it was incumbent for people to join that sect and follow its teaching so as to shed the corruption and be restored to their version of a New Testament era church. This was true of all the Restoration movement sects.
The problem is they were all working from a misguided ecclesiology
(a mistaken definition of the Church). and a misguided understanding of the Church in the New Testament
(which was a very messy place). You,
@Buff Scott Jr., being a modern futurist, naturally fall prey to the misguided teaching of that theology. You, also therefore, end up practicing misguided ops like this one in which the house that God builds is compared to a pagan man God struck insane.
That is a really bad ecclesiology.
There is one more important point about Dispensational Premillennialism that contributes to the problem of mistaken attribution. Dispensational Premillennialism 1) hold to a two-people, two-kingdoms theology and 2) elevates (its) ecclesiology as a critical doctrine within Christianity when 3) the rest of Christendom does neither. For the rest of Christendom Christology and soteriology are preeminent and Israel is irrelevant to Christian ecclesiology and eschatology. God has only one people, one kingdom, and both fall within His singular divine purpose.
1 Corinthians 3:16-17
Do you not know that you are a temple of God and that the Spirit of God dwells in you? If anyone destroys the temple of God, God will destroy that person; for the temple of God is holy, and that is what you are.
Be careful judging so as not to destroy the Church. The devil wants Christians judging the Church and one another. He wants that to happen to the point of hubris
(attempting to sit on God's throne and make decisions that are the Spirit's alone). We are not Nebuchadnezzar, and God has not struck His Church insane, and He does not punish us, He disciplines us for the sake of sanctification.
