This is why I left you in Crete, so that you might put what remained into order, and appoint elders in every town as I directed you - if anyone is above reproach, the husband of one wife, and his children are believers and not open to the charge of debauchery or insubordination. For an overseer, as God’s steward, must be above reproach. He must not be arrogant or quick-tempered or a drunkard or violent or greedy for gain, but hospitable, a lover of good, self-controlled, upright, holy, and disciplined. He must hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it.I am sure I have about 3,000 words on what I am about to say next, but I'm going to say only this and leave the rest to the meta:
Notice that Paul here instructs Titus to appoint elders in every town and not watchbloggers. That is: the focal point and center of discernment ought to be in the local church. If your counter-concern is that local churches today lack discernment (and this may be a valid concern), I suggest that the place to fix that is in the place God ordained and not everywhere else but that place.
There is plenty of nuance lacking in this post. We can work all of it out in the meta.
