The Generic Fallacy, the ascribing to the whole what may be the case with some of the part (or parts), is one that all Christians ought to strive to avoid, by the grace of God.
Take anything good, and you can practically destroy it, by citing some foolish abuse of it, by someone who (allegedly, at least) holds to that good thing.
Ecclesiocentricity, the simple doctrine that Christ has chosen to exalt Himself, first and foremost, in His church, can be slandered, by the supposition that there may be some wayward souls who wish to have “church” without Jesus.
We’ve talked about schooling a bit in these various posts. One might wrongly condemn public education, because some who avail themselves of it are atheists, or proponents of Darwinian evolution.
On the other hand, someone might wrongly besmear homeschooling, on the basis that some homeschoolers despise Christ and stand aloof from His church.
But, are any of these reasons to condemn the whole, based on the naughtiness of some of the parts? Certainly not.
Let us continue to seek to be fair-minded and level-headed, all for the glory of God.
