You certainly have a right to express your opinions about how church warning and discipline should or should not take place.
Unfortunately, the Holy Spirit, through the Bible, does some general church-bashing throughout
Revelation 2 and
Revelation 3.
Actually, I'd say the Spirit speaks correctly in those letters, and doesn't condemn the righteous with the wicked.
I wouldn't compare men's overgeneralizations to the Spirit's messages to the churches, and to whomever will hear.
When God criticizes Israel, or the churches, or whomever He may criticize, He does so with accuracy. I don't see that kind of accuracy in the sloppy statements flung around forums. But that's just me, like you say!
Saying something like, "Western Christianity is gone to the dogs", or whatever, is to me a vanity. Empty of meaning being false on it's face. There is no such thing as "western Christianity", and if there were, I daresay no one with full faculties would declare them all in agreement. Characterizations like that don't serve any meaningful purpose other than to make the speaker feel better for being it's judge.
Christianity is not bad, not corrupt, whatever. Christians come in all sorts, and many who are not claim the title anyway. People are corrupt, not Christianity, and we should not judge all people based on our opinions of our perceptions of some people. It's overgeneralizing, and maybe we don't really know what we're talking about in all cases.
Much love!
