No offense but..Fr Gerald Culleton and others need to read the Bible and see that the 4 horsemen are about to ride (Rev. 6, Rev. 6-19.) and the church taken out to be with their Savior (John 14:6, 1 Thess 4:13-18)
Destroy the Church no, christian civilization yes... that is why Christ comes again (Rev. 19:11-21) Christ has died, Christ has risen... Christ will come again (Rev. 19:11-21) also He will come in glory to judge the living and the dead.... and His kingdom will have no end and also Thy Kingdom come Thy will be done. When His kingdom is established then no will over throw it FOREVER! Amen (Dan. 2:44-45, Dan. 2:13-14, Matt. 25:31-45)
Fast forward to now and it's not hard to see the world through the Scripture you've quoted. Event by event, warning by warning, prophecy by prophecy, we move closer to that day when He returns as Judge.
All of Scripture will be fulfilled. In the meantime, some parts should be taken as a warning for those foolish enough to repeat the mistakes of our ancestors.
Like you've pointed out, I don't think we've heeded the warnings. The Church may not be destroyed, but it can be corrupted through human weakness and worldly passions. Looking around at the mess humanity's made of things I'd say we're overdue for a spring cleaning.
No matter which side you're on, corrections can be rough either way, so it's best to tie down to the only rock solid anchor.
