I think any institution that controls so many people and teaches them contrary to the scriptures that only the leaders can and will be indwelt with the Holy Spirit, that the God of creation shares his sovereignty with someone outside of the trinity, and that good works is required for salvation is intrinsically evil...
That is a symptom of shadow-laden thinking. When you trace how the blessings of God flow, then you see high light and low light situations. And you can work with the low light situations to bring them more light without damning them to hell....
Nobody’s talking about telling Catholics, by the way, that the very best place for them to worship is where they are. But building the spiritual bridges takes time. Light leads them on. Railing at them doesn’t. We don’t have a situation which is as “in extremis” as the WoB described in the book of Revelation. THAT Whore will forbid ANY semblance of genuine Christian worship... please note that the Roman Catholic institution has not quite managed to do that.
