No, not all Protestants do that. Where in the world did you find that idea? None of the churches I have attended have done that. Not a one. You need to do some research. I knew Osteen was a fake the first time I came across him. There are others, too. You should have attended a few of the hell and brimstone churches I attended as a kid. None of this feel good junk. That is not what the Bible teaches.
“No, not all Protestants do that.”
Yes, they do - maybe not as bad as Osteen, but all do in their own Protestant way.
“Where in the world did you find that idea?”
All over - from the mouths of Protestants, posts here at Fr, Protestant books. The mistake you’re making apparently is that you think touchy-feely only applies to Osteen’s saccharine gospel is an absolute outside of every other Protestant sect. It isn’t. It’s more or less just one end of a Protestant spectrum of touchy-feely subjectivism.
“That is not what the Bible teaches.”
It sure isn’t - but it is what Protestantism teaches.
