“’To be deep in history is to cease to be Protestant.’ But the effect is the same nonetheless.”
It’s vastly different. I’m not Catholic and I’m not protestant. Maybe Lewis meant all non-protestants were Catholics but if he did, he was flat wrong, and was reading the wrong history books.
If you’re not Catholic, and you’re not Protestant, does that make you Orthodox? I suspect the manner in which I quoted it leaves that possibility as well.
BTW, the quote was John Henry Cardinal Newman, not Lewis.
It was Newman, not Lewis. And I think where he was going with that is that a close reading of the history of the Church and a history of the Reformation is very enlightening.
