Into the Wardrobe

Welcome to the Wardrobe, stepshep.
The only thing that comes to mind are parenthetical comparisons between Lewis (low) and TS Eliot (high), but these are made by editors and biographers not Lewis himself. I found seven pertinent references under Anglo-Catholicism in Fr. Walter Hooper's CS Lewis: A Companion & Guide

I'm not sure if he goes into the differences anywhere, but I know he mentions the distinction in the preface to Mere Christianity.

Off-hand, I can only think of a brief mention of "Low Church/High Church" in "The Screwtape Letters". Even here, it's not really a discussion of the difference, but more of a advice from Screwtape to Wormwood on how to use differing opinions to stir up trouble.

Remember, Lewis was a devotee of the Church of England. And the Church of England has often had various movements going on within it that were not exactly sanctioned by the church heirarchy. John Wesley's "Methodist Movement" comes to mind. Throughout Wesley's life, the Methodists in England remained a part of the Church of England. Even in America, they didn't seperate until after the colonies gained independence.

So, the "High Church/Low Church" debate Lewis was referring to was not a dispute between different denominations, but a dispute between differing parties within the Church of England.

I have no idea if such a debate still goes on. Perhaps an Anglican or two can post some thoughts on this.
