I’ve read many of his books. I appreciate his apologetics on the Moral Law, and his “The Abolition of Man” is probably my favorite. While I was at Cambridge, I met a few of his students, although I was not a member of Lewis’ college. Lewis is your typical “broad and hazy” Anglican layman when it comes to theology. He is a gifted writer and philosopher. This helps explain his popularity among a broad spectrum of theological beliefs. Although Lewis was friends with a number of Roman Catholics, he was liturgically somewhere between Evangelicalism and Methodism.
But how you can say he is on the Evangelical/Methodist continuum perplexes me. What Evangelical or Methodist did you ever meet that believed in either Purgatory or the Real Presence? My dear grandfather-in-law was a Methodist minister, and either of those doctrines would have curled his hair. And Lewis as an Evangelical is about as likely as Anthony Trollope as one. I would think the shadowy Presbyterianism of the Church of Ireland a far more likely influence on his Anglicanism (especially after reading The Pilgrim's Regress).
