An aspect of Lewis that I found interesting was that he and Tolkien knew each other through their involvement in Old English literature, and that Lewis came to faith not all that long after Tolkien. But whereas Tolkien joined the Roman Catholic Church, Lewis felt more at home as an Anglican.
(I cannot recall offhand what particular denomination he was raised in, if any.)
My own background was in the Free Churches, but on coming to faith (after several years of militant agnosticism) I also found myself at home as an Anglican.
