I must nitpick at you in one area, however. You state, ...although Lewis was an Anglican Catholic convert." Lewis and his brother were born and raised as members of the Church of England (in Ireland). He fell away from the faith, but returned years later (a long conversation with Tolkien was key in the process). He never became a Roman Catholic, nor may he fairly be considered an Anglo-Catholic. He always believed in mere Christianity!
Yours faithfully,
Martin
BTW I never meant to imply Lewis was a Roman Catholic. Anglican and Catholic beliefs are similar on key issues. Lewis' work is used by Catholics as an example of Catholic teachings. In recent years, the Anglican church--after many years of discussion---reached rapproachment with Rome.
