In reply to Carl Vehse.

Since Lewis was an Anglican, one can make some guesses, but Lewis (as far as I know) never specifically repudiated any Lutheran doctrine. He was certainly fuzzy on grace, at least in my opinion; he did not write on baptism and probably did not see baptism as a means of grace although he had a strong view of the Lord's Supper which approaches Lutheranism or might even be identical; and he held to purgatory (against both Lutheran and Anglican positions). It's easier to say where he agreed with Lutherans, i.e. as someone rather liturgical, the Lord's Supper (to the extent he wrote on it), the need to understand the problem of sin before appreciating the solution (i.e., a fairly good understanding of Law and Gospel), similar views on eschatology, the Trinity, the atonement of Christ, the deity of Christ, and a lot more.
