Yes--Lewis remained a Protestant, albeit a highly orthodox one. He always admired the Catholic church, though, and his book "Mere Christianity" was an effort to find the common ground between orthodox Protestants and Roman Catholics.

Although Tolkien always hoped that Lewis would become a Catholic, the two remained great friends throughout their lives.

Thanks for the edification on that point.

Now, the oblique criticism of mainline (Protestant) Christian churches made in the "Screwtape Letters" makes a little bit more sense.
