Dates: c. 1964 (Letters to Malcolm) · Wikipedia
Summary: C. S. Lewis (1898–1963), the Oxford and Cambridge scholar and lay Anglican apologist, is the
timeline's modern Protestant witness for a purified purgatory. In Letters to Malcolm: Chiefly on Prayer
(published posthumously in 1964) he affirms, plainly and without hedging, that he prays for the dead and believes in
purgatory — while sharply repudiating the late-medieval retributive version the Reformers rightly rejected
(the "Romish doctrine … as that Romish doctrine had then become," with its penal torments and traffic in indulgences,
as in Thomas More's Supplication of Souls and Bishop Fisher). His purgatory is not a debtor's prison but a
cleansing the redeemed soul itself desires: a final washing before the presence of God.
Of course I pray for the dead. The action is so spontaneous, so all but inevitable, that only the most compulsive theological case against it would deter me.

Lewis grounds the practice not in a doctrine of purgatory but in the communion of love: "At our age the majority of those we love best are dead. What sort of intercourse with God could I have if what I love best were unmentionable to Him?" Prayer for the dead, for him, is the natural overflow of charity that does not stop at the grave.
I believe in Purgatory. Mind you, the Reformers had good reasons for throwing doubt on "the Romish doctrine concerning Purgatory" as that Romish doctrine had then become.

Lewis grants the Reformation case its force: the purgatory the Reformers attacked — a place of penal suffering, entangled with the sale of indulgences and the commerce of relieving souls, the version he associates with More's Supplication of Souls and Fisher — deserved their "doubt." What he recovers is a different and, he argues, older idea: a purgatory of cleansing, not punishment.
Our souls demand Purgatory, don't they?
— Letters to Malcolm, Letter 20, cited at churchpop.com. Lewis pictures the saved soul, brought at last into the divine presence, asking itself to be made clean before entering — "With submission, sir, and if there is no objection, I'd rather be cleaned first." The cleansing is not a penalty imposed from without but the longing of a soul that cannot bear "with its darkness to affront that light" (he points to the saved soul of Newman's Dream of Gerontius). This is purgatory as completion of sanctification, not satisfaction for a debt.
