I don't know about sainthood, but G K Chesterton (a member of the Maggie's pantheon) certainly deserves to be read and to be remembered.
... when he was right, he was prophetically right. Fearing and detesting the centripetal, black-hole suck of the almighty modern Self, he faced the other way: into the fact of Creation. There is a reality outside the mind, Chesterton insisted—and part of his energy was his innocent, unflagging astonishment that he had to keep on making the point. To us, the great solipsists, for whom the recognition of another human being requires a galvanic imaginative act, he speaks very directly.
