Read it through once
It is not even that the poets were not devout Christians: for a pattern of orthodoxy of principle, and sincere piety of feeling, you may look long before you find a poet more genuine than Samuel Johnson. Yet there are evidences of a deeper religious sensibility in the poetry of Shakespeare, whose belief and practice can be only a matter of conjecture. And this restriction of religious sensibility itself produces a kind of provinciality (though we must add that in this sense the nineteenth century was more provincial still): the provinciality which indicates the disintegration of Christendom, the decay of a common belief and a common culture. It would seem then, that the eighteenth century, in spite of its classical achievement—an achievement, I believe, which still has great importance as an example for the future—was lacking some condition which makes the creation of a true classic possible. What this condition is, we must return to Virgil to discover.
