Worshiping the God of Corn and Oil and Wine

"The thought at the back of all this negative spirituality is really one that is forbidden to Christians. They, of all men, must not conceive spiritual joy and worth as things that need to be rescued or tenderly protected from time and place and matter and the senses. Their God is the God or corn and oil and wine. He is the glad Creator. He has become himself incarnate. The sacraments have been instituted...After that we cannot really be in doubt of his intention. To shrink back from all that can be called Nature into negative spirituality is as if we ran away from horses instead of learning to ride. There is in our present pilgrim condition plenty of room (more room than most of us like) for abstinence and renunciation and mortifying our natural desires. But behind all asceticism the thought should be, 'Who will trust of with the true wealth if we cannot be trusted even with the wealth that perishes?' Who will trust me with a spiritual body if I cannot control even an earthly body? These small and perishable bodies we now have were given to us as ponies are given to schoolboys. We must learn to manage: not that we may someday be free of horses altogether, but that someday we may rise bare-back, confident and rejoicing, those greater mounts, those winged, shining and world-shaking horses which perhaps even now expect us with impatience, pawing and snorting in the King's stables. Not that the gallop would be of any value unless it were a gallop with the King; but how else--since he has retained his own charger--should we accompany him?"
