Medievals experienced the divine as far more present in their daily lives. As it has been for most people, Christian and otherwise, throughout history, religion was everywhere, and— this is crucial— as a matter not merely of belief but of experience. In the mind of medieval Christendom, the spirit world and the material world penetrated each other. The division between them was thin and porous. Another way to put this is that the medievals experienced everything in the world sacramentally.
