Plato’s Timaeus concerns the overflowing goodness of God and the creation of the world. This helped many medievals, including St. Bernard, to explain the goodness and hierarchy of the beauties of a nature redeemed by Christ. Dr. William Marra explains the problems that came from the possible use of the Timaeus by Gnostics, and Plato’s inability to grasp creation ex nihilo.
