ABSTRACT

Aquinas’s understanding of God as eternal is foundational for very many of his theological views. The concept of eternity, as Aquinas understands it, also makes a significant difference to a variety of issues in contemporary philosophy of religion, including, for instance, the apparent incompatibility of divine omniscience with human freedom and of divine immutability with the efficacy of petitionary prayer; but because the concept has been misunderstood in the current philosophical discussion or cursorily dismissed as incoherent, for a long time it did not receive the attention it deserves from contemporary philosophers.1 In this chapter, I expound and attempt to defend Aquinas’s interpretation of the concept of divine eternity.
