Christians believe that on the Last Day, bodies will be resurrected and lives will be judged. But what does it mean for a body to resurrect - will it, for example, resurrect in the physical condition it was in at death? - and what does a final judgment involve? Are the only alternatives doom or salvation?

The 4th-century theologian and mystic Gregory of Nyssa discussed these questions with his dying sister Macrina and shared their conclusions in his "On the Soul and Its Resurrection," written around AD 380. Fr. Kerry offers an overview of the book , with a side trip through C.S. Lewis' Narnia.
