The idea of a collection of SF about religious experience is so intriguing that the mere competence of two out of three of these stories proves disappointing. Silverberg provides a routine tale of an astronaut, back from Mars where his comrades died, who finds salvation through a new religion whose dual god is Dionysus-Christ. Zelazny gives us an adventure about mysticism among dolphins that is unfortunately marred by a thin mystery. The best of the three is Pangborn's gentle story of a new messiah in a post-holocaust world dominated by a repressive church. Less than transcendental.
