PHILIP MORRISON and PHYLIS MORRISON
[In "The Christmas Sky", the] Star of Bethlehem is … sought by reason. Page by page in this clear and gentle book the possibilities are explored. It was not a meteor, because it endured; it was not a comet, because it was welcome; it was not a nova. The birth of Jesus is carefully and convincingly dated from the circumstances of history.
