A VERY short excursion in the field of comparative religions will show how one idea seems to have come from the far East in the early days of mankind, and to have taken root in the minds of all races who came westward. We have already referred to the faith which led the Magi to follow the star to Bethlehem. Throughout the East it was the primæval instinct that a child was to be born of a celestial mother, who should destroy the spirit of evil and be the saviour of mankind.
