Very simply the stranger told the people the story of Jesus and the Cross, and before the tale was ended the hammer had fallen from the hand of the high priest, had fallen harmless to the ground. The little child was saved
Then seizing the hammer, St. Boniface himself felled the sacred oak, and even as he did so, his eyes fell upon a young fir tree, standing straight and green before him.
"Here is the living tree," he cried, "with no stain of blood upon it, which shall be the sign of your new worship. See it pointing to the sky! Let us call it the tree of the Christ Child. Take it up and carry it to the hall of your chief, for this is the birth-night of the White Christ. You shall no more keep your feasts in the shades of the forest with secret and cruel rites. You shall keep them in your own homes, with happy laughter and glad songs of glee."
