Saint Boniface preached the Gospel to the people and used a little fir tree as a tool of evangelization.
Pointing to that tree he said,
“This little tree, a young child of the forest, shall be your holy tree tonight. It is the wood of peace… It is the sign of an endless life, for its leaves are ever green. See how it points upward to heaven. Let this be called the tree of the Christ-child; gather about it, not in the wild wood, but in your own homes; there it will shelter no deeds of blood, but loving gifts and rites of kindness."
