John Paul II introducing the tradition of the Christmas tree in St. Peter’s Square emphasized that it is a symbol of the tree of life, the one mentioned in the Book of Genesis, and because it is decorated with lamps, it is a symbol of life and light. The Christmas tree unites people regardless of age. The appearance of the Christmas tree in St. Peter's Square and the Holy Father's palace in the Vatican caused an avalanche reaction. Beautiful Christmas trees appeared in many Italian homes, and Christmas trees replaced other Christmas decorations on the streets and city squares.
