Pope John Paul II introduced the Christmas tree custom to the Vatican in 1982. Although at first disapproved of by some as out of place at the centre of the Roman Catholic Church, the Vatican Christmas Tree has become an integral part of the Vatican Christmas celebrations, and in 2005 Pope Benedict XVI spoke of it as part of the normal Christmas decorations in Catholic homes. In 2004, Pope John Paul called the Christmas tree a symbol of Christ. This very ancient custom, he said, exalts the value of life, as in winter what is evergreen becomes a sign of undying life, and it reminds Christians of the "tree of life" of , an image of Christ, the supreme gift of God to humanity. In the previous year he said: "Beside the crib, the Christmas tree, with its twinkling lights, reminds us that with the birth of Jesus the tree of life has blossomed anew in the desert of humanity. The crib and the tree: precious symbols, which hand down in time the true meaning of Christmas." The Catholic Church's official "Book of Blessings" has a service for the blessing of the Christmas tree in a home. The Episcopal Church in "The Anglican Family Prayer Book", which has the imprimatur of The Rt. Rev. Catherine S. Roskam of the Anglican Communion, has long had a ritual titled "Blessing of a Christmas Tree", as well as "Blessing of a Crèche", for use in the church and the home.
