16 Through the activity of St. Boniface, what was certainly a new era dawned for the German people; new not only for the Christian religion, but also for Christian civilization. Consequently this nation should rightly consider and regard him as their father, to whom they should be ever grateful and whose outstanding virtues they should zealously imitate. "For it is not only almighty God Who is called Father in the spiritual order, but also all those whose teaching and example lead us to the truth and encourage us to be strong in our religion. . . Thus the holy bishop Boniface can be called the father of all Germans, since he was the first to bring them forth in Christ by his holy preaching and to strengthen them by the example of his virtue, then finally to lay down his life for them, greater love than which no man can show."
