9 The receiving of a mandate from the Vicar of Jesus Christ was to Boniface a mark of the divine assistance. Relying on this he feared no difficulties from men or circumstances; and now with the prospect of happier results he hoped to carry out his long cherished design. He traversed various parts of Germany and Friesland. Wherever there were no traces of Christianity, but all was wild and savage, he generously scattered the Gospel seed, and labored and toiled that it might fructify wherever he found Christian communities utterly abandoned for want of a lawful pastor, or being driven by corrupt and ignorant churchmen far from the path of genuine faith and good life, he became the reformer of public and private morality, prudent and keen, skilful and tireless, stirring up and inciting all to virtue.
