Whilst thus making use, at the expense of the Church, and for political interests, of material force, Charles Martel was far from misunderstanding her moral influence and the need he had of her support at the very time when he was incurring her anathemas. Not content with defending Christianity against Islamism, he aided it against Paganism by lending the Christian missionaries in Germany and the north-west of Europe, amongst others St. Willibrod and St. Boniface, the most effectual assistance. In 724, he addressed to all religious and political authorities that could be reached by his influence, not only to the bishops, “but to the dukes, counts, their vicars, our palatines, all our agents, our envoys, and our friends this circular letter: ’Know that a successor of the Apostles, our father in Christ, Boniface, bishop, hath come unto us saying that we ought to take him under our safeguard and protection. We do you to wit that we do so very willingly. Wherefore we have thought proper to give him confirmation thereof under our own hand, in order that, whithersoever he may go, he may there be in peace and safety in the name of our affection and under our safeguard; in such sort that he may be able everywhere to render, do, and receive justice. And if he come to find himself in any pass or necessity which cannot be determined by law, that he may remain in peace and safety until he be come into our presence, he and all who shall have hope in him or dependence on him. That none may dare to be contrary-minded towards him or do him damage; and that he may rest at all times in tranquillity and safety under our safeguard and protection. And in order that this may be regarded as certified, we have subscribed these letters with our own hand and sealed them with our ring.’”
