2 In these dark times, the memory of St. Boniface, who brought salvation to Germany twelve centuries ago, is a ray of light and a messenger of hope and joy. We commemorate the ancient union of the German people with the Apostolic See. This union planted the first seeds of faith in your country and helped them grow. After the Roman See entrusted Boniface with this legation, he ennobled it by the exceptional glory of his deeds and, finally, by the blood of martyrdom.
