Henry and Poppo were both of them relatives of Otho, who in 956 caused the former to be raised to the archbishopric of Treves. Henry insisted on carrying his friend with him into his new diocese, and wished to load him with benefices and honours, all of which, however, Wolfgang refused. He would accept of no other employment than that of teaching youth, for which he knew his aptitude, and which he heartily loved; and, in the true spirit of a Christian teacher, he chose to discharge this office gratuitously, not as a means of private gain, but as a work for souls, even supporting many of his scholars out of his own purse. He cared as much for their spiritual as their intellectual progress, and set them the example of a holy and mortified life. The archbishop, in despair at not being able to promote him as he desired, at last got him to accept the office of dean to a certain college of canons. Wolfgang did not allow the dignity to be a nominal one, but obliged his canons to embrace community life, and to commence a course of sacred studies, assuring them that the sustenance of the inner man is as necessary as that of the body. Archbishop Henry dying in 964, Wolfgang, who had only remained at Treves out of affection to him, prepared to return into Swabia, which was his native country. But Bruno had his eye on him, and inviting him to Cologne, offered him every dignity, even the episcopate itself, if he would only remain in his duchy. Wolfgang, though he persisted in refusing to accept any promotion, felt himself obliged to pass some time at the prince-bishop’s court, and testified afterwards to the fact of his great sanctity. Finding that he could not move the resolution of his friend, Bruno at last reluctantly allowed him to return to Swabia, where he remained only just long enough formally to renounce his hereditary possessions, after which he withdrew to Einsidlen, and took the monastic habit under the English abbot Gregory.
