In 1969, he returned to Bavaria, to the University of Regensburg and co-founded the theological journal "Communio", with Hans Urs von Balthasar, Henri de Lubac, Walter Kasper and others, in 1972. "Communio", now published in seventeen languages, including German, English and Spanish, has become a prominent journal of contemporary Catholic theological thought. Until his election as pope, he remained one of the journal's most prolific contributors. In 1976, he suggested that the Augsburg Confession might possibly be recognised as a Catholic statement of faith. Several of Benedict's former students became his confidantes, notably Christoph Schönborn, and a number of his former students sometimes meet for discussions. He served as Vice President of the University of Regensburg from 1976 to 1977.
