On October 12, 1960, a group of German and Swiss Moravians met with Karl Barth to discuss Zinzendorf's theology. The meeting took place in the building of the Moravian society in Basel, Switzerland. Participants also included several of Barth's doctoral students. Having abandoned his earlier critical reading of Zinzendorf, Barth had become more appreciative of Zinzendorf's Christocentrism in his later years. The report of the conversation was published in German and in English in journals of the Moravian Church in 1961. In order to make the text better accessible in preparation for the sixtieth anniversary of the conversation, the English translation is published here.
