History
St. Johannes-Bruderschaft's predecessor "Evangelisch-Katholische Eucharistische Gemeinschaft" (Evangelical Catholic Eucharistic Society)
was founded 1929 in Germany. It was forbidden 1937 in Nazi Germany because of its resistance to Aryan paragraphs and Internationalism, but was founded again in 1947 as "Evangelische-Ökumenische St.-Johannes-Bruderschaft".
The first Apostolischer Vorsteher of the confraternity was Friedrich Heiler (1929-1967). He arranged to receive the episcopal consecration from a bishop of the independent Gallican Church (Petite L'Eglise) in Syrian-orthodox tradition. On August 25, 1930, Heiler received from the hands of the Gallican Bishop Petrus Gaston Vigué, using the Roman Ritual, all the Holy Orders including the episcopate.
