Recently, voices were raised in the worldwide Christian ecumenical movement that it was high time the Protestant-Catholic fundamental topic �Holy Scripture and Tradition� was approached and ecumenically reviewed. In Germany, this has already been achieved by the ��kumenischer Arbeitskreis evangelischer und katholischer Theologen� (Ecumenical Study Group of Protestant and Catholic Theologians; founded in 1946). The results of this study group were published in the 1990s under the title �Verbindliches Zeugnis� by Theodor Schneider and Wolfhart Pannenberg. This edition provides the essence of the three volume work for the first time in English. The treatment of this age-long dispute in Protestant and Catholic theology, but first of all its fundamental settlement can thus be recognised and discussed in the international ecumenical dialogue.
