Two of the founders of the Taizé community in France, Br Roger and Br Max, were among the official observers of the Second Vatican Council, held between 1962 and 1965. They did not only attend the discussion of the Dogmatic Constitution on Divine Revelation (Dei verbum), but also wrote a book offering their explanation and commentary on every paragraph of this document which, among other things, talked about the relationship between scripture and tradition. As Christians, theologians, and practitioners and promoters of the ecumenical movement who inherited the tradition of the Reformation, the two brothers' commentaries may help us to understand, from a Protestant perspective, the development of the interpretation of the Bible in the Catholic Church, and its implication for the unity of Christians. Almost 30 years later, in 1993, the Pontifical Biblical Commission issued a document entitled "The Interpretation of the Bible in the Church". In this document, we can see how the Catholic Church critically evaluates some modern hermeneutical theories, and especially how it approves the works of the French philosopher, Paul Ricoeur, who was a Protestant himself. In this paper, I look into these two texts in which Catholics and Protestants comment and even accept each other, in order to discuss the possibility of seeing the Bible, 500 years after its being a factor of division among Christians, as one of the directions for Christian unity today.
