This volume contains the Proceedings of the 50th Colloquium Biblicum Lovaniense: the 40 contributions, written in English, French and German, focus on the canons of the Old and New Testament as well as those of the Bible as a whole. The theme is studied from a variety of historical, hermeneutical and biblical-theological points of view. Several contributions discuss the process that resulted in the canonical status of certain writings, or groups of writings, in particular, such as the Book of Psalms, Ezekiel, the Wisdom of Ben Sira, the Pauline corpus, Acts and the gospels.
