Many scholars of the Second Temple period have replaced the concept of canonization by that of canonical process. Study of the Dead Sea Scrolls has been crucial for this new direction. Based on this new evidence taxonomic terms like biblical, nonbiblical or parabiblical seem anachronistic for the period before 70 C.E. The notion of authoritative Scriptures plays an important part in the new paradigm of canonical process, but it has not yet been sufficiently reflected upon and is in need of clarification. Why were some texts more authoritative than others? For whom and in what contexts were texts authoritative? And what are our criteria to determine to what extent a text was authoritative? In short, what do we mean by \"authoritative\"? This volume focuses on specific texts or corpora of texts, and approaches the notion of authoritative Scriptures from sociological, cultural and literary perspectives.
