The essays in this volume summarize an international research project on early Christian citations from Israel's scriptures. These quotations are not only theologically significant but are also part of the textual history of the Septuagint and adjacent textual traditions of the Greek and Hebrew Old Testament. The essays discuss relevant manuscripts (Bible codices, papyri, etc.) up to the fifth century, signs and marginal notes (e.g., the diplé) that were used in the ancient scriptoria, and the specifics of the reception history in early Christianity from Matthew to 1 Peter and from the apostolic fathers to Theophilos of Antioch. The contributors are Felix Albrecht, Ronald H. van der Bergh, Heinz-Josef Fabry, Kerstin Heider, Martin Karrer, Christin Klein, Arie van der Kooij, Siegfried Kreuzer, Horacio E. Lona, Martin Meiser, Maarten J. J. Menken, Matthias Millard, Darius Müller, Ferdinand R. Prostmeier, Alexander Stokowski, Martin Vahrenhorst, Christiane Veldboer, and Johannes de Vries.
