Information about Ancient Christianity is preserved in literary texts. These sources contain passages that became liturgical texts during their history of reception while the context or form of some of them could suggest their ritualized use in the churches of New Testament times. The essays in this volume elaborate on the question of how ancient pieces of liturgy might be found in the extant literature. It also asks how readers of these literary texts can avert the risk of anachronistic reconstructions of ancient liturgies. The topics of this collection range from Jewish Early Medieval poetry to Ancient Greek hymns. The papers discuss the physical appearance of prayer texts among the Dead Sea Scrolls, the performative aspects of texts as they are visible in the Old Testament Suspected Adulteress ritual, as well as prayer texts in the Psalms of Solomon and in the Acts of Thomas. All those lines of research in texts and methods intersect in the conceptual center of the volume: the question of liturgy in the literature of the New Testament which is also debated in detail.
