Any history of Christian liturgy must address the origins and development of the various material elements that are used during these celebrations. These have their own specific history, just as does the architectural and artistic context of the liturgy. Many of the specialized garments, or vestments, worn by ministers during liturgical services in several contemporary Christian churches originated in elements of ordinary or honorific dress used in the ancient Roman Empire. Over the course of several centuries, the style and type of vestments used in Western Christianity diverged from those used in Eastern Christianity, until today the differences are more striking than the similarities, even in shared individual elements like the stole and the chasuble. In addition, different kinds of vestments are used by different ministers (for example, the deacon, priest, or bishop) and in different kinds of sacramental and liturgical ceremonies. What a minister might wear at one service, for example evening prayer or the administration of baptism, might not be the same as those expected for the celebration of the Eucharist (the Mass, the holy communion, or the divine liturgy). The same is true for the essential vessels used during the celebration of the Eucharist: the chalice to hold the wine, and the paten, or plate, on which rests the bread to be blessed. Both of these have developed in distinctive styles in both West and East over time. The same is true of many of the other vessels and implements needed for the Eucharist and those used in other liturgical services. Examples include containers designed to hold water, oil, or incense as well as the number and style of altar cloths, veils, and candles utilized at different times and places.

The Christian word “priest,” which is generally used to translate the Greek word hiereus and the Latin word sacerdos, only inadequately captures the essence of how those who bore this title functioned and were perceived in Greek and Roman polytheism. Foremost among the differences between pagan and Christian priests is the fact that the former did not have any pastoral responsibilities, were not expected to lead exemplary lives, and did not exist in a hierarchy under a centralized religious authority. Instead their duties were largely liturgical and administrative, the proper performing of sacrifice and the upkeep of the sanctuary being among the foremost. Methods of appointment varied—some priesthoods were reserved within specific kin-groups, others were available to the entire citizen body, and still others could be sold to the highest bidder. There were, however, important distinctions between Greek and Roman priests. In the Roman world, for instance, there were far fewer priestesses and a closer connection between religion and politics. In both systems, however, religion provided important outlets for women, not least by presenting them with a unique opportunity to enhance their social status. In Rome the connection between religion and politics strengthened over time. Under the Augustan Principate the position of pontifex maximus, a kind of high priest, became central to the identity of the princeps and was filled by all his successors at least until the late-4th century. The Graeco-Roman world also had a variety of other religious personnel, who performed important functions like the supervising of temple finances or the expounding of sacral law. Among the most important were seers or diviners, who produced oracles and had the expertise to interpret omens.
Biblical laws are found mainly in the Pentateuch (i.e., the first five books of the Hebrew Bible). The laws are linked to the figure of Moses, who is depicted as having received them directly from God in order to transmit them to the people of Israel during the years in the Wilderness after being released from slavery in Egypt. Biblical laws are thus presented as being of divine origin. Their authority was further bolstered by a tradition that they were included in covenants (i.e., formal agreements made between God and the people as recorded in the books of Exodus and Deuteronomy). Similar claims of divine origin were not made for other ancient Near Eastern laws; their authority flowed from kings, who issued the laws, although these kings might also be seen as having been placed on their thrones through the favor of the gods. The biblical law collections are unlike other ancient Near Eastern “codes” in that they include sacral laws (i.e., governing cult, worship, and ritual, as well as secular laws: namely, governing civil, and criminal behaviors). This mingling of sacral and secular categories is the likely reason both for the many terms used to denote the laws, as well as for the unexpected number of formulations in which they are presented. The formulations used in biblical law can be classified as “casuistic” or “non-casuistic.” They are not equally distributed in the books of the Pentateuch nor are they equally used with secular and sacral laws. While there are similarities in content between secular laws found in the Hebrew Bible and laws found in the ancient Near Eastern law “codes,” the latter do not exhibit a comparable variety in the numbers of law terms and formulations. The Hebrew Bible tended to “blur” the differences between the law terms and their formulations, ultimately to the point of subsuming them all under the law term torah (“teaching”) to describe the totality of the divinely given laws in the Pentateuch. Biblical studies in general and Pentateuchal studies in particular are challenged by the fact that manuscripts contemporary with the events described have not survived the ravages the time. Scholars must therefore rely on looking for “clues” within the texts themselves (e.g., the laws cited by the prophets, the reform of Josiah, the teaching of torah by Ezra, and evidence for customs and customary laws found in books of the Hebrew Bible outside of the Pentateuch).
