C. E. Hammond's Antient Liturgies provided a valuable resource at an early stage in comparative liturgical studies. Free of extensive critical apparatus, Antient Liturgies presents a collection of historic forms of worship from the Western, Eastern, and Oriental Churches. This extract from the book focuses on the Clementine Liturgy, an important early liturgy, apparently known even to Justin Martyr. Rendered in Greek and with an analytical introduction this early study continues to provide a broad overview of early Christian worship made available in an accessible and convenient format for students and scholars.
