This present collection of primary texts reveals the remarkable diversity of the early Christian movement from the time of the New Testament up to the writings of Eusebius (c.100-300). Including works later deemed both "orthodox" and "heterodox", and organized according to historical and social categories (e.g. persecution and marytrdom, the rise of anti-Judaism, the development of church offices, "heresy" and "orthodoxy", and the formation of early liturgy), thetexts are given in clear and up-to-date English translations, each introduced by a concise and informative overview. Packed with clear and compelling information, the collection is suitable for anyone - student, teacher, pastor, layperson - interested in the history and literature of Christianity'sfirst three centuries.
