Worship in the Early Church is a four-volume collection of excerpts from early Christian writings illustrating the Church's liturgical practice in both East and West, from its Jewish beginnings through the end of the sixth century. Source material includes doctrinal and historical treatises, scriptural commentaries, sermons, letters, synod legislation, early church orders, monastic rules, baptismal and funeral epigrams. Each author or major selection is preceded by a short introduction containing such information as dates, country of origin, and various other background details. A bibliography of pertinent periodical and liturgical literature is given as well as a bibliography referencing standard encyclopedias of religion and manuals of patrology. Lawrence J. Johnson is the former executive secretary of the Federation of Diocesan Liturgical Commissions and the former editor/director of The Pastoral Press. He has written several books on the liturgy and its music, including The Mystery of Faith: A Study of the Structural Elements of the Order of the Mass.
