According to Margaret Barker's groundbreaking theory, temple mysticism underpins much of the Bible. Rooted in the cult of the first temple in ancient Judaism, it helps us to understand the origins of Christianity. Temple mysticism was received and taught as oral tradition, and many texts were changed or suppressed or kept from public access. Barker first examines biblical texts: Isaiah, the prophet whom Jesus quoted more than any other in Scripture, and John. Then she proposes a more detailed picture, drawing on a wide variety of non-biblical texts. The resulting book presents some remarkable results.

Mysticism in Early Modern England traces how mysticism featured in polemical and religious discourse in seventeenth-century England and explores how it came to be viewed as a source of sectarianism, radicalism, and, most significantly, religious enthusiasm.

Starting from a careful definition of mysticism, this volume argues that there is clear evidence for the practice of mysticism in the Community of the Dead Sea Scrolls. It offers a close reading of the Songs of the Sabbath Sacrifice, the Self-Glorification Hymn, and related texts, which constitute the Qumran mystical corpus. It discusses the nature of the mystical experience at Qumran, which was centred on union with the angels in offering praise to God in the celestial temple, and the means by which this union was achieved, through the communal chanting of highly-charged numinous hymns. It also argues that that the presence of mysticism at Qumran has important implications for the history of western mysticism. It means that Jewish mysticism began in priestly circles in Second Temple times, several centuries before the commonly accepted date. And the important form of Christian mysticism involving speculation on the angelic hierarchies, classically associated with Dionysius the Areopagite, had a pre-Christian Jewish forebear. Consequently Qumran mysticism belongs to the genealogy of Christian as well as of Jewish mysticism. This volume synthesizes and makes accessible a mass of technical research widely scattered in monographs and articles, and offers the reader a clear guide to the most recent scholarly work in the field.

For a long time scholarship has been seeking the origins of Christian worship in the synagogue. In this new major book, Margaret Barker traces the roots of Christian worship back to the Jewish temple. By proposing a temple setting, a great deal more can be explained, and the existing rather limited resources can be more fruitfully used. By working with a great variety of sources (canonical, extra-canonical and Fathers, all presented here in translation), it is possible to reconstruct something of the early Christian world view, which shows the Church as the conscious continuation of the temple worship. Fundamental practices such as baptism and the Eucharist had Temple Roots, and familiar words in the liturgy of the church such as Maranatha and Hallelujah derived from the ancient belief that the Lord appeared in the Temple. Jesus was the God of Israel manifested as a the Great High Priest, and the Christians were his new angel priesthood, singing the angelic liturgy to restore and renew the earth. The chapters in this book cover baptism, in theology and practice, the Eucharist, with special emphasis on the symbolism of the elements, the significance of music and hymns, festivals and pilgrimage, use of the Scriptures, both what the early Christians used and how they read them, prayers, including the Lord's prayer, and the shape of church buildings.

Margaret Barker believes that Christianity developed so quickly because it was a return to far older faith—far older than the Greek culture that is long-held to have influenced Christianity. Temple Theology explains that the preaching of the gospel and the early Christian faith grew out of the centuries' old Hebrew longing for God's original Temple.

'The Origins of Jewish Mysticism' offers an in-depth look at the history of Jewish mysticism from the book of Ezekiel to the Merkavah mysticism of late antiquity. The author reveals what these writings seek to tell us about the age-old human desire to get close to and communicate with God.
