The Macarian writings are among the most important and influential works of the early Christian ascetic and mystical tradition. This book offers an introduction to the work of Macarius-Symeon (commonly referred to as Pseudo-Macarius), outlining the lineaments of his teaching and the historical context of his works. The book goes on to examine and re-evaluate the complex question of his relationship with the Messalian tendency and to explore the nature of his theological and spiritual legacy in the later Christian tradition. In so doing the book also offers substantial treatments of the work of Mark the Monk, Diadochus of Photice, Abba Isaiah, and Maximus Confessor. It stands therefore not only as an exploration of the teaching and legacy of Macarius-Symeon but also as a chapter in the history of the Christian spiritual tradition.

Given the degree of popular fascination with Gnostic religions, it is surprising how few pay attention to the one such religion that has survived from antiquity until the present day: Mandaism. Mandaeans, who esteem John the Baptist as the most famous adherent to their religion, have in our time found themselves driven from their historic homelands by war and oppression. Today, they are a community in crisis, but they provide us with unparalleled access to a library of ancient Gnostic scriptures, as part of the living tradition that has sustained them across the centuries. Gnostic texts such as these have caught popular interest in recent times, as traditional assumptions about the original forms and cultural contexts of related religious traditions, such as Judaism, Christianity, and Islam, have been called into question. However, we can learn only so much from texts in isolation from their own contexts. Mandaean literature uniquely allows us not only to increase our knowledge about Gnosticism, and by extension all these other religions, but also to observe the relationship between Gnostic texts, rituals, beliefs, and living practices, both historically and in the present day.
