The Mysteries

The Orthodox tradition has not historically explained the Mysteries through legal categories of merit or contract. It speaks instead of receiving: receiving Christ, receiving the Spirit, receiving the life of the age to come. Each Mystery has a visible matter (water, oil, bread, the laying on of hands), a form spoken by the Church (the prayers of consecration and invocation), a minister set apart in apostolic succession, and a gift that is God’s alone to give.

The fathers do not draw a sharp line between liturgy and life. What is given in baptism is the same Christ who is approached in the Eucharist, the same Spirit who is called down at chrismation and at the laying on of hands. The Mysteries are one fabric, woven by the Spirit around the Body of Christ which is the Church.

The enumeration of seven Mysteries is not a New Testament list. It emerged slowly, was used in the East and West with some variation, and was given conciliar form in the Orthodox Church through the symbolic books of the seventeenth century, notably the Longer Catechism of St Philaret of Moscow (1830) and the earlier Confession of Dositheus (Synod of Jerusalem, 1672). The realities, however, are present from the apostolic generation, and the most ancient catechetical witnesses describe them already as the heart of Christian initiation and life.

The Orthodox tradition has been less anxious than some others to fix the boundary of what counts as a Mystery. The monastic tonsure carries sacramental character, the great blessing of waters at Theophany has long been called a Mystery in its own right, and the rites of burial and the consecration of churches and altars share in the same sacramental logic. The number seven is a useful catechetical anchor. It is not a fence built around the work of the Spirit.

The most accessible patristic introduction is St Cyril of Jerusalem’s Mystagogical Catecheses (lectures XIX–XXIII), delivered to the newly-baptized at Jerusalem in the fourth century. For a brief theological synthesis, St John of Damascus treats baptism, chrismation, and the Eucharist in Exposition of the Orthodox Faith Book IV. For a catechetical treatment that enumerates the seven and walks through each, the Longer Catechism of St Philaret of Moscow is the standard nineteenth-century Russian witness. For the mystical theology that holds it all together, the Ecclesiastical Hierarchy of Pseudo-Dionysius remains foundational.
