Christian Orthodoxy
Christian Orthodoxy, also known as Eastern Orthodoxy, is a branch of Christianity that traces its theological and liturgical roots to the early ecumenical councils and the apostolic tradition of the Byzantine Empire. It emphasizes the continuity of Holy Tradition, the sacraments, and the mystical experience of worship, particularly through the Divine Liturgy, which centers on the incarnation and resurrection of Christ. Governed by a conciliar model rather than a single hierarchical authority, the Orthodox Church comprises autocephalous (self‑governing) churches united by shared doctrine, iconography, and a common spiritual heritage. Its teachings stress theosis—becoming partakers of divine nature—as the ultimate goal of the Christian life, fostering a deep sense of communal holiness and reverence for the mystery of God.
