Dcn. Seraphim opens the series by arguing that Orthodoxy is fundamentally a life to be lived — in the nave, at the icon corner, at weddings and deathbeds — rather than a body of information consumed on a screen. Drawing on the tradition of the martyrs and the Celtic threefold martyrdom (red, green, and white), he frames the goal of catechesis as the making of witnesses to Christ in whatever state of life God has placed them. He closes by previewing the shape of the series: praxis first (prayer, fasting, almsgiving), then moral life, the Holy Mysteries, and finally dogmatics.
