What does it mean to confess that the Orthodox Church is the one, holy, catholic, and apostolic Church, and how should we understand Christians who live outside her canonical boundaries? Fr. Harry and Fr. Anthony explore the distinction between heresy and schism, the wisdom of St. Basil's canons, and the Church's historical practices of reconciliation, challenging the assumption that ecumenical dialogue necessarily compromises Orthodox faith. Along the way, they consider the mystery of God's grace, the dangers of reducing ecclesiology to rigid formulas and giving away the farm, and the responsibility of Orthodox Christians to pursue unity with humility, discernment, and love.
