THE DOGMATIC, PATRISTIC AND LITURGICAL VALUE OF THE FIRST ECUMENICAL COUNCIL OF NICAEA (325 AD): THE FOUNDATION OF ORTHODOXY IN THE FACE OF THE ARIAN HERESY

Summary/Abstract: The First Ecumenical Council of Nicaea (325 AD) represents a fundamental turning point in the history of the Orthodox Church, providing a clear dogmatic response to the Arian heresy. By adopting the term homoousios ("of one being with"), the Church affirmed the consubstantiality of the Son with the Father, thus establishing the Trinitarian foundation of Orthodox faith.The article analyzes the historical and theological context of the synod, the contributions of the Church Fathers in the reception and deepening of the synodal decisions, as well as the integration of dogma into liturgical life, hymnography and iconography. The work also assesses the relevance of the Nicene message in the face of contemporary challenges:theological relativism, secularization, religious pluralism and ecumenical dialogue.The Council of Nicaea proves to be not only a historical event, but a living,canonical and saving norm, reaffirmed in worship, dogma and ecclesial experience.Fidelity to this confession remains essential for any authentic theological dialogue and for the preservation of Orthodox identity.
