Nicaea 2025

Created on: 26 November 2024

What is the anniversary of Nicaea 2025? 

In 2025, we mark the 1700th anniversary of the world’s first Ecumenical Council. The Council of Nicaea, held in 325AD, brought together 318 bishops to affirm the Apostolic Faith and the Church’s belief in the triune God, as proclaimed in the Nicean Creed. 


Why is the Council of Nicaea important? 

The Council of Nicaea in 325AD was the first ecumenical council of the Christian Church and is widely regarded as one of the most important events in Christian history. The event, requested by St. Constantine the Great, played a critical role in overcoming the heresy of the Arianism and shaping the theological foundation and unity of Christianity.
