Seven Ecumenical Councils

The Seven Ecumenical Councils are historic gatherings of Christian bishops, held from the 4th to 8th centuries, to clarify core beliefs and resolve theological disputes. Each council addressed important issues like the nature of Christ, the Trinity, and the church’s teachings, helping define orthodox doctrine. These councils established key doctrines such as the consubstantiality of the Son with the Father and clarified the use of the Nicene Creed, shaping Christianity’s core beliefs. Their decisions are considered authoritative for many Christian traditions, especially Orthodox, Catholic, and some Protestant groups, serving as foundational moments in the development of Christian theology.
