What Are The 21 Ecumenical Councils?
Throughout church history, there were 21 distinct meetings that were made to settle disputes, sending large amounts of Christians to discuss. Some councils are very controversial while others are confirmed by all Christians(with or without knowledge). Here we will discuss all 21 of the ecumenical councils.
First Council of Nicaea:
In 325, the First Council of Nicaea is the first ecumenical council. This council was called in a city called Niceae where it gets its name. In today's world, it is the city of İznik, Turkey. This council was called by Constantine the First who hoped to settle down the dispute over the Trinity. If it was indeed biblical or not. One side, the Arians, practiced a doctrine known as Arianism. It gets its name from Arius of Alexandria, the man who invented it. In this doctrine, Jesus is a created being. During this council, the Trinity was affirmed and the word homoousios was used. This term homoousios means of one substance, so Jesus is of the same, or one substance as the Father and Spirit. Is the Nicene Creed Biblical? (Read Here)
First Council of Constantinople:
In 381, the First Council of Constantinople is the second ecumenical council. This council was called by the emperor Theodosius I(the first) where they met in Istanbul or Constantinople.
In the council, they confirmed Trinitarianism, specifically concerning the equality of the three persons of God(The Holy Spirit, Jesus(or The Son), and The Father).
The Second Council of Ephesus:
There were actually three councils in Ephesus; however, the second council of Ephesus is the only council that is considered ecumenical. In 431, Pope Celestine I(or the First) conducted a council against Nestorius. Nestorius taught a doctrine known as Nestorianism which teaches that Christ is two different persons, a divine and human(or flesh). The conclusion of the council is that Nestorianism is heretical and the Pope excommunicated Nestorius.
Council of Chalcedon:
In 451, emperor Marcian called this council which was held in Chalcedon(modern-day Kadiköy, Turkey). This creed approved the Nicene and Constample creeds. It too recondemned Nestorianism and monophysitism, then confirming the hypostatic union.
Second Council of Constantinople:
In 553, the fifth ecumenical council was called. This council condemned Nestorianism and ratified a condemnation against Origen, this was likely over his view that the Devil could accept Christ if he repented.
Third Council of Constantinople:
From 680-681, the sixth ecumenical council was called by emperor Constantine IV(or the fourth). In this council, Monothelites(the idea that Jesus only had one will) was condemned while Dyotheletism was affirmed(the idea that Jesus had a human-divine will).
Second Council of Nicaea:
Established guidelines for the veneration of images. (Some Protestants reject this council, while accepting the Council of Hieria of 754, which rejected the veneration of icons.)
