Synods of Antioch

Beginning with three synods convened between 264 and 269 in the matter of Paul of Samosata, more than thirty councils were held in Antioch in ancient times. Most of these dealt with phases of the Arian and of the Christological controversies.^[1] For example, the Catholic Encyclopedia article on Paul of Samosata states:

It must be regarded as certain that the council which condemned Paul rejected the term homoousios; but naturally only in a false sense used by Paul; not, it seems because he meant by it a unity of Hypostasis in the Trinity (so St. Hilary), but because he intended by it a common substance out of which both Father and Son proceeded, or which it divided between them, — so St. Basil and St. Athanasius; but the question is not clear. The objectors to the Nicene doctrine in the fourth century made copious use of this disapproval of the Nicene word by a famous council.^[2]

The most celebrated convened in the summer of 341 at the dedication of the Domus Aurea, and is therefore called in encaeniis or dedication council. Nearly a hundred Eastern bishops were present, but the bishop of Rome was not represented. The emperor Constantius II attended in person.^[1]
