Subordinationist Christology, the Son is subordinate to the Father, was heavily preached by thinkers such as Origen of Alexander (c. 185 – c. 254), historian Eusebius of Caesarea (c. 263 – 339 CE), Eusebius of Nicomedia (c. 260 – c. 340 CE), and others. However, this was not the universal teaching of the church. When Arius (c. 253 – 336 CE), presbyter of the church of the Baucalis in Alexander, said, "If the Father begat the Son, he that was begotten had a beginning of existence: and from this it is evident, that there was a time when the Son was not. It therefore necessarily follows, that he had his substance from nothing", he drew the attention of the church hierarchy. Bishop Alexander of Alexandria (d. 328) was criticized for his slow reaction against Arius. However, when Alexander intervened, a feud arose between Arius and Alexander. At first, emperor Constantine I (r 306-337) wrote to Alexander and Arius telling them to stop quarrelling over such a trivial matter. However, as each side started to gain powerful support, Constantine I feared a serious problem. The emperor convened a meeting in Nicaea (325) and invited all bishops within Christendom (more than 1800) to attend. It was attended by approximately 250 – 300 bishops, mostly from the east. Supposedly, Constantine I did not care about the outcome, but only wanted to settle the dispute.
There are no proceedings from the meeting. Our only knowledge is from post-meeting writings of attendees. The issue was settled in favor of what is now the known as the Trinity – God the Father, God the Son, God the Holy Spirit, with only three dissenting votes. Further, the council issued the Nicene Creed, a version of which is read in mainline churches today. The role of Constantine I is uncertain and it is typically assumed that he did not influence the outcome. However, after the council meeting, Constantine I exiled Arius and the two bishops who voted with him. Moreover, Eusebius of Nicomedia later said, “I voted with my hand, not with my heart”.
In “Nicaea and Its Legacy”, Lewis Ayres presents a well-researched and very thorough treatment of the Council of Nicaea (325) and its impact on Christendom throughout the fourth century.
Ayers describes the activities of many fourth century Christian fathers on both sides of the Arian Controversy, which actually continued into the fifth century. His discussions recount events from the Council of Nicaea (325) - to St. Basil the Great (330-379), who was considered the “architect” of the Trinitarian victory - to Emperor Theodosius I (r 379-392), who issued the Edictum de Fide Catolica (380), mandating Trinitarian Christianity as the state religion of the Roman Empire.
Ayers assumes a certain knowledge on the part of the reader, such that the reader who is not reasonably familiar with fourth century Christianity might find it a difficult read. He constantly refers to Constantius, rather than Constantius II. He mentions the Council of Antioch (341) as, “ostensibly to dedicate a church built by the Emperor Constantius”, but doesn’t name the church (the Domus Aurea). He presents a rambling description of the various councils and tends to ignore chronological order – e.g. he mentions that Constantius II became sole emperor in 353, while many pages later he discusses Council of Sirmium of 351. Certain of his sentences are long and complex, potentially requiring the reader to re-read them several times for a clear understanding. He overuses phrases such as, “It is important ant to note”. This material might have been presented in far fewer pages if his writing style could have been simplified. The “Epilogue” is reasonably clear and perhaps should have been the “Introduction”.
Nevertheless, the knowledge gleaned from this reading is well worth the workout. I recommend this writing for all who are seriously interested in history and theology. However, I suggest some basic reading first.
