CH101 - The Fourth Century
The Church Established, 303 - 400 A.D.
Constantine Comes to Power
While the persecution was being carried out in the East where the numbers of Christians were much greater, the Western Christians experienced very little pressure. Under Constantius (the father of Constantine) some church buildings were destroyed in Britain, Gaul, and Spain - that was the extent of persecution - there is no evidence that any Christian was executed. In addition to this lack of brutality, Constantine's half sister was named Anastasia (anastasis - Greek for "resurrection"). This indicates a Christian influence in the household of Constantius.
The details are far more complicated with the empire being led by an Augustus ruler with a Caesar under him in the East and in the West. In addition, there were several struggles (like civil war) for control. A simple overview:
When Constantius died in 306 his military proclaimed his son Constantine to be the new emperor in the West.
306 - Constantius died, his son Constantine replaces him
310 - Maximian rebels against Constantine and fails
311 - Galerius died, Maximin Daia replaces him in the East
311 - Maximin and Licinius fight for control in the East
311 - Constantine and Licinius form alliance
In 312 Constantine engaged Maxentius (son of Maximian) for sole rulership in the West at the famous "Battle of the Milvian Bridge." According to Lactantius (the date given later by Eusebius indicates an earlier battle) Constantine had a vision of a cross in the sky and heard a voice saying something like, "Go, and in this symbol, conquer." In the battle Maxentius drowns in the Tiber river attempting to retreat. Though the details are sketchy and not easy to fully reconcile, it appears that Constantine knew enough of Christianity to believe that his vision was of the God of the Christians, that he was chosen (or destined) by this God to rule the empire, and it was the beginning of his embrace of Christian faith. We will discuss the faith of Constantine in more detail later.
This battle leaves Constantine as the sole leader of the empire in the West.
313 - Constantine and Licinius sign the Treaty of Milan
This treaty marks an historic moment for the Christian faith. It is decreed that all Roman citizens would have religious freedom - the ability to worship however they wanted without interference from the empire. This did NOT represent Constantine making Christianity the official religion, but it does effectively put an end to the persecution of Christians.
Constantine and Licinius also entered something of a truce, putting an end to the leadership strife that had existed for the previous 20-25 years. This truce lasted until 324 AD when Constantine became the sole ruler of the Roman empire.
