We are currently looking at how Christian Church leaders dealt with heresies in the 4th century AD. The most challenging of the heresies was Arianism – the claim that there was a time when the Son of God “was not” and was a creation of God the Father.
Emperor Constantine I called hundreds of bishops together in the city of Nicene to debate this important doctrine. A vast majority of the bishops who attended voted against Arius (namesake of the doctrine of Arianism), excommunicated him and his followers, and wrote a creed known as the “original” Nicene Creed.
That decision in 325 AD did not end the debate or disagreement among leaders in the Church. We detailed some of what happened between the year 325 AD and the Council of Nicea in 325 and the year 381 AD and first Council of Constantinople. You can read that article here.
Before moving to the next stage of the Church’s battle with heresy in the 4th century, let’s take a closer look at what may be the most important aspect of the challenge of Arianism – a challenge still faced today.
