Early Christianity:
A Brief Overview of the Ante-Nicene Era

The Council of Nicea in A.D. 325 is a natural time to end "early Christianity," the post-apostolic period. Almost every history book will refer to the period from A.D. 100, which is about the time of John the apostle's death, to A.D. 325 as the "Pre-Nicene" or "Ante-Nicene" era.

Nicea serves as a dividing line because the emperor Constantine, though never becoming a Christian until his deathbed, greatly favored Christianity during his reign. As a result, the number of Christians increased from about 10% of the empire to about 90%.

Most of these converts were simply following the emperor, not submitting themselves to Jesus. The effect on early Christianity was dramatic.

But the description of the dramatic change must wait for the next section. Here we are concerned with the era before Nicea.

Unity and Apostolic Truth in the Early Christianity

If I have to pick the outstanding feature of this era, then I choose the independence of the churches. People like to say that a hierarchy began to form before Nicea. It began in the 3rd century, but not in the 2nd.

The ante-Nicene churches were simple and free. They found their unity in wholehearted devotion to Christ, not in a systematic theology or set of doctrines.

A more complete description of these things along with numerous other quotes from the period can be found in the Pre-Nicene era section.

Holiness in the Early Churches

The other notable thing about this era was the holiness of the early churches. Christians were still subject to intermittent persecution in the early Christianity. As a result, those who chose to follow Christ were those willing to commit everything to the kingdom of God. It could cost them their lives!

Martyrdom of Ignatius of Antioch

Holiness and perseverance lessened as the 3rd century wore on; however, the remarkable lives of Christians during the 2nd century—their deep love for one another and their endurance during persecution—were powerful testimonies to the Romans around them.

By the 3rd century, Christianity was becoming popular.

The result was that there were Christians who were not so separated from the world as others before them. Tracts can be found calling Christians to separate from Roman entertainment and other worldly pursuits.

Christians that fell away during persecution but later wanted readmittance to the Church also became a problem, and it led to numerous debates and a large split in the mid-3rd century, led by a Roman elder named Novatian.

Evangelism in Early Christianity

It is worth noting that unlike the apostolic era, Ante-Nicene Christianity had no famous evangelists or apostles. When Justin Martyr describes those converted to Christianity in the mid-2nd century, he says it was caused by:

• The consistency they witnessed in their neighbors' lives,
• the extraordinary forbearance they saw in fellow travelers when defrauded,
• and the honesty of those with whom they conducted business. (First Apology 16)

Tertullian says that new churches were being raised up every day in early Christianity, and he, too, attributes it to the lives of Christians, saying, "The oftener you mow us down, the more of us there are. The blood of Christians is seed" (Apology 50).
