Cyprian: On the Unity of the Church Introduction
Who: Third century bishop of Carthage (in modern Tunisia), and martyr from Africa
What: A letter to encourage the unity of the church against schisms and heresy during massive Roman persecution.
Why: A disturbance had happened in the church because of a priest called Novatian—a schismatic of the third century, and founder of the sect of the Novatians. Cyprian wrote to counter this and argues that there can only be one united Church, and the Novatian breakaway was in fact a false church. He also argues that Novatian himself was also an antipope.1
When: Around 249 - 251 AD
1A false claimant of the Holy See in opposition to a pontiff who was officially elected.
