Knowing that he that is such is perverted, and sins, being condemned of himself.
All Commentaries on Titus 3:11 Go To Titus 3
Cyprian of Carthage
AD 258
The church cannot be rent or divided against itself. It maintains the unity of a single, indivisible house…. All who are to live and escape the destruction of the world must be gathered into one house alone, the church. If any of the gathered goes outside, that is, if anyone who once obtained grace in the church nevertheless abandons the church, his blood will be upon his head. He will have himself to blame for his damnation. The apostle Paul explains this, directing us to avoid a heretic as perverted, sinful and selfcondemned.
