Non-Violence in the Early Church
For those who are unconvinced by the consistent, recurrent testimony of Scripture, and the plain example and practice of Christ and the Apostles on the subject of Christian Non-Violence, I present the exhaustive list of quotations from the early Church in the first 400 years. Featuring quotes from hearers of the Apostle John and hearers of theirs.

The hard headedness on so many regarding this topic confounds me. Why is the Church not willing to take seriously Jesus teaching.

I’m encouraged in seeing recent works by guys like Preston Sprinkle.
