This document from the close of the 4th century states: Being as one in their love for Christ, they were also undivided from each other in the army of the world, united not by the way of nature, but in the manner of faith, always singing and saying, “Behold, how good and how pleasant it is for brethren to dwell together in unity!” They were adept and excellent soldiers of Christ, cultivating assiduously the inspired writings to combat diabolical error, and fighting vigorously in battle to defeat the enemy.

There was a lot more in my original post.
