The compromise of serving two masters (e.g. the synthesis of church and state) results in, among other things, the belief that it's acceptable to kill others - believers
or unbelievers. The false dichotomy is similar to the two cites posted here, where one is based in faith and the other is based in man -->
The New Testament -> for Jesus, Paul, the apostles, and the followers of Jesus in the 1st century.
The Ante Nicene Church Fathers -> for the followers of Jesus in the 2nd and 3rd centuries.
Witness the attempts to pigeonhole the question, to force an answer from among believers, while avoiding the whole truth of the matter.
But the Jews which believed not, moved with envy, took unto them certain lewd fellows of the baser sort, and gathered a company, and set all the city on an uproar, and assaulted the house of Jason, and sought to bring them out to the people. And when they found them not, they drew Jason and certain brethren unto the rulers of the city, crying, These that have turned the world upside down are come hither also; Whom Jason hath received: and these all do contrary to the decrees of Caesar, saying that there is another king, one Jesus. And they troubled the people and the rulers of the city, when they heard these things.
