He was noted for his strongly orthodox Christian views. This facilitated the ending of the Acacian schism between the churches of Rome and Constantinople, resulting in good relations between Justin and the papacy. Throughout his reign he stressed the religious nature of his office and passed edicts against various Christian groups seen at the time as non-Orthodox. In foreign affairs he used religion as an instrument of state. He endeavoured to cultivate client states on the borders of the Empire, and avoided any significant warfare until late in his reign.
