The Mission to Constantinople
Italy in the 530s lay under Ostrogothic rule, and as relations between the Gothic kingdom and the Eastern Empire deteriorated, the Gothic king dispatched Agapitus to Constantinople to negotiate peace and to dissuade the Emperor Justinian from a military campaign in Italy. According to Western sources, the pope set out in mid-winter 535 in the company of several bishops and arrived in the capital early in 536. The emperor, however, declined to abandon his preparations.
Once at Constantinople, Agapitus turned to the affairs of the Church. He found the patriarchal throne occupied by Anthimus, whom he regarded as having intruded improperly upon the see and as suspect in faith. When Anthimus would neither give a written profession of Orthodox belief nor return to his former see, Agapitus deposed him and, by the Western account, personally consecrated Menas as patriarch in his place. He further upheld Orthodox Christology against the teaching associated with Severus, which held that the body of Christ was subject to corruption as that of any man.
