“I indeed am a sinner, yet I have desired to come unto the most Christian emperor, Justinian; now, however, I have found Diocletian; nevertheless, I fear not your threats... Notwithstanding, that you may know you are unworthy of the Christian faith, bid your bishop [Anthemius] confess the two natures in Christ.” Pope St. Agapetus (†536), Speaking to the Emperor Justinian defending his condemnation of the heretical “bishop” Anthemius  [This correction led to the Emperor Justinian discovering Anthemius’s heresy and subjecting himself to Pope St. Agapetus’s judgment.] (Cited in the Liber Pontificalis, translated into English by Louise Ropes Loomis, Ph.D.)
