[2] Agapetus arrived in Constantinople in February or March 536 on a diplomatic mission for the Ostrogothic king Theodahad.
While this was true—he had transferred from the diocese of Trebizond—the real reason for the pope's refusal was probably his suspicions of the patriarch's theology.
Lacking support from the emperor, who had called for a council to meet in Constantinople in May, Anthimus resigned.
[1][3] Shortly after, Justinian issued an order (keleusis) to the new patriarch to convoke a synod to investigate Anthimus.
[4] It is probable that the removal of Anthimus had been planned for some time since the participation of Palestinian monks in the synod would only have been possible had they been apprised of the council before the arrival of the pope in Constantinople.
[1] The assembled clergy, monks and bishops issued a series of condemnations of the teachings of Anthimus, Severus, Peter of Apamea and Zooras of Amida.
[8] In response to the council, on August 6 Justinian issued an imperial rescript (diataxis) declaring Anthimus, Severus, Peter and Zooras to be heretics and prohibiting them from living in Constantinople.
