Companion in the Monothelite Struggle
The conflict in which Anastasius suffered concerned Monothelitism, the seventh-century teaching that Christ possessed only a single, divine will. Saint Maximus the Confessor became the foremost defender of the doctrine that Christ possesses two wills, human and divine, corresponding to his two natures. As Maximus's disciple, Anastasius stood with him through trial, condemnation, and the punishments that followed.
The synaxarion describes the company being exiled to Skemarum in Scythia, enduring many sufferings and difficulties on the journey. The mutilation of the tongue and right hand—the same penalty borne by Saint Maximus—was meant to end the confessors' ability to proclaim or record their faith, yet the tradition holds that Anastasius continued to bear witness through the written Life of his teacher.
