Confessor and bishop
The title Confessor marks Acacius as one who endured suffering and torture for the faith without being executed. Sources note that, though he was condemned, his steadfastness so impressed the authorities that he was released after considerable suffering rather than martyred. Because he survived his ordeal and reposed in peace, the Church honors him as a Confessor rather than a Martyr.
Beyond his confession, later tradition remembers Acacius as a teacher of the faith and a worker of miracles, esteemed for his doctrinal instruction as well as his endurance.
