Or term, perhaps? What do people of Greek Orthodox faith call the Sacrament of Penance?
Would the biblical term - metanoia - commonly translated as repentance, be an equivalent, or is there a unique word or phrase?
I've stumble on επανορθώνω (which one website says translates to "do penance")
and
εκκλησιαστική which seems to mean "ecclesiastical penalty"
