“Wherefore also in the Gospel it is written: “if I have wronged any man of any thing, I restore him fourfold.” (Lk. 19)... And it is read in Divine Law: “Cursed is everyone who moves over his neighbour’s landmarks: and all the people shall say: Amen.” (Dt. 27) 　Such things therefore may not be presumed without vengeance, nor exercised without one’s own damnation.” Pope St. John I, Epistle to Archbishop Zachary, “De non accusandis episcopis”, 523 A.D
