Saying, Let us alone; what have we to do with you, Jesus of Nazareth? are you come to destroy us? I know you, who you are, the Holy One of God.
All Commentaries on Mark 1:24 Go To Mark 1
Irenaeus of Lyons
AD 202
Even the demons cried out, on beholding the Son: “I know who you are, the Holy One of God.” Later the devil looking at him and tempting him, would say: “If you are the Son of God.” All of these thus recognized the Son and the Father, yet without believing. So it was fitting that the truth should receive testimony from all, and should become a means of judgment for the salvation not only of those who believe, but also for the condemnation of those who do not believe. The result is that all should be fairly judged, and that the faith in the Father and Son should be a matter of decision for all, so that one means of salvation should be established for all, receiving testimony from all, both from those belonging to it who were its friends, and by those having no connection with it who were its enemies. For that evidence is most trustworthy and true which elicits even from its adversaries striking testimonies on its behalf. .
