Although Peter seems to echo the opinion commonly held when he says that Jesus „went about doing good” (Act 10, 38), Jesus was accused of „casting out demons by Beelzebub, the ruler of the demons” (Mt 12, 24). In answer, he proposes a very short parable, the one of the „Strong one” tied up to seize his goods (Mt 12, 29). The present article studies the influence of this verse in the early Christian literature. The victory of the Saviour over evil is interpreted as the result of a cosmic fight (Origen) or as the merciful redemption of the human being and his restoration and vivification by the Holy Spirit (Irenaeus).
