Catechism of the Catholic Church

The coming of God's kingdom means the defeat of Satan's: "If it is by the Spirit of God that I cast out demons, then the kingdom of God has come upon you." Jesus' exorcisms free some individuals from the domination of demons. They anticipate Jesus' great victory over "the ruler of this world." The kingdom of God will be definitively established through Christ's cross: "God reigned from the wood." (394, 1673, 440, 2816)
