CCC 438 Jesus’ messianic consecration reveals his divine mission, “for the name ‘Christ’ implies ‘he who anointed’, ‘he who was anointed’ and ‘the very anointing with which he was anointed’. The one who anointed is the Father, the one who was anointed is the Son, and he was anointed with the Spirit who is the anointing.’”1 His eternal messianic consecration was revealed during the time of his earthly life at the moment of his baptism by John, when “God anointed Jesus of Nazareth with the Holy Spirit and with power”, “that he might be revealed to Israel”2 as its Messiah. His works and words will manifest him as “the Holy One of God”.3

CCC 1673 When the Church asks publicly and authoritatively in the name of Jesus Christ that a person or object be protected against the power of the Evil One and withdrawn from his dominion, it is called exorcism. Jesus performed exorcisms and from him the Church has received the power and office of exorcizing.4 In a simple form, exorcism is performed at the celebration of Baptism. The solemn exorcism, called “a major exorcism,” can be performed only by a priest and with the permission of the bishop. The priest must proceed with prudence, strictly observing the rules established by the Church. Exorcism is directed at the expulsion of demons or to the liberation from demonic possession through the spiritual authority which Jesus entrusted to his Church. Illness, especially psychological illness, is a very different matter; treating this is the concern of medical science. Therefore, before an exorcism is performed, it is important to ascertain that one is dealing with the presence of the Evil One, and not an illness.5

CCC 2173 The Gospel reports many incidents when Jesus was accused of violating the sabbath law. But Jesus never fails to respect the holiness of this day.6 He gives this law its authentic and authoritative interpretation: “The sabbath was made for man, not man for the sabbath.”7 With compassion, Christ declares the sabbath for doing good rather than harm, for saving life rather than killing.8 The sabbath is the day of the Lord of mercies and a day to honor God.9 “The Son of Man is lord even of the sabbath.”10
