1672 Certain blessings have a lasting importance because they consecrate persons to God, or reserve objects and places for liturgical use. Among those blessings which are intended for persons - not to be confused with sacramental ordination - are the blessing of the abbot or abbess of a monastery, the consecration of virgins and widows, the rite of religious profession and the blessing of certain ministries of the Church (readers, acolytes, catechists, etc.). The dedication or blessing of a church or an altar, the blessing of holy oils, vessels, and vestments, bells, etc., can be mentioned as examples of blessings that concern objects.
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authoritatively in the name of Jesus Christ that a person or object be protected against the power of the Evil One and withdrawn from his dominion, it is called exorcism.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.178 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.179
1674 Besides sacramental liturgy and sacramentals, catechesis must take into account the forms of piety and popular devotions among the faithful. The religious sense of the Christian people has always found expression in various forms of piety surrounding the Church’s sacramental life, such as the veneration of relics, visits to sanctuaries, pilgrimages, processions, the stations of the cross, religious dances, the rosary, medals,180 etc.
1675 These expressions of piety extend the liturgical life of the Church, but do not replace it. They "should be so drawn up that they harmonize with the liturgical seasons, accord with the sacred liturgy, are in some way derived from it and lead the people to it, since in fact the liturgy by its very nature is far superior to any of them."181
1676 Pastoral discernment is needed to sustain and support popular piety and, if necessary, to purify and correct the religious sense which underlies these devotions so that the faithful may advance in knowledge of the mystery of Christ.182 Their exercise is subject to the care and judgment of the bishops and to the general norms of the Church.
At its core the piety of the people is a storehouse of values that offers answers of Christian wisdom to the great questions of life. The Catholic wisdom of the people is capable of fashioning a vital synthesis. . . . It creatively combines the divine and the human, Christ and Mary, spirit and body, communion and institution, person and community, faith and homeland, intelligence and emotion. This wisdom is a Christian humanism that radically affirms the dignity of every person as a child of God, establishes a basic fraternity, teaches people to encounter nature and understand work, provides reasons for joy and humor even in the midst of a very hard life. For the people this wisdom is also a principle of discernment and an evangelical instinct through which they spontaneously sense when the Gospel is served in the Church and when it is emptied of its content and stifled by other interests.181
1677 Sacramentals are sacred signs instituted by the Church. They prepare men to receive the fruit of the sacraments and sanctify different circumstances of life.
1678 Among the sacramentals blessings occupy an important place. They include both praise of God for his works and gifts, and the Church’s intercession for men that they may be able to use God’s gifts according to the spirit of the Gospel.
1679 In addition to the liturgy, Christian life is nourished by various forms of popular piety, rooted in the different cultures. While carefully clarifying them in the light of faith, the Church fosters the forms of popular piety that express an evangelical instinct and a human wisdom and that enrich Christian life.
