Sacramentals are sacred signs which in a sense imitate the sacraments. They signify certain effects, especially spiritual ones, which are obtained through the intercession of the Church. They prepare the faithful to receive the fruit of the sacraments and sanctify various circumstances of life.
Sacramentals may consist of material things or actions. 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. Some other sacramentals are: the Sign of the Cross, use of holy water, blessed rosaries, crucifixes, scapulars and medals. Exorcism (Expulsion of demons) is also a sacramental.
