Chrism is used in the administration of the Sacraments of Baptism, Confirmation, and Holy Orders, in the consecration of churches, chalices, patens, altars, and altar-stones, and in the solemn blessing of bells and baptismal water. The head of the newly-baptized is anointed with chrism, the forehead of the person confirmed, the head and hands of a bishop at his consecration, and the hands of a priest at his ordination. So are the walls of churches, which are solemnly consecrated, anointed with the same holy oil, and the parts of the sacred vessels used in the Mass which come in contact with the Sacred Species, as the paten and chalice. If it be asked why chrism has been thus introduced into the functions of the church liturgy, a reason is found in its special fitness for this purpose by reason of its symbolical significance. For olive-oil, being of its own nature rich, diffusive, and abiding, is fitted to represent the copious outpouring of sacramental grace, while balsam, which gives forth most agreeable and fragrant odours, typifies the innate sweetness of Christian virtue. Oil also gives strength and suppleness to the limbs, while balsam preserves from corruption. Thus anointing with chrism aptly signifies that fulness of grace and spiritual strength by which we are enabled to resist the contagion of sin and produce the sweet flowers of virtue. "For we are the good odour of Christ unto God" (2 Corinthians 2:15).
