Chrism is a sacred oil used in various Christian traditions, particularly in the Catholic Church, Orthodox Church, and some Anglican communities. It is typically made from a mixture of olive oil and balsam, which gives it a pleasant fragrance. Chrism is consecrated by a bishop during a special ceremony, often held during Holy Week. This oil is used in several important rituals, including baptism, confirmation, and the anointing of priests and bishops. The use of Chrism symbolizes the presence of the Holy Spirit and the sealing of a person's faith, marking them as part of the Christian community.
