The oil of chrism is a special oil used in several Christian traditions, including Catholicism, Anglicanism, and Eastern Orthodoxy. It is typically used in baptism, confirmation, and ordination, as well as in the consecration of churches and altars.
The oil of chrism is a mixture of olive oil and balsam, a fragrant resin. In Catholicism and Anglicanism, it is blessed by a bishop during the Holy Week liturgy, and in Eastern Orthodoxy, it is blessed by the patriarch during the Great Week leading up to Easter.
The use of the oil of chrism dates back to early Christianity, and it is mentioned in several passages of the Bible. In the Old Testament, the anointing of kings and priests with oil was a common practice, and in the New Testament, Jesus himself is anointed with oil by a woman in preparation for his burial.
