The Chrism Mass is a unique and significant celebration in the life of the diocese. During this Mass, Bishop McGrattan blesses the oil of catechumens, used in baptism and the oil of the sick. He also prepares and consecrates the oil of chrism that is used in the sacraments of baptism, confirmation, and holy orders, as well as at the dedication of churches. When these oils are used throughout the diocese, the Bishop is symbolically present. The priests of the diocese concelebrate this Mass to manifest their unity with the Bishop and all renew their priestly vows. The actions that take place at the Chrism Mass are important for carrying out the daily ministry in each church in the diocese.
