On Holy Thursday before Easter Sunday, the Chrism Mass is held in every Catholic diocese. This special Mass serves two major purposes. The first is the blessing of the Holy Oils by the diocese bishop (in this case the highest bishop in the church, Pope Francis) for use in the coming year. These are: Oil of the Sick, Oil of Catechumens, and the Sacred Chrism. The oils are contained in the three large silver containers at the altar. The second is the renewal of the vows and commitments to the priesthood of the Roman Catholic Church.
