 The most significant liturgical acts reserved to priests in these traditions are the administration of the Sacraments, including the celebration of the Holy Mass or Divine Liturgy (the terms for the celebration of the Eucharist in the Latin and Byzantine traditions, respectively), and the Sacrament of Reconciliation, also called Confession.The sacraments of Anointing of the Sick (Extreme Unction) and Confirmation are also administered by priests, though in the Western tradition Confirmation is ordinarily celebrated by a bishop.In the East, Chrismation is performed by the priest (using oil specially consecrated by a bishop) immediately after Baptism, and Unction is normally performed by several priests (ideally seven), but may be performed by one if necessary.
