The body, in union with their bishop as a collective, is a symbol of the collaborative and collegial nature of their sacerdotal ministry as inspired by the reforms made during the Second Vatican Council.
The presbyterium is most visible during the ordination of new priests and bishops and the Mass of the Chrism: the Holy Thursday Mass where the blessing of the oils used in the sacraments of Baptism, Confirmation, Anointing of the Sick, and Holy Orders takes place.
[2] The presbyterate is another term used to refer to the sacerdotal collegiality of priests with their bishop, commonly used in the Anglican Communion.
Within churches which hold apostolic succession, it is reflected in the concelebration of the Eucharist, in joining the bishop in the laying on of hands on an ordinand to the priesthood, in collegial processions, at inductions, funerals, and other liturgical activities.
In the Catholic Church it is used to refer to the second order of priesthood - one is said to be "ordained to the presbyterate".
