Presbyterium is a modern term used in the Catholic Church and Eastern Catholic Churches after the Second Vatican Council in reference to a college of priests, in active ministry, of an individual particular church such as a diocese or eparchy. 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. Liturgically, within Catholicism, the presbyterium is the area of the church in which the clergy functions. It is more commonly called the sanctuary.
