Installation (Christianity)

Installation is a Christian liturgical act that formally allows a cleric to assume the office of his appointed position at a particular place such as a cathedral. The term arises from the act of symbolically leading the prelate to their stall or throne within the cathedral or other place of worship (the word "cathedral" derives from the cathedra, the bishop's or archbishop's throne) representing the office of the position.
