The term 'Bishop Staff' refers to the four items used by a bishop in the Catholic Church. The first item is the CROSIER, which is a staff with a curved top that is carried by a bishop as a symbol of his pastoral office. The second item is the SEE, which is the official seat of a bishop's authority. The third item is the MITRE, which is a tall, pointed hat worn by a bishop during liturgical ceremonies. Finally, the fourth item is the JOEY, which is a short cape worn by a bishop over his shoulders. Together, these four items make up the Bishop Staff.
