The term 'BISHOP's Assistant' refers to two different roles in the church. The first is a VICAR, which is a clergyman appointed by a BISHOP to assist him in his duties. The second is a DEAN, which is a senior official in the church hierarchy who is responsible for overseeing the spiritual and administrative affairs of a cathedral or other religious institution. Both Vicars and Deans are important members of the clergy and serve as assistants to the BISHOP.
