Ordaining someone to the priesthood is a religious ceremony in which a person is officially admitted into the clergy. This process is known as ordination and is typically done by a bishop or other religious leader. The term 'ORDAIN' means to formally admit someone to the priesthood, and is derived from the Latin word 'ordinare, ' which means to arrange or order. Ordination is an important step in the life of a priest, and is often seen as a sign of commitment to the faith.
