Pope
Pope is the title attributed to the highest authoritave figure and spirital leader of the Christian church. The office of the pope is known as the Papacy. His ecclesiastical jurisdiction is often called the "Holy See", or the "Apostolic See" based upon the Church tradition that the Apostles Saint Peter and Saint Paul were martyred in Rome. The pope is also head of state of Vatican City, a sovereign city-state entirely enclaved within the city of Rome.

Bishop
A bishop is an ordained or consecrated member of the Christian clergy who is generally entrusted with a position of authority and oversight. Within the Catholic Church, Eastern Orthodox, Oriental Orthodox Churches, in the Assyrian Church of the East, in the Independent Catholic Churches, and in the Anglican churches, bishops claim apostolic succession, a direct historical lineage dating back to the original Twelve Apostles.

Priest
A priest is a person authorized to perform the sacred rites of a religion, especially as a mediatory agent between humans and deities. They also have the authority or power to administer religious rites; in particular, rites of sacrifice to, and propitiation of, a deity or deities. Their office or position is the priesthood, a term which also may apply to such persons collectively.

Vicar
A vicar is a representative, deputy or substitute; anyone acting "in the person of" or agent for a superior. The Pope uses the title Vicarius Christi, meaning, the vicar of Christ. An apostolic vicar is a bishop or priest who heads a missionary particular Church that is not yet ready to be a full diocese - he stands as the local representative of the Pope, in the Pope's role as bishop of all unorganized territories.

Reverend
A reverend is a style most often used as a prefix to the names of Christian clergy and ministers. There are sometimes differences in the way the style is used in different countries and church traditions. The Reverend is correctly called a style but is often and in some dictionaries called a title, form of address or title of respect.[1][2] The style is also sometimes used by leaders in non-Christian religions such as Judaism and Buddhism.

The term "nun" is applicable to Catholics – both eastern and western traditions – Orthodox Christians, Anglicans, Lutherans, Jains, Buddhists, Taoists, and Hindus.
