Please answer the following question: Information:  - A nun is a member of a religious community of women, typically one living under vows of poverty, chastity, and obedience. She may have decided to dedicate her life to serving all other living beings, or she might be an ascetic who voluntarily chose to leave mainstream society and live her life in prayer and contemplation in a monastery or convent. The term "nun" is applicable to Catholics (eastern and western traditions), Orthodox Christians, Anglicans, Lutherans, Jains, Buddhists, Taoists, Hindus and some other religious traditions.  - A saint, also historically known as a hallow, is a term used for a person who is recognized as having an exceptional degree of holiness or likeness to God. Depending on the context and denomination, the term also retains its original Christian meaning, as any believer who is "in Christ" and in whom Christ dwells, whether in Heaven or on Earth. In Anglican, Roman Catholic, Eastern Orthodox, Lutheran, and Oriental Orthodox doctrine, all of their faithful deceased in Heaven are considered to be saints, but some are considered worthy of greater honor or emulation; official ecclesiastical recognition, and consequently veneration, is given to some saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church.  - A convent is either a community of priests, religious brothers or religious sisters (nuns); or the building used by the community, particularly in the Roman Catholic Church and in the Anglican Communion. Etymology and usage. The term derives via Old French from Latin "conventus", perfect participle of the verb "convenio", meaning to convene, to come together. The original reference was to the gathering of mendicants who spent much of their time travelling.  Technically, a "monastery" or "nunnery" is a community of monastics, whereas a "friary" or "convent" is a community of mendicants, and a "canonry" a community of canons regular. The terms "abbey" and "priory" can be applied to both monasteries and canonries; an abbey is headed by an Abbot, and a priory is a lesser dependent house headed by a Prior.  - The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with more than 1.27 billion members worldwide. As one of the oldest religious institutions in the world, it has played a prominent role in the history of Western civilisation. Headed by the Bishop of Rome, known as the pope, its doctrines are summarised in the Nicene Creed. The Catholic Church is notable within Western Christianity for its sacred tradition and seven sacraments.  - Leoba ( also Lioba and Leofgyth ) ( c. 710 -- 28 September 782 ) was an Anglo - Saxon nun who was part of Boniface 's mission to the Germans , and a saint .  - Canonization is the act by which the Catholic Church and Anglican Communion declare that a person who has died was a saint, upon which declaration the person is included in the canon, or list, of recognized saints.
