Answer the following question: Information: - Petrus Canisius Jean van Lierde , O.S.A. ( 22 April 1907 -- 12 March 1995 ) , served forty years from 1951 to 1991 as Vicar General for the Vatican City State , and was the longest serving Vatican official in that position . - A vicar (Latin: "vicarius") is a representative, deputy or substitute; anyone acting "in the person of" or agent for a superior (compare "vicarious" in the sense of "at second hand"). Linguistically, "vicar" is cognate with the English prefix "vice", similarly meaning "deputy". The title appears in a number of Christian ecclesiastical contexts, but also as an administrative title, or title modifier, in the Roman Empire. In addition, in the Holy Roman Empire a local representative of the emperor, perhaps an archduke, might be styled "vicar". - A vicar general is the principal deputy of the bishop of a diocese for the exercise of administrative authority and possesses the title of local ordinary. As vicar of the bishop, the vicar general exercises the bishop's ordinary executive power over the entire diocese and, thus, is the highest official in a diocese or other particular church after the diocesan bishop or his equivalent in canon law. The title normally occurs only in Western Christian churches, such as the Latin Church of the Catholic Church and the Anglican Communion. The title for the equivalent officer in the Eastern churches is protosyncellus and in the Anglican Communion is archdeacon. - A protosyncellus or protosynkellos () is the principal deputy of the bishop of an eparchy for the exercise of administrative authority in an Eastern Orthodox or Eastern Catholic church. The equivalent position in the Western Christian churches is vicar general. - The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with more than 1.27billion 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. - Canon law is the body of laws and regulations made by ecclesiastical authority (Church leadership), for the government of a Christian organization or church and its members. It is the internal ecclesiastical law, or operational policy, governing the Catholic Church (both the Latin Church and the Eastern Catholic Churches), the Eastern Orthodox and Oriental Orthodox churches, and the individual national churches within the Anglican Communion. The way that such church law is legislated, interpreted and at times adjudicated varies widely among these three bodies of churches. In all three traditions, a canon was originally a rule adopted by a church council; these canons formed the foundation of canon law. - The word diocese is derived from the Greek term "" meaning "administration". When now used in an ecclesiastical sense, it refers to a territorial unit of administration. In the Western Church, the district is under the supervision of a bishop (who may have assistant bishops to help him or her) and is divided into parishes under the care of priests; but in the Eastern Church, the word denotes the area under the jurisdiction of a patriarch and the bishops under his jurisdiction administer parishes. This structure of church governance is known as episcopal polity. - An archdeacon is a senior clergy position in the Syriac Orthodox Church, Church of the East, Chaldean Catholic Church, Anglican Communion, St Thomas Christians, Eastern Orthodox churches and some other Christian denominations, above that of most clergy and below a bishop. In the High Middle Ages it was the most senior diocesan position below a bishop in the Roman Catholic Church. An archdeacon is often responsible for administration within an archdeaconry, which is the principal subdivision of the diocese. The "Oxford Dictionary of the Christian Church" has defined an archdeacon as "A cleric having a defined administrative authority delegated to him by the bishop in the whole or part of the diocese." The office has often been described metaphorically as that of "oculus episcopi", the "bishop's eye". What entity does 'petrus canisius van lierde' has the relation 'position held' with?
