Catholic laity are the ordinary members of the Catholic Church who are neither clergy nor recipients of Holy Orders or vowed to life in a religious order or congregation. Their mission, according to the Second Vatican Council, is to "sanctify the world".
The laity (individual layman) forms the majority of the estimated over one billion Catholics in the world.
In the Catholic Church, an association of the Christian faithful or simply association of the faithful (Latin: consociationes christifidelium), sometimes called a public association of the faithful, is a group of baptized persons, clerics or laity or both together, who, according to the 1983 Code of Canon Law, jointly foster a more perfect life or promote public worship or Christian teaching, or who devote themselves to other works of the apostolate.
A 20th-century resurgence of interest in lay societies culminated in the Second Vatican Council, but lay ecclesial societies have long existed in forms such as sodalities (defined in the 1917 Code of Canon Law as associations of the faithful constituted as an organic body), confraternities (similarly defined as sodalities established for the promotion of public worship), medieval communes, and guilds.
In the Roman Catholic Church, the term minister is used with various meanings. Most commonly, the word refers to a person, either lay or ordained, who is commissioned to perform some act on behalf of the Catholic Church. It is not a particular office or rank of clergy, as is the case in some other Christian organisations; rather, minister may be used as a collective term for vocational or professional pastoral leaders including clergy (bishops, deacons, priests) and non-clergy (theologians and lay ecclesial ministers). It is also used in reference to the canonical and liturgical administration of sacraments, as part of some offices, and with reference to the exercise of the lay apostolate.
The Fourth Council of the Lateran or Lateran IV was convoked by Pope Innocent III in April 1213 and opened at the Lateran Palace in Rome on 11 November 1215. Due to the great length of time between the council's convocation and its meeting, many bishops had the opportunity to attend this council, which is considered by the Catholic Church to be the twelfth ecumenical council.
The council addressed a number of issues, including the sacraments, the role of the laity, the treatment of Jews and heretics, and the organization of the church. The decree mandating annual confession has been called "perhaps the most important legislative act in the history of the church."
Utraquism (from the Latin sub utraque specie, meaning "under both kinds"), also called Calixtinism (from chalice; Latin: calix, borrowed from Greek kalyx, "shell, husk"; Czech: kališníci), was a belief amongst Hussites, a pre-Protestant reformist Christian movement in fifteenth century Bohemia that communion under both kinds (both the consecrated host and the precious blood, as opposed to the consecrated host alone) should be administered to the laity during the celebration of the Eucharist. Communion in both kinds was a principal dogma of the Hussites and one of the Four Articles of Prague.
After the Hussite movement split into various factions early in the Hussite Wars, Hussites that emphasized the laity's right to communion under both kinds became known as Moderate Hussites, Utraquist Hussites, or simply Utraquists. The Utraquists were the largest Hussite faction.
The Sovereign Military Order of Malta (SMOM), officially the Sovereign Military Hospitaller Order of Saint John of Jerusalem, of Rhodes and of Malta, and commonly known as the Order of Malta or the Knights of Malta, is a Catholic lay religious order, traditionally of a military, chivalric, and noble nature. Though it possesses no territory, the order is considered a sovereign entity under international law.
The Order traces its institutional continuity with the Knights Hospitaller, a chivalric order that was founded about 1099 by the Blessed Gerard in the Kingdom of Jerusalem. The order is led by an elected prince and grand master. Its motto is Tuitio fidei et obsequium pauperum ("Defence of the faith and assistance to the poor").
Lay ecclesial ministry is the term adopted by the United States Conference of Catholic Bishops to identify the relatively new category of pastoral ministers in the Catholic Church who serve the Church but are not ordained. Lay ecclesial ministers are coworkers with the bishop alongside priests and deacons. In other contexts, these may be known as "instituted catechists", "pastoral workers", "pastoral associates", etc.
