Subdeacon is a minor order of ministry for men in various branches of Christianity. The subdeacon has a specific liturgical role and is placed below the deacon and above the acolyte in the order of precedence.
An acolyte is an assistant or follower assisting the celebrant in a religious service or procession. In many Christian denominations, an acolyte is anyone performing ceremonial duties such as lighting altar candles. In others, the term is used for one who has been inducted into a particular liturgical ministry, even when not performing those duties.
An altar server is a lay assistant to a member of the clergy during a Christian liturgy. An altar server attends to supporting tasks at the altar such as fetching and carrying, ringing the altar bell, helping bring up the gifts, and bringing up the liturgical books, among other things. If young, the server is commonly called an altar boy or altar girl. In some Christian denominations, altar servers are known as acolytes.
In some Christian denominations, a reader or lector is the person responsible for reading aloud excerpts of scripture at a liturgy. In early Christian times the reader was of particular value due to the rarity of literacy.
The hierarchy of the Catholic Church consists of its bishops, priests, and deacons. In the ecclesiological sense of the term, "hierarchy" strictly means the "holy ordering" of the church, the Body of Christ, so to respect the diversity of gifts and ministries necessary for genuine unity.
Intinction is the Eucharistic practice of partly dipping the consecrated bread, or host, into the consecrated wine before consumption by the communicant.
Validity and liceity are concepts in the Catholic Church. Validity designates an action which produces the effects intended; an action which does not produce the effects intended is considered "invalid". Liceity designates an action which has been performed legitimately; an action which has not been performed legitimately is considered "illicit". Some actions can be illicit, but still be valid.
A Eucharistic minister, also known as a communion steward, is an individual that assists in the distribution of Holy Communion to the congregation of a Christian Church.
Eucharist is the name that Catholic Christians give to the sacrament by which, according to their belief, the body and blood of Christ are present in the bread and wine consecrated during the Catholic eucharistic liturgy, generally known as the Mass. The definition of the Eucharist in the 1983 Code of Canon Law as the sacrament where Christ himself “is contained, offered, and received” points to the three aspects of the Eucharist according to Catholic theology: the real presence of Christ in the Eucharist, Holy Communion, and the holy sacrifice of the Mass.
The Mass is the central liturgical service of the Eucharist in the Catholic Church, in which bread and wine are consecrated and become the body and blood of Christ. As defined by the Church at the Council of Trent, in the Mass "the same Christ who offered himself once in a bloody manner on the altar of the cross, is present and offered in an unbloody manner". The Church describes the Mass as the "source and summit of the Christian life", and teaches that the Mass is a sacrifice, in which the sacramental bread and wine, through consecration by an ordained priest, become the sacrificial body, blood, soul, and divinity of Christ as the sacrifice on Calvary made truly present once again on the altar. The Catholic Church permits only baptised members in the state of grace to receive Christ in the Eucharist.
The sacrament of holy orders in the Catholic Church includes three orders: bishops, priests, and deacons, in decreasing order of rank, collectively comprising the clergy. In the phrase "holy orders", the word "holy" means "set apart for a sacred purpose". The word "order" designates an established civil body or corporation with a hierarchy, and ordination means legal incorporation into an order. In context, therefore, a group with a hierarchical structure that is set apart for ministry in the Church.
The Anglican ministry is both the leadership and agency of Christian service in the Anglican Communion. Ministry commonly refers to the office of ordained clergy: the threefold order of bishops, priests and deacons. More accurately, Anglican ministry includes many laypeople who devote themselves to the ministry of the church, either individually or in lower/assisting offices such as lector, acolyte, sub-deacon, Eucharistic minister, cantor, musicians, parish secretary or assistant, warden, vestry member, etc. Ultimately, all baptized members of the church are considered to partake in the ministry of the Body of Christ.
The priesthood is the office of the ministers of religion, who have been commissioned ("ordained") with the Holy orders of the Catholic Church. Technically, bishops are a priestly order as well; however, in layman's terms priest refers only to presbyters and pastors. The church's doctrine also sometimes refers to all baptised (lay) members as the "common priesthood", which can be confused with the ministerial priesthood of the consecrated clergy.
Canon 915, one of the canons in the 1983 Code of Canon Law of the Latin Church of the Catholic Church, forbids the administration of Holy Communion to those upon whom the penalty of excommunication or interdict has been imposed or declared, or who obstinately persist in manifest grave sin:
Those who have been excommunicated or interdicted after the imposition or declaration of the penalty and others obstinately persevering in manifest grave sin are not to be admitted to holy communion.
This is a glossary of terms used within the Catholic Church. Some terms used in everyday English have a different meaning in the context of the Catholic faith, including brother, confession, confirmation, exemption, faithful, father, ordinary, religious, sister, venerable, and vow.
There are seven sacraments of the Catholic Church, which according to Catholic theology were instituted by Jesus Christ and entrusted to the Church. Sacraments are visible rites seen as signs and efficacious channels of the grace of God to all those who receive them with the proper disposition.
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 and non-clergy. 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.
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".
In the canon law of the Catholic Church, a person is a subject of certain legal rights and obligations. Persons may be distinguished between physical and juridic persons. Juridic persons may be distinguished as collegial or non-collegial, and public or private juridical persons. The Holy See and the Catholic Church as such are not juridic persons since juridic persons are created by ecclesiastical law. Rather, they are moral persons by divine law.
In the Catholic Church, communicatio in sacris, also called communicatio in divinis or communicatio in ritibus, designates the regulations for the partaking of a Catholic person to a non-Catholic sacrament or liturgical celebration, or for the partaking of a non-Catholic person to a Catholic sacrament or liturgical celebration. The expression is also used to refer to said acts of partaking themselves.
