Baptism is a Christian sacrament of initiation and adoption, almost invariably with the use of water. It may be performed by sprinkling or pouring water on the head, or by immersing in water either partially or completely, traditionally three times, once for each person of the Trinity. The synoptic gospels recount that John the Baptist baptised Jesus. Baptism is considered a sacrament in most churches, and as an ordinance in others. Baptism according to the Trinitarian formula, which is done in most mainstream Christian denominations, is seen as being a basis for Christian ecumenism, the concept of unity amongst Christians. Baptism is also called christening, although some reserve the word "christening" for the baptism of infants. In certain Christian denominations, such as the Catholic Churches, Eastern Orthodox Churches, Oriental Orthodox Churches, Assyrian Church of the East, and Lutheran Churches, baptism is the door to church membership, with candidates taking baptismal vows. It has also given its name to the Baptist churches and denominations.
Infant baptism is the practice of baptizing infants or young children. Infant baptism is also called christening by some faith traditions.
In Christian denominations that practice infant baptism, confirmation is seen as the sealing of the covenant created in baptism. Those being confirmed are known as confirmands. For adults, it is an affirmation of belief. It involves laying on of hands.
Marriage in the Catholic Church, also known as holy matrimony, is the "covenant by which a man and woman establish between themselves a partnership of the whole of life and which is ordered by its nature to the good of the spouses and the procreation and education of offspring", and which "has been raised by Christ the Lord to the dignity of a sacrament between the baptized". Catholic matrimonial law, based on Roman law regarding its focus on marriage as a free mutual agreement or contract, became the basis for the marriage law of all European countries, at least up to the Reformation.
Ne Temere was a decree issued in 1907 by the Roman Catholic Congregation of the Council regulating the canon law of the Church regarding marriage for practising Catholics. It is named for its opening words, which literally mean "lest rashly" in Latin.
Open communion is the practice of some Protestant Churches of allowing members and non-members to receive the Eucharist. Many but not all churches that practice open communion require that the person receiving communion be a baptized Christian, and other requirements may apply as well. In Methodism, open communion is referred to as the open table, meaning that all may approach the Communion table.
Interfaith marriage, sometimes called interreligious marriage or "mixed marriage", is marriage between spouses professing different religions. Although interfaith marriages are often established as civil marriages, in some instances they may be established as a religious marriage. This depends on religious doctrine of each of the two parties' religions; some prohibit interfaith marriage, and among others there are varying degrees of permissibility.
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.
The Pauline privilege is the allowance by the Roman Catholic Church of the dissolution of marriage of two persons not baptized at the time the marriage occurred. The Pauline privilege is drawn from the apostle Paul's instructions in the First Epistle to the Corinthians.
Catechesis is basic Christian religious education of children and adults, often from a catechism book. It started as education of converts to Christianity, but as the religion became institutionalized, catechesis was used for education of members who had been baptized as infants. As defined in the Catechism of the Catholic Church, paragraph 5 :
Catechesis is an education in the faith of children, young people and adults which includes especially the teaching of Christian doctrine imparted, generally speaking, in an organic and systematic way, with a view to initiating the hearers into the fullness of Christian life.
A defender of the bond is a Catholic Church official whose duty is to defend the marriage bond in the procedure prescribed for the hearing of matrimonial causes which involve the validity or nullity of a marriage already contracted. In current Canon Law the role is provided for in Book VII, Title 1, which deals with marriage processes.
Ligamen or vinculum is, in Roman Catholic canon law, an existing marriage tie, which constitutes an impediment to the contracting of a second marriage.
In the canon law of the Catholic Church, an impediment is a legal obstacle that prevents a sacrament from being performed either validly or licitly or both. The term is used most frequently in relationship to the sacraments of Marriage and Holy Orders. Some canonical impediments can be dispensed by the competent authority as defined in Catholic canon law.
An emergency baptism is a baptism administered to a person in danger of death. This can be done by a person not normally authorized to administer the sacraments.
Rebaptism in Christianity is the baptism of a person who has previously been baptized, usually in association with a denomination that does not recognize the validity of the previous baptism. When a denomination rebaptizes members of another denomination, it is a sign of significant differences in theology. Churches that practice exclusive believer's baptism, including Baptists and Churches of Christ, rebaptize those who were baptized as infants because they do not consider infant baptism to be valid.
Petrine privilege, also known as the privilege of the faith or favor of the faith, is a ground recognized in Catholic canon law allowing for dissolution by the Pope of a valid natural marriage between a baptized and a non-baptized person for the sake of the salvation of the soul of someone who is thus enabled to marry in the Church.
An interfaith marriage, also known as an interreligious marriage, is defined by Christian denominations as a marriage between a Christian and a non-Christian, whereas an interdenominational marriage is between members of two different Christian denominations, such as a Lutheran Christian wedding a Catholic Christian, for example.
Marital conversion is religious conversion upon marriage, either as a conciliatory act, or a mandated requirement according to a particular religious belief. Endogamous religious cultures may have certain opposition to interfaith marriage and ethnic assimilation, and may assert prohibitions against the conversion of one their own claimed adherents. Conversely, they may require the marital conversion of those who wish to marry one of their adherents.
Natural marriage is the name given in Catholic canon law to the covenant "by which a man and a woman establish between themselves a partnership of the whole of life and which is ordered by its nature to the good of the spouses and the procreation and education of offspring", and is distinguished from a sacramental or Christian marriage, in which the two parties involved are baptized.
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.
