Agnus Dei is the Latin name under which the "Lamb of God" is honoured within Christian liturgies descending from the historic Latin liturgical tradition, including those of Roman Catholicism, Lutheranism and Anglicanism. It is the name given to a specific prayer that occurs in these liturgies, and is the name given to the music pieces that accompany the text of this prayer.
Mass is the main Eucharistic liturgical service in many forms of Western Christianity. The term Mass is commonly used in the Catholic Church, Western Rite Orthodoxy, Old Catholicism, and Independent Catholicism. The term is also used in some Lutheran churches, as well as in some Anglican churches, and on rare occasion by other Protestant churches.
The Tridentine Mass, also known as the Traditional Latin Mass or the Traditional Rite, is the liturgy in the Roman Missal of the Catholic Church published from 1570 to 1962. Celebrated almost exclusively in Ecclesiastical Latin, it was the most widely used Eucharistic liturgy in the world from its issuance in 1570 until the introduction of the Mass of Paul VI.
Confession, in many religions, is the acknowledgment of one's wrong thoughts and actions (sins). This may occur directly to a god, to fellow people, or to a person acting as a mediator for a god.
Penance is any act or a set of actions done out of repentance for sins committed, as well as an alternate name for the Catholic, Lutheran, Eastern Orthodox, and Oriental Orthodox sacrament of Reconciliation or Confession. It also plays a part in confession among Anglicans and Methodists, in which it is a rite, as well as among other Protestants. The word penance derives from Old French and Latin paenitentia, both of which derive from the same root meaning repentance, the desire to be forgiven. Penance and repentance, similar in their derivation and original sense, have come to symbolize conflicting views of the essence of repentance, arising from the controversy as to the respective merits of "faith" and "good works". Word derivations occur in many languages.
An Act of Contrition is a Christian prayer genre that expresses sorrow for sins. It may be used in a liturgical service or be used privately, especially in connection with an examination of conscience. Special formulae for acts of contrition are in use in the Anglican, Catholic, Lutheran, Methodist and Reformed Churches.
The epiclesis refers to the invocation of one or several gods. In ancient Greek religion, the epiclesis was the epithet used as the surname given to a deity in religious contexts. The term was borrowed into the Christian tradition, where it designates the part of the Anaphora by which the priest invokes the Holy Spirit upon the Eucharistic bread and wine in some Christian churches. In most Eastern Christian traditions, the Epiclesis comes after the Anamnesis ; in the Western Rite it usually precedes. In the historic practice of the Western Christian Churches, the consecration is effected at the Words of Institution though during the rise of the Liturgical Movement, many denominations introduced an explicit epiclesis in their liturgies.
"Gloria in excelsis Deo" is a Christian hymn known also as the Greater Doxology and the Angelic Hymn/Hymn of the Angels. The name is often abbreviated to Gloria in Excelsis or simply Gloria.
Absolution is a theological term for the forgiveness imparted by ordained Christian priests and experienced by Christian penitents. It is a universal feature of the historic churches of Christendom, although the theology and the practice of absolution vary between Christian denominations.
The Exsultet, also known as the Easter Proclamation, is a lengthy sung proclamation delivered before the paschal candle, ideally by a deacon, during the Easter Vigil in the Roman Rite of Mass. In the absence of a deacon, it may be sung by a priest or by a cantor. It is sung after a procession with the paschal candle before the beginning of the Liturgy of the Word. It is also used in Anglican and various Lutheran churches, as well as other Western Christian denominations.
The Confiteor is one of the prayers that can be said during the Penitential Act at the beginning of Mass of the Roman Rite in the Catholic Church. It is also said in the Lutheran Church at the beginning of the Divine Service, and by some Anglo-catholic Anglicans before Mass.
The Roman Rite is the most common ritual family for performing the ecclesiastical services of the Latin Church, the largest of the sui iuris particular churches that comprise the Catholic Church. The Roman Rite governs rites such as the Roman Mass and the Liturgy of the Hours as well as the manner in which sacraments and blessings are performed.
The Sacrament of Penance is one of the seven sacraments of the Catholic Church, in which the faithful are absolved from sins committed after baptism and reconciled with the Christian community. During reconciliation mortal sins must be confessed and venial sins may be confessed for devotional reasons. According to the dogma and unchanging practice of the church, only those ordained as priests may grant absolution.
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 Divine Service is a title given to the Eucharistic liturgy as used in the various Lutheran churches. It has its roots in the Pre-Tridentine Mass as revised by Martin Luther in his Formula missae of 1523 and his Deutsche Messe of 1526. It was further developed through the Kirchenordnungen of the sixteenth and seventeenth centuries that followed in Luther's tradition.
Lay confession is confession in the religious sense, made to a lay person.
The Eucharist in the Lutheran Church refers to the liturgical commemoration of the Last Supper. Lutherans believe in the real presence of Christ in the Eucharist, affirming the doctrine of sacramental union, "in which the body and blood of Christ are truly and substantially present, offered, and received with the bread and wine."
In the Lutheran Church, Confession is the method given by Christ to the Church by which individual men and women may receive the forgiveness of sins; according to the Large Catechism, the "third sacrament" of Holy Absolution is properly viewed as an extension of Holy Baptism.
The Lutheran sacraments are "sacred acts of divine institution". Lutherans believe that, whenever they are properly administered by the use of the physical component commanded by God along with the divine words of institution, God is, in a way specific to each sacrament, present with the Word and physical component. They teach that God earnestly offers to all who receive the sacrament forgiveness of sins and eternal salvation. They teach that God also works in the recipients to get them to accept these blessings and to increase the assurance of their possession.
The General Confession is a prayer of contrition in various Christian denominations, including Lutheranism, Anglicanism, Methodism, and Roman Catholicism.
