Maundy Thursday or Holy Thursday, among other names, is the day during Holy Week that commemorates the Washing of the Feet (Maundy) and Last Supper of Jesus Christ with the Apostles, as described in the canonical gospels.
Holy Week is the most sacred week in the liturgical year in Christianity. For all Christian traditions, it is a moveable observance. In Eastern Christianity, which also calls it Great Week, it is the week following Great Lent and Lazarus Saturday, starting on the evening of Palm Sunday and concluding on the evening of Great Saturday. In Western Christianity, Holy Week is the sixth and last week of Lent, beginning with Palm Sunday and concluding on Holy Saturday.
The Feast of Corpus Christi, also known as the Solemnity of the Most Holy Body and Blood of Christ, is a Christian liturgical solemnity celebrating the Real Presence of the Body and Blood, Soul and Divinity of Jesus in the elements of the Eucharist; it is observed by the Latin Church, in addition to certain Western Orthodox, Lutheran, and Anglican churches. Two months earlier, the institution of the Eucharist at the Last Supper is observed on Maundy Thursday in a sombre atmosphere leading to Good Friday. The liturgy on that day also commemorates Christ's washing of the disciples' feet, the institution of the priesthood, and the agony in the Garden of Gethsemane.
The Paschal Triduum or Easter Triduum, Holy Triduum, or the Three Days, is the period of three days that begins with the liturgy on the evening of Maundy Thursday, reaches its high point in the Easter Vigil, and closes with evening prayer on Easter Sunday. It is a moveable observance recalling the Passion, Crucifixion, Death, burial, and Resurrection of Jesus, as portrayed in the canonical Gospels.
Genuflection or genuflexion is the act of bending a knee to the ground, as distinguished from kneeling which more strictly involves both knees. From early times, it has been a gesture of deep respect for a superior. Today, the gesture is common in the Christian religious practices of the Anglicanism, Lutheranism, the Catholic Church, and Western Rite Orthodoxy. The Latin word genuflectio, from which the English word is derived, originally meant kneeling with both knees rather than the rapid dropping to one knee and immediately rising that became customary in Western Europe in the Middle Ages. It is often referred to as "going down on one knee" or "bowing the knee". In Western culture, one genuflects on the left knee to a human dignitary, whether ecclesiastical or civil, while, in Christian churches and chapels, one genuflects on the right knee when the Sacrament is not exposed but in a tabernacle or veiled.
Eucharistic adoration is a Eucharistic devotional practice primarily in Western Catholicism, but also to a lesser extent in certain Lutheran and Anglican traditions, in which the Blessed Sacrament is adored by the faithful. This practice may occur either when the Eucharist is exposed, or when it is not publicly viewable because it is reserved in a place such as a church tabernacle.
A tabernacle or a sacrament house is a fixed, locked box in which the Eucharist is stored as part of the "reserved sacrament" rite. A container for the same purpose, which is set directly into a wall, is called an aumbry.
The Liturgy of the Presanctified Gifts is a Byzantine Rite liturgical service which is performed on the weekdays of Great Lent wherein communion is received from Gifts that are sanctified (consecrated) in advance, hence its name; this Divine Liturgy has no anaphora.
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.
Passiontide is a name for the last two weeks of Lent, beginning on the Fifth Sunday of Lent, long celebrated as Passion Sunday, and continuing through Lazarus Saturday. It commemorates the suffering of Christ. The second week of Passiontide is Holy Week, ending on Holy Saturday.
In the Roman Rite of the Catholic Church, Lutheranism, Methodism and Anglicanism, an altar bell is typically a small hand-held bell or set of bells. The primary reason for the use of such bells is to create a “joyful noise to the Lord” as a way to give thanks for the miracle taking place atop the altar.
Benediction of the Blessed Sacrament, also called Benediction with the Blessed Sacrament or the Rite of Eucharistic Exposition and Benediction, is a devotional ceremony, celebrated especially in the Roman Catholic Church, but also in some other Christian traditions such as Anglo-Catholicism, whereby a bishop, a priest, or a deacon blesses the congregation with the Eucharist at the end of a period of adoration.
During the Mass of the Faithful, the second part of the Mass, the elements of bread and wine are considered to have been changed into the veritable Body and Blood of Jesus Christ. The manner in which this occurs is referred to by the term transubstantiation, a theory of St. Thomas Aquinas, in the Roman Catholic Church. Members of the Orthodox, Anglican, and Lutheran communions also believe that Jesus Christ is really and truly present in the bread and wine, but they believe that the way in which this occurs must forever remain a sacred mystery. In many Christian churches some portion of the consecrated elements is set aside and reserved after the reception of Communion and referred to as the reserved sacrament. The reserved sacrament is usually stored in a tabernacle, a locked cabinet made of precious materials and usually located on, above, or near the high altar. In Western Christianity usually only the Host, from Latin: hostia, meaning "victim", is reserved, except where wine might be kept for the sick who cannot consume a host.
Anglican eucharistic theology is diverse in practice, reflecting the comprehensiveness of Anglicanism. Its sources include prayer book rubrics, writings on sacramental theology by Anglican divines, and the regulations and orientations of ecclesiastical provinces. The principal source material is the Book of Common Prayer, specifically its eucharistic prayers and Article XXVIII of the Thirty-Nine Articles. Article XXVIII comprises the foundational Anglican doctrinal statement about the Eucharist, although its interpretation varies among churches of the Anglican Communion and in different traditions of churchmanship such as Anglo-Catholicism and Evangelical Anglicanism.
Eucharist is the name that Catholics give to the sacrament by which, according to their belief, the body and blood of Christ are present in the bread and wine that are 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 Mass of the Lord's Supper, also known as A Service of Worship for Maundy Thursday, is a Holy Week service celebrated on the evening of Maundy Thursday. It inaugurates the Easter Triduum, and commemorates the Last Supper of Jesus with his disciples, more explicitly than other celebrations of the Mass.
The altar in the Catholic Church is used for celebrating the Sacrifice of the Mass.
The Mass of the Presanctified is Christian liturgy traditionally celebrated on Good Friday in which the consecration is not performed. Instead, the Blessed Sacrament that was consecrated at an earlier Mass and reserved is distributed.
The Seven Churches Visitation is a Christian, especially Latin Catholic, Lenten tradition to visit seven churches on the evening of Maundy Thursday. Following the Mass of the Lord's Supper, the Blessed Sacrament is placed on the Altar of Repose in the church for Adoration. During the Seven Churches Visitation, the faithful visit several churches – traditionally seven, very rarely fourteen, sometimes no set number depending upon the particular practice – to pray before the Blessed Sacrament in each church. The Seven Churches Visitation has been done in an ecumenical context, involving Christians of the Catholic, Methodist, Episcopal, Aglipayan, and Salvationist traditions, among others.
