Great Lent, or the Great Fast, is the most important fasting season of the church year within many denominations of Eastern Christianity. It is intended to prepare Christians for the greatest feast of the church year, Pascha (Easter).
The liturgical year, also called the church year, Christian year or kalendar, consists of the cycle of liturgical seasons in Christian churches that determines when feast days, including celebrations of saints, are to be observed, and which portions of Scripture are to be read either in an annual cycle or in a cycle of several years.
The Twelve Days of Christmas, also known as the Twelve Days of Christmastide, are the festive Christian season celebrating the Nativity.
The Byzantine Rite, also known as the Greek Rite or the Rite of Constantinople, is a liturgical rite that is identified with the wide range of cultural, devotional, and canonical practices that developed in the Eastern Christian church of Constantinople.
In the Eastern Orthodox Church, the feast of the Resurrection of Jesus, called Pascha (Easter), is the greatest of all holy days and as such it is called the "feast of feasts". Immediately below it in importance, there is a group of Twelve Great Feasts. Together with Pascha, these are the most significant dates on the Orthodox liturgical calendar. Eight of the great feasts are in honor of Jesus Christ, while the other four are dedicated to the Virgin Mary — the Theotokos.
Christmas Sunday is a name for the Sunday after Christmas.
The Eastern Orthodox liturgical calendar describes and dictates the rhythm of the life of the Eastern Orthodox Church. Passages of Holy Scripture, saints and events for commemoration are associated with each date, as are many times special rules for fasting or feasting that correspond to the day of the week or time of year in relationship to the major feast days.
The Paschal cycle, in Eastern Orthodox Christianity, is the cycle of the moveable feasts built around Pascha (Easter). The cycle consists of approximately ten weeks before and seven weeks after Pascha. The ten weeks before Pascha are known as the period of the Triodion, referring to the liturgical book that contains the services for this liturgical season. This period includes the three weeks preceding Great Lent, the "pre-Lenten period", the forty days of Lent, and Holy Week. The 50 days following Pascha are called the Pentecostarion, also named after the liturgical book.
Orthros or útrenya, in the Byzantine Rite of the Eastern Orthodox Church and the Eastern Catholic Churches, is the last of the four night offices, the other three being vespers, compline, and midnight office. Traditionally, in monasteries it is held daily so as to end immediately following sunrise, in contrast to parishes where it is held only on Sundays and feast days. It is often called matins after the office it most nearly corresponds to in Western Christian churches.
A synaxis is a liturgical assembly in Eastern Christianity, generally for the celebration of Vespers, Matins, Little Hours and the Divine Liturgy.
In Christianity, the Nativity Fast—or Fast of the Prophets in Ethiopian Orthodox Tewahedo Church and Eritrean Orthodox Tewahedo Church—is a period of abstinence and penance practiced by the Eastern Orthodox Church, Oriental Orthodox Church and Catholic Church in preparation for the Nativity of Jesus on December 25. Ethiopian and Eritrean Orthodox Churches commence the season on November 24 and end the season on the day of Ethiopian Christmas, which falls on January 7. The corresponding Western season of preparation for Christmas, which also has been called the Nativity Fast and St. Martin's Lent, has taken the name of Advent. The Eastern fast runs for 40 days instead of four or six weeks and thematically focuses on proclamation and glorification of the Incarnation of God, whereas the Western Advent focuses on three comings of Jesus Christ: his birth, reception of his grace by the faithful, and his Second Coming or Parousia.
"Octave" has two senses in Christian liturgical usage. In the first sense, it is the eighth day after a feast, reckoning inclusively, and so always falls on the same day of the week as the feast itself. The word is derived from Latin octava (eighth), with dies (day) understood. In the second sense, the term is applied to the whole period of these eight days, during which certain major feasts came to be observed.
The Pentecostarion is the liturgical book used by the Eastern Orthodox and Byzantine Catholic churches during the Paschal Season which extends from Pascha (Easter) to the Sunday following All Saints Sunday.
The All-night vigil is a service of the Eastern Orthodox and Byzantine Catholic churches consisting of an aggregation of the canonical hours of Compline, Vespers, Matins, and the First Hour. This service may be performed on any Sunday or major feast, any feast for which a Litia is prescribed; these feasts are marked in the Typikon and in liturgical calendars by a Greek cross printed in red in a properly shaped semicircle [open at the top].
Eastern Orthodox worship in this article is distinguished from Eastern Orthodox prayer in that 'worship' refers to the activity of the Christian Church as a body offering up prayers to God while 'prayer' refers to the individual devotional traditions of the Orthodox.
Lazarus Saturday in Eastern Christianity refers to the moveable feast before Palm Sunday to which it is liturgically linked. It celebrates the raising of Lazarus of Bethany. Bethany is recorded in the New Testament as a small village in Judaea, the home of the siblings Mary of Bethany, Martha, and Lazarus, as well as that of Simon the Leper.
A liturgical book, or service book, is a book published by the authority of a church body that contains the text and directions for the liturgy of its official religious services.
The Dismissal is the final blessing said by a Christian priest or minister at the end of a religious service. In liturgical churches the dismissal will often take the form of ritualized words and gestures, such as raising the minister's hands over the congregation, or blessing with the sign of the cross. The use of a final blessing at the end of a liturgical service may be based upon the Priestly Blessing prescribed for the kohanim in the Torah.
Katabasia or Katavasia is a type of hymn, and the last troparion of an ode of a canon, chanted in the Eastern Orthodox Church and those Eastern Catholic Churches which follow the Byzantine Rite. Its name is derived from the Greek word katabasia for descent, so called because the cantors used to descend from their stalls and unite in the middle of the church to sing them.
Feasts of Jesus Christ are specific days of the year distinguished in the liturgical calendar as being significant days for the celebration of events in the life of Jesus Christ and his veneration, for the commemoration of his relics, signs and miracles. While Easter is treated everywhere as the central religious feast in the Christian liturgical year, the other feasts differ in the liturgical practice.
