The Athanasian Creed — also called the Pseudo-Athanasian Creed or Quicunque Vult, which is both its Latin name and its opening words, meaning "Whosoever wishes" — is a Christian statement of belief focused on Trinitarian doctrine and Christology. Used by Christian churches since the early sixth century, it was the first creed to explicitly state the equality of the three hypostases of the Trinity. It differs from the Nicene-Constantinopolitan Creed and the Apostles' Creed in that it includes anathemas condemning those who disagree with its statements.
The Apostles' Creed, sometimes titled the Apostolic Creed or the Symbol of the Apostles, is a Christian creed or "symbol of faith".
Pentecost is a Christian holiday which takes place on the 49th day after Easter Day. It commemorates the descent of the Holy Spirit upon the Apostles of Jesus while they were in Jerusalem celebrating the Feast of Weeks, as described in the Acts of the Apostles. The Catholic Church believes the Holy Spirit descended upon Mary, the mother of Jesus, at the same time, as recorded in the Acts of the Apostles.
The liturgical year, also called the church year, Christian year, ecclesiastical calendar, or kalendar, consists of the cycle of liturgical days and seasons that determines when feast days, including celebrations of saints, are to be observed, and which portions of scripture are to be read.
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.
Liturgical colours are specific colours used for vestments and hangings within the context of Christian liturgy. The symbolism of violet, blue, white, green, red, gold, black, rose and other colours may serve to underline moods appropriate to a season of the liturgical year or may highlight a special occasion.
In the practice of Christianity, canonical hours mark the divisions of the day in terms of fixed times of prayer at regular intervals. A book of hours, chiefly a breviary, normally contains a version of, or selection from, such prayers.
The Feast of Corpus Christi, also known as the Solemnity of the Most Holy Body and Blood of Christ, is a liturgical solemnity celebrating the real presence of Christ in the Eucharist; the feast 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.
Ordinary Time is the part of the liturgical year in the liturgy of the Roman Rite, which falls outside the two great seasons of Christmastide and Eastertide, or their respective preparatory seasons of Advent and Lent. Ordinary Time thus includes the days between Christmastide and Lent, and between Eastertide and Advent. The liturgical color assigned to Ordinary Time is green. The last Sunday of Ordinary Time is the Solemnity of Christ the King.
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.
The Feast of the Sacred Heart is a solemnity in the liturgical calendar of the Roman Rite of the Catholic Church. According to the General Roman Calendar since 1969, it is formally known as the Solemnity of the Most Sacred Heart of Jesus and celebrated on the second Friday after Trinity Sunday Some Anglican Franciscans keep the feast under the name of the Divine Compassion of Christ.
The Feast of the Ascension of Jesus Christ commemorates the Christian belief of the bodily Ascension of Jesus into Heaven. It is one of the ecumenical feasts of Christian churches, ranking with the feasts of the Passion and Pentecost. Following the account of Acts 1:3 that the risen Jesus appeared for 40 days prior to his Ascension, Ascension Day is traditionally celebrated on a Thursday, the fortieth day of Easter according to inclusive counting, although some Christian denominations have moved the observance to the following Sunday, sometimes called Ascension Sunday. The day of observance varies by ecclesiastical province in many Christian denominations, as with Methodists and Catholics, for example.
Christian liturgy is a pattern for worship used by a Christian congregation or denomination on a regular basis. The term liturgy comes from Greek and means "public work". Within Christianity, liturgies descending from the same region, denomination, or culture are described as ritual families.
The Feast of the Transfiguration is celebrated by various Christian communities in honor of the transfiguration of Jesus. The origins of the feast are less than certain and may have derived from the dedication of three basilicas on Mount Tabor. The feast was present in various forms by the 9th century, and in the Western Church was made a universal feast celebrated on 6 August by Pope Callixtus III to commemorate the raising of the siege of Belgrade (1456).
"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) implied and understood. In the second sense, the term is applied to the whole eight-day period, during which certain major feasts came to be observed.
Catholic devotions are particular customs, rituals, and practices of worship of God or honour of the saints which are in addition to the liturgy of the Catholic Church. The United States Conference of Catholic Bishops describes devotions as "expressions of love and fidelity that arise from the intersection of one's own faith, culture and the Gospel of Jesus Christ". Devotions are not considered part of liturgical worship, even if they are performed in a church or led by a priest, but rather they are paraliturgical. The Congregation for Divine Worship at the Vatican publishes a Directory on Popular Piety and the Liturgy.
The Lutheran liturgical calendar is a listing which details the primary annual festivals and events that are celebrated liturgically by various Lutheran churches. The calendars of the Evangelical Lutheran Church in America (ELCA) and the Evangelical Lutheran Church in Canada (ELCIC) are from the 1978 Lutheran Book of Worship and the calendar of the Lutheran Church–Missouri Synod (LCMS) and the Lutheran Church–Canada (LCC) use the Lutheran Book of Worship and the 1982 Lutheran Worship. Elements unique to the ELCA have been updated from the Lutheran Book of Worship to reflect changes resulting from the publication of Evangelical Lutheran Worship in 2006. The elements of the calendar unique to the LCMS have also been updated from Lutheran Worship and the Lutheran Book of Worship to reflect the 2006 publication of the Lutheran Service Book.
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.
Pentecost season, also known Pentecostide, as well as the time of Sundays after Pentecost or Sundays after Trinity, is a liturgical period, celebrated by some Christian churches, which immediately follows the Easter season. Although the start and end dates vary by liturgical tradition, the season typically begins on the day of Pentecost and continues throughout the rest of the liturgical year, ending just before the season of Advent. The liturgical color for this period is typically green or red.
Protestant liturgy or Evangelical liturgy is a pattern for worship used by a Protestant congregation or denomination on a regular basis. The term liturgy comes from Greek and means "public work". Liturgy is especially important in the Historical Protestant churches, both mainline and evangelical, while Baptist, Pentecostal, and nondenominational churches tend to be very flexible and in some cases have no liturgy at all. It often but not exclusively occurs on Sunday.
