Solemnity in the context of "Feast day"

Pentecost (also called Whit Sunday, Whitsunday or Whitsun) is a Christian holiday that takes place on the 49th day (50th day when inclusive counting is used) after Easter. It commemorates the descent of the Holy Spirit upon the Apostles of Jesus, Mary, and other followers of the Christ, while they were in Jerusalem celebrating the Feast of Weeks, as described in the Acts of the Apostles (Acts 2:1–31). Pentecost marks the "Birthday of the Church".

Pentecost is one of the Great feasts in the Eastern Orthodox Church, a Solemnity in the Roman Rite of the Catholic Church, a Festival in the Lutheran Churches, and a Principal Feast in the Anglican Communion. Many Christian denominations provide a special liturgy for this holy celebration. Since its date depends on the date of Easter, Pentecost is a "moveable feast". The Monday after Pentecost is a legal holiday in many European, African and Caribbean countries.

A military oath, also known as the oath of enlistment or swearing-in is an oath delivered by a conscript or volunteer upon enlisting into the state's armed forces. Various states have different phrasings of the oath, with the common component being the fidelity to the state and obedience to the superior officers. In the ancient times it was a very solemn procedure. In modern times, with many formal laws and regulations to maintain army discipline, it is still a solemn, but rather a formal event.

Principal Feasts are a type of observance in some churches of the Anglican Communion, including the Church of England, the Episcopal Church (United States), and the Anglican Church of Canada. All Principal Feasts are also Principal Holy Days, sharing equal status with those Principal Holy Days which are not Principal Feasts. They are considered to be the most significant type of observance, the others being Festivals, Lesser Festivals, and Commemorations. As with all Principal Holy Days, their observance is obligatory. The Anglican Principal Feasts and Principal Holy Days are somewhat comparable to Roman Catholic Solemnities and Holy days of obligation.

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 (Latin: Sollemnitas Sacratissimi Cordis Iesu) and celebrated on the second Friday after Trinity Sunday (see § Date, below). Some Anglican Franciscans keep the feast under the name of the Divine Compassion of Christ.

A memorial in the Roman Rite of the Catholic Church is a lower-ranked feast day in honour of a saint, the dedication of a church, or a mystery of the religion.

All feast days are ranked according to their importance and named as "solemnities", or "feasts", or "memorials".

The Doge on the Bucintoro near the Riva di Sant'Elena (also known as The Departure of the Bucentaur for the Ascension Day Ceremony, and other similar titles) is an oil painting on canvas by the Venetian painter Francesco Guardi. It was painted between 1775 and 1780, and is now in the Louvre in Paris.

This work is one of a series of twelve paintings representing the Solennità dogali (The Doge's Solemnities), in which the artist has faithfully copied the scenes drawn by Giovanni Antonio Canal and engraved by Giambattista Brustolon to commemorate the festivities at the coronation of the Doge Alvise Giovanni Mocenigo in 1763. This has led to some confusion, and the canvases were formerly attributed to Canaletto, though their style was quite unmistakably that of Guardi.

The Feast of Corpus Christi (Ecclesiastical Latin: Dies Sanctissimi Corporis et Sanguinis Domini Iesu Christi, lit. 'Day of the Most Holy Body and Blood of Jesus Christ the Lord'), 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 Catholic 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 feast of Corpus Christi was proposed by Thomas Aquinas, Doctor of the Church, to Pope Urban IV, in order to create a feast focused solely on the Holy Eucharist, emphasizing the joy of the Eucharist being the Body and Blood, Soul and Divinity of Jesus Christ. Having recognized in 1264 the authenticity of the Eucharistic Miracle of Bolsena, on input of Aquinas, the pontiff, then living in Orvieto, established the feast of Corpus Christi as a Solemnity and extended it to the whole Catholic Church.
