'Corpus Christi' (
Latin for ''Body of
Christ'') is a
Christian feast in honour of the Holy
Eucharist. It was originally assigned to the Thursday following
Trinity Sunday, thereby mirroring
Holy Thursday, the Thursday of
Holy Week, the day on which Christians commemorate
The Last Supper of
Jesus Christ and
his apostles, seen as the first Holy Eucharist. Many English-speaking countries celebrate the Feast of Corpus Christi on the Sunday after Trinity Sunday - on the Sunday after the traditional Thursday celebration in other countries. It is customary on this day, after Mass, to hold processions (often outdoors) with the Host followed by
Benediction of the Blessed Sacrament.
The appearance of Corpus Christi as a feast in the Christian calendar was primarily due to the petitions of the thirteenth-century
Augustinian nun
Juliana of Liège. From her youth she claimed that God had been instructing her to establish a feast day for the Eucharist and later in life petitioned the learned Dominican
Hugh of St-Cher, Jacques Pantaléon (
Archdeacon of Liège and later
Pope Urban IV) and
Robert de Thorete,
Bishop of Liège. At that time bishops could order feasts in their
dioceses, so in
1246 Bishop Robert convened a
synod and ordered a celebration of Corpus Christi to be held each year thereafter. The decree is preserved in
Anton Joseph Binterim's ''Vorzüglichsten Denkwürdigkeiten der Christkatholischen Kirche'', together with parts of the first
liturgy written for the occasion.
The celebration of Corpus Christi only became widespread after both Juliana and Bishop Robert had died. In
1263 Pope Urban IV, investigated claims of a miracle in which blood had issued from a
host. One alternate, but incorrect, theory is that the blood was actually a clustering of ''
Serratia marcescens'', a reddish bacteria that often grows on bread. In this case, a bacteria growth can not account for the blood since it actually dripped from the Host and stained the corporal (square piece of cloth) below and it is still kept and displayed at the church. Regardless, in
1264 he issued the
papal bull ''
Transiturus'' in which Corpus Christi was made a feast day. A new liturgy for the celebration was written by
Thomas Aquinas.
While the institution of the Eucharist is celebrated on Holy Thursday, the joy of what is referred to in Greek as "the Holy Gift" () cannot on that occasion be well expressed, because of the nearness of Good Friday. This is given as a reason for celebrating the Corpus Christi feast at a different time of year.
Corpus Christi is primarily celebrated by the
Roman Catholic Church and in
Anglo-Catholic churches; it is included in the calendars of some churches of the
Anglican Communion. In Roman Catholic parishes that use the
Mass of Paul VI, the feast is known as "the Feast of the Body and Blood of Christ". In the
Church of England it is known as 'The Day of Thanksgiving for the Institution of Holy Communion (Corpus Christi)' and has the status of a
Festival. It is also celebrated by the
Old Catholic Church and is commemorated in the liturgical calendars of the more
Latinized Eastern Catholic Churches.
In some
Catholic countries it is a
national holiday.
Date
The Feast of Corpus Christi, which is a
moveable feast, is celebrated on the Thursday after Trinity Sunday or, in countries where it is not a
Holy Day of Obligation, on the Sunday after Holy Trinity.
The earliest possible Thursday celebration falls on
21 May (as in 1818 and 2285), the latest on
24 June (as in 1943 and 2038). As is obvious, the Sunday celebrations fall three days later.
