Today, Catholics celebrate the Feast of Corpus Christi

The Feast of Corpus Christi (Latin for Body of Christ) is a Latin Rite liturgical solemnity celebrating the tradition and belief in the physical body and blood of Jesus Christ and his Real Presence in the Eucharist.

In the present Roman Missal, the feast is designated the solemnity of The Most Holy Body and Blood of Christ. It is also celebrated in some Anglican, Lutheran and Old Catholic Churches who hold similar beliefs regarding the Real Presence.

The feast is liturgically celebrated either on the Thursday after Trinity Sunday or, "where the Solemnity of the Most Holy Body and Blood of Christ is not a Holy Day of Obligation, it is assigned to the Sunday after the Most Holy Trinity as its proper day". At the end of Holy Mass, there is often a procession of the Blessed Sacrament, generally displayed in a monstrance. The procession is followed by Benediction of the Blessed Sacrament.

A notable Eucharistic procession is that presided over by the Pope each year in Rome, where it begins at the Archbasilica of St. John Lateran and makes its way to the Basilica of Saint Mary Major, where it concludes with Benediction of the Blessed Sacrament.
