The Corpus Christi procession may be held today, and/or on the External Solemnity next Sunday. The Blessed Sacrament is processed under a canopy. Additional altars of repose may be used along the procession route, with Benediction given there. (In hot regions the altars of repose are often deferred until the procession of Christ the King in October.) The final Benediction is given upon return to the church. The procession route should be decorated if possible; frequently carpets are fashioned out of flower petals or colored sawdust arranged in devotional designs. If the procession cannot be held outdoors, it may be held around the interior perimeter of the church.
During the seven days following the feast, where the Procession is held, two Masses of the Most Holy Eucharist (taken from the weekday votive Masses) may be celebrated as II class votive Masses.
Funerals are not permitted today.
Mass of the Feast; Gloria; Sequence Lauda Sion, Credo; common preface.
In the Mass which precedes the Procession, a second Host is consecrated and exposed in the Monstrance after Communion and before the ablutions. The remainder of the Mass continues coram Sanctissimo. Benedicamus Domino is said and the Last Gospel omitted, before the Procession departs. It is not proper on Corpus Christi to expose a Host that was previously consecrated at another Mass.
