Mystery celebrated
Christ gives the Eucharist and the ministerial priesthood to the Church and manifests the commandment of fraternal charity.
The celebration belongs to the Church's objective liturgical worship; its doctrine is expressed in the proper prayers, readings, chants, and ritual observance appointed by the liturgical books.[2]
Date and calendar
The Evening Mass of the Lord's Supper begins the Paschal Triduum on the Thursday before Easter.
Its actual observance in a given year follows the universal table of liturgical days, including the rules for concurrence, occurrence, omission, and transfer.[3]
Celebration
The Mass and the Liturgy of the Hours use the propers assigned to the day. The rank determines whether the celebration begins with First Vespers, includes the Gloria or Creed, and supersedes another observance.
