Breaking the bread
Also called "the Fraction Rite."
See, Chapter 6 of the General Instructions of the Roman Missal for review of the use of bread and wine in the Liturgy of the Eucharist.
Jewish origins
The ancient Hebrews celebrated the Passover feast with bread and wine. There were seven "actions" associated with the celebration
- unleavened bread taken up
- prayer offered for blessing of the bread
- breaking of the bread
- distribution of pieces of the bread to all attending and consumption of it
- wine is mixed with water
- prayer of thanksgiving offered over the wine
- cup distributed to all attending to drink from it
Jesus and "breaking the bread"
Jesus, of course, redefined the Passover celebration: it remained a sacrificial celebration of Thanksgiving, only one in which he is the victim, not the sacrificial lamb.
Early Christian Church
We see from several sources how the early Christians did exactly as Jesus taught at the Last Supper.
> Didache
> Justin Martyr
The modern Roman Rite
In the medieval period forward, at least at large Masses and churches, it seems that the Gifts were brought to the altar in a procession of priests and deacons. It is likely that the bread was brought as whole loaves, which would then require "breaking" of the loaves. In the early Church the bread and wine were truly the offerings from the community, probably by households, to be presented to the Father in the form of the consecrated sacrifice of the Son. The Agnus Dei would be sung repeatedly during “fraction rite”, which would have taken much longer than a single verse, as the loaves would have to be literally broken into pieces – which fulfills what Christ did in the Gospel, ant not just at the Last Supper, such as in Luke 24:30. Interestingly, the word “bread” itself has etymological origins in “to break,” thus the “bread” is itself broken pieces of a loaf. (John 6:26 “loaves”).
This connection also helps us, as ushers, appreciate the role of the collection. Since the community does not “give” the bread and wine (the gifts), we participate in the sacrifice with an offering of money (there’s a reason for the terms “bread,” “dough” and “breadwinner”). I only recently learned that the current form of the Offertory and Presentation of the Gifts is a Vatican II innovation. It seems that in early Church people would bring their gifts of loaves and wine and the Deacons would put them directly on the altar before Mass. Medieval Masses included a formal Offertory procession, but with priests and deacons, not lay people.
