Leavened vs. Unleavened Bread in the Eucharist
- 1 Cor 5:6-8
- Your boasting is not appropriate. Do you not know that a little yeast leavens all the dough? Clear out the old yeast, so that you may become a fresh batch of dough, inasmuch as you are unleavened. For our paschal lamb, Christ, has been sacrificed. Therefore let us celebrate the feast, not with the old yeast, the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.
- In the Old Covenant bread and wine were offered in sacrifice among the first fruits of the earth as a sign of grateful acknowledgment to the Creator. But they also received a new significance in the context of the Exodus: the unleavened bread that Israel eats every year at Passover commemorates the haste of the departure that liberated them from Egypt; the remembrance of the manna in the desert will always recall to Israel that it lives by the bread of the Word of God;156 their daily bread is the fruit of the promised land, the pledge of God's faithfulness to his promises. The "cup of blessing"157 at the end of the Jewish Passover meal adds to the festive joy of wine an eschatological dimension: the messianic expectation of the rebuilding of Jerusalem. When Jesus instituted the Eucharist, he gave a new and definitive meaning to the blessing of the bread and the cup.
- Jesus chose the time of Passover to fulfill what he had announced at Capernaum: giving his disciples his Body and his Blood:
- Then came the day of Unleavened Bread, on which the passover lamb had to be sacrificed. So Jesus sent Peter and John, saying, "Go and prepare the passover meal for us, that we may eat it. . . ." They went . . . and prepared the passover. And when the hour came, he sat at table, and the apostles with him. And he said to them, "I have earnestly desired to eat this passover with you before I suffer; for I tell you I shall not eat it again until it is fulfilled in the kingdom of God.". . . . And he took bread, and when he had given thanks he broke it and gave it to them, saying, "This is my body which is given for you. Do this in remembrance of me." And likewise the cup after supper, saying, "This cup which is poured out for you is the New Covenant in my blood."166
- By celebrating the Last Supper with his apostles in the course of the Passover meal, Jesus gave the Jewish Passover its definitive meaning. Jesus' passing over to his father by his death and Resurrection, the new Passover, is anticipated in the Supper and celebrated in the Eucharist, which fulfills the Jewish Passover and anticipates the final Passover of the Church in the glory of the kingdom.
Development of the Liturgy
Fr. Joseph Jungman -- in his The Mass of the Roman Rite -- states that:
"In the West, various ordinances appeared from the ninth century on, all demanding the exclusive use of unleavened bread for the Eucharist. A growing solicitude for the Blessed Sacrament and a desire to employ only the best and whitest bread, along with various scriptural considerations -- all favored this development.
"Still, the new custom did not come into exclusive vogue until the middle of the eleventh century. Particularly in Rome it was not universally accepted till after the general infiltration of various usages from the North" [Rome itself, conservative as alwaysr, did not change to unleavened bread until a few decades after the schism.]
~ Joseph Jungman, The Mass of the Roman Rite, volume II, pages 33-34
Fr. Jungman goes on to say that:
". . . the opinion put forward by J. Mabillon, Dissertatio de pane eucharistia, in his answer to the Jesuit J. Sirmond, Disquisitio de azymo, namely, that in the West it was always the practice to use only unleavened bread, is no longer tenable."
"Now, the fact that the West changed its practice and began using unleavened bread in the 8th and 9th century -- instead of the traditional leavened bread -- is confirmed by the research of Fr. William O'Shea, who noted that along with various other innovative practices from Northern Europe, the use of unleavened bread began to infiltrate into the Roman liturgy at the end of the first millennium, because as he put it, "Another change introduced into the Roman Rite in France and Germany at the time [i.e., 8th - 9th century] was the use of unleavened bread and of thin white wafers or hosts instead of the loaves of leavened bread used hitherto"
~ Fr. William O'Shea, The Worship of the Church, page 128
"Moreover, this change in Western liturgical practice was also noted by Dr. Johannes H. Emminghaus in his book, The Eucharist: Essence, Form, Celebration, because as he said:
"The Eucharistic bread has been unleavened in the Latin rite since the 8th century -- that is, it is prepared simply from flour and water, without the addition of leaven or yeast. . . . in the first millennium of the Church's history, both in East and West, the bread normally used for the Eucharist was ordinary 'daily bread,' that is, leavened bread, and the Eastern Church uses it still today; for the most part, they strictly forbid the use of unleavened bread. The Latin Church, by contrast, has not considered this question very important."
~ Dr. Johannes H. Emminghaus, The Eucharist: Essence, Form, Celebration, page 162
"Thus, with the foregoing information in mind, it is clear that the use of leavened bread by the Eastern Churches represents the ancient practice of the undivided Church, while the use of unleavened bread by the Western Church was an innovation introduced near the end of the first millennium."
Unleavened bread stays fresh longer, both before and after consecration.
Unleavened bread produces fewer crumbs.
Leavened bread is far better for the Eastern rite of communion, where the Body of Christ is soaked in the Precious Blood and served with a spoon.
- Freedom from sin
- Connection to Passover
- Infusion of the Holy Spirit
