What is “the sacrament” of the Eucharist?

The story behind the answer

The Eucharist is the sacrament in which bread and wine are consecrated and received as the Body and Blood of Christ, uniting believers with Jesus and with one another. It traces to the Last Supper, when Christ commanded, “Do this in memory of me.” By receiving it, the faithful “communicate” in Christ’s life—hence the traditional term “communion.” Baptism, Confirmation, and Anointing of the Sick are distinct sacraments with different purposes.

In the Middle Ages, this rite was the heart of Christian worship. The Fourth Lateran Council (1215) defined transubstantiation, and the Feast of Corpus Christi (13th century) celebrated the real presence with processions and devotion. Many laypeople received infrequently, leading to the elevation of the Host so they could adore even without partaking. Medieval practice often reserved the chalice to clergy, reflecting deep reverence for the sacrament’s holiness.
