Episode 900: The Holy Eucharist

The Eucharist (/ˈjuːkərɪst/; Greek: εὐχαριστία, translit. eucharistía, lit. "thanksgiving"), also known as Holy Communion and the Lord's Supper among other names, is a Catholic rite that is considered a sacrament in most churches, and as an ordinance in others. According to the New Testament, the rite was instituted by Jesus Christ during the Last Supper; giving his disciples bread and wine during a Passover meal, he commanded them to "do this in memory of me" while referring to the bread as "my body" and the cup of wine as "the blood of my covenant, which is poured out for many".

The elements of the Eucharist, bread (leavened or unleavened) and wine (or non-alcoholic grape juice), are consecrated on an altar or a communion table and consumed thereafter, usually on Sundays. Communicants, those who consume the elements, may speak of "receiving the Eucharist" as well as "celebrating the Eucharist". Catholics recognize a special presence of Christ in this rite, though they differ about exactly how, where, and when Christ is present.

The Catholic Church states that the Eucharist is the body and blood of Christ under the species of bread and wine. It maintains that by the consecration, the substances of the bread and wine actually become the substances of the body and blood of Jesus Christ (transubstantiation) while the appearances or "species" of the bread and wine remain unaltered (e.g. colour, taste, feel, and smell). The Eastern Orthodox and Oriental Orthodox churches agree that an objective change occurs of the bread and wine into the body and blood of Christ.
