Body of Christ is a term of
Christian theology, implicitly traceable to
Jesus's statement at the
Last Supper that "This is my body" in , and explicitly used by the Apostle
Paul in .
Roman Catholicism
In the
Roman Catholic tradition, the term "Body of Christ" refers not only to the body of Christ in spiritual realm, but also to two distinct though related things: the Church and reality of the
transubstantiated bread of the
Eucharist.
The Church
The first meaning that the Roman Catholic Church attaches to the expression "Body of Christ" is the Church. The
Catechism of the Catholic Church quotes with approval, as "summing up the faith of the holy doctors and the good sense of the believer", the reply of Saint
Joan of Arc to her judges: "About Jesus Christ and the Church, I simply know they're just one thing, and we shouldn't complicate the matter. In the same passage, it also quotes
Saint Augustine: "Let us rejoice then and give thanks that we have become not only Christians, but Christ himself. Do you understand and grasp, brethren, God's grace toward us? Marvel and rejoice: we have become Christ. For if he is the head, we are the members; he and we together are the whole man.... the fullness of Christ then is the head and the members. But what does 'head and members' mean? Christ and the Church."
Saint Paul the Apostle spoke of this unity of Christians with Christ, spoken of in the New Testament also in images such as that of the vine and the branches, in terms of a single body that has Christ as its head in ,, and , and .
According to the Catechism of the Catholic Church, "the comparison of the Church with the body casts light on the intimate bond between Christ and his Church. Not only is she gathered around him; she is united in him, in his body. Three aspects of the Church as the Body of Christ are to be more specifically noted: the unity of all her members with each other as a result of their union with Christ; Christ as head of the Body; and the Church as bride of Christ. The Catechism then spells out the significance of each of these three aspects.
To distinguish the Body of Christ in this sense from his physical body, the term "Mystical Body of Christ" is often used. This term was used as the first words, and so as the title, of the encyclical Mystici Corporis Christi of Pope Pius XII.
The reality of the bread consecrated in the Eucharist
While teaching that in the bread consecrated in the
Eucharist there is absolutely no change open to the senses or to scientific investigation, the Catholic Church has always believed that the reality of the bread is changed into that of the body of Christ. To refer to this change of the "
substance" or considers particularly apt the term "
transubstantiation", but rejects that of "
consubstantiation", which suggests that the substance or reality of the bread remains after the consecration, instead of being converted or changed into that of the body of Christ. At the same time, it holds that all that can be examined either directly or by scientific investigation - what in
philosophy are called the "
accidents" (as opposed to the reality) - remains quite unchanged.
Thus, in the Roman Rite, the priest or other minister who gives the consecrated host to a communicant says: "The body of Christ", indicating what is held to be the reality of what is given.
Since the consecrated bread is believed to be truly the body of Christ, what remains of it after celebration of Mass is reverently kept in the church tabernacle, primarily for the purpose of taking Communion to the sick, but also to serve as a focal point for private devotion and prayer, and, on appropriate occasions, for public Eucharistic adoration.
Protestantism
"Body of Christ" is used by some
Protestants who style themselves as "
Bible-believing Christians" to describe believers in
Christ.
Jesus Christ is seen as the "head" of the body, which is the church. The "members" of the body are seen as members of the
Church.
Eastern Orthodoxy
The
Eastern Orthodox Church also believes that the Eucharistic elements of bread and wine become the actual Body and Blood of Christ. It has authoritatively used the term "
Transubstantiation" to describe this change, as in
The Longer Catechism of The Orthodox, Catholic, Eastern Church and in the decrees of the 1672
Synod of Jerusalem.
The Orthodox see the description of the Church (Ecclessia) as the "Body of Christ" as being inextricably connected to Holy Communion. According to St. Ignatius of Antioch (ca. 35-107), the unity of the Church is expressed in Eucharistic terms. Just as there are many offerings made throughout the world on any given day, and yet all partake of one and the same Body of Christ, so the Church, though existing in many separate localities, is only one.
