In Christian theology, the term Body of Christ (Latin: Corpus Christi) has two main but separate meanings: it may refer to Jesus Christ's words over the bread at the celebration of the Jewish feast of Passover that "This is my body" in Luke 22:19–20 (see Last Supper), or it may refer to all individuals who are "in Christ" (1 Corinthians 12:12–14; see Christian Church).
As used by Paul in the Pauline epistles "Body of Christ" refers to all individuals who "heard the word of truth, the gospel of your salvation, believed in him, were sealed with the promised Holy Spirit" (Ephesians 1:13), "are being built together into a dwelling place for God by the Spirit" (Ephesians 2:22), are "joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love" (Ephesians 4:16).
