Christ's sacrificial body given for the church. At the Last Supper, Christ breaks the bread and names it: this is my body, which is broken for you (Matt 26:26; 1 Cor 11:24). The brokenness fulfills the Passover lamb pattern (Ex 12) where the lamb was killed and consumed by the household, yet without a bone being broken (John 19:36 explicitly applies Ex 12:46 to the cross). Christ's body is broken in death but kept in bone (Ps 34:20) — both fulfillments at once. In the Lord's Supper, the broken bread is the participation in this single sacrifice through which the church is constituted as His one body (1 Cor 10:17). The broken body of Christ creates the one body of the church.
