One of my favorite things about getting to do what I do serving as a pastor-theologian is study Scripture and theology alongside one another and seek to apply God's word by His Spirit in our local context here at Redemption Church in Seattle. I came across this piece today and it blessed me tremendously as I was thinking about how Jesus' death accomplishes reconciliation not only with God but with one another. The following excerpt is wonderful.
Christ's Sacrifice Provides Reconciliation of Persons to One Another
“Christ died so that believing sinners may enjoy also reconciliation to each other. Christ’s sacrifice provides for a new community, a fellowship of sinners at peace with God and so at peace with one another. Because of the cross Samaritans and Gentiles could be united with Jews in Christ’s body, the church. Having put to death their hostility, he made the Jew and Gentile one, destroying the dividing wall by abolishing the law and giving both access to the Father by the Spirit (Eph. 2:14-18). At one time we were “uncircumcised,… separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of promise, without hope and without God in the world” (vv. 11-12). “But now in Christ Jesus you who once were far away have been brought near through the blood of Christ.” So he is “our peace” (v.14). “Christ loved the church and gave himself up for her” (5:25). Commitment to life under the cross–not race or economic status–reconciles sinners to one another. People living under the cross should not be expected to meet extraneous requirements for membership in a church.
Because they are forgiven by grace, church members seek to be graciously forgiving. Because they are liberated from the reign of sin (Rom. 6:12), God’s people rejoice in making peace with others who have been reconciled to God through faith in Christ. The crucified Christ provides the one foundation on which to build a church (1 Cor. 3:10-15) because he bought the Church of God “with his own blood” (Acts 20:28). Christian homes, churches, and organizations enjoy reconciliation and peace to the extent that they’re just and loving communities. Families and churches respect members’ dignity and rights, and lovingly families and churches go beyond justice and accept mercy and love.”
