Does our union with Christ have anything to say about Christian social justice? Todd Billings in chapter 4 of Union with Christ makes this vital connection:
"According to Calvin, the 'sum of the gospel' is the double grace of justification and sanctification, gifts that are inseparable yet distinct, received by the Spirit in union with Christ. With this view of the gospel . . . love of neighbor and, consequently, justice are folded in as an essential feature of the Spirit鈥檚 work of regeneration. A life of justice is not an optional part of the Christian life . . ." (107)
In Christ, believers are justified and sanctified, acquitted and made new. As Paul says: 鈥淥r don鈥檛 you know that all of us who were baptized into Christ Jesus were baptized into his death? We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life鈥 (Rom 6:3-4). This 鈥渘ew life鈥 is geared toward righteousness鈥攑ersonal and public righteousness. Part of what it means to be sanctified or regenerated in Christ is to have a new orientation, a new direction in life, namely, to seek your neighbor鈥檚 good, which may involve acts of 鈥渟ocial justice.鈥 If we have been united to Christ, then we will pursue justice, or at least should pursue it, instead of succumbing to the temptation to ignore injustice.
