The church-community has, therefore, a very real impact on the life of the world. It gains space for Christ. For whatever is “in Christ” is no longer under the dominion of the world, of sin, or of the law. Within this newly created community, all the laws of this world have lost their binding force. This sphere in which brothers and sisters are loved with Christian love is subject to Christ; it is no longer subject to the world. The church-community can never consent to any restrictions of its service of love and compassion toward other human beings. For wherever there is a brother or sister, there Christ’s own body is present; and wherever Christ’s body is present, his church-community is also always present, which means I must also be present there. – Dietrich Bonhoeffer, Discipleship (DBWE 4), 236.
An interesting take on political theology: rather than being subject to two kingdoms (Church and World) as Lutherans hold, Bonhoeffer says that we as Christians are only subject to Christ, no matter where we are or what we’re doing. There is no sphere in which we stop being Christians, united to Christ and to one another; wherever one Christian is, the whole body of Christ is with them.
Does this mean that Christians are not subject to the laws of the land? Yes! Does that mean that we should not obey them? By no means! We are subject to Christ, who demands even more of us than any law; all just laws still fall short of the demands of discipleship, and so obeying the law is the least service to Christ. If a law is unjust, then it is contrary to Christ and must not be obeyed. Even though we should not obey an unjust law out of a sense of patriotism, refusal to obey an unjust law is again the least service to Christ. Whether we obey just laws or disobey unjust laws, in either case we do so incidentally, not out of service to the law or to the nation but out of service to Christ, to whom alone we are subject.
This can be seen in the way Christians live in community without coercion. Acts tells us that they held all things in common and gave to everyone as they had need, providing for widows, etc. They did not collect taxes amongst themselves to do so, but everyone gave as they were able, voluntarily. What the law requires under coercion, Christians give freely as service to Christ. In this way we are not subject to even the best laws, because we surpass them in Christ.
There is no such thing as a Christian criminal in this sense, because if we transgress so far as to break the law, we have long since failed to fulfill the demands of Christian discipleship, that is, to follow Christ. And when we break the law in service to Christ, we are not called criminals but martyrs, prisoners of conscience or faith.
So in all things seek first the kingdom of Heaven, and the law will be satisfied.
