The church is not tied to a text in such a way that nothing will ever be done for the first time. In new situations those who ‘indwell’ the story of which Jesus is the centre will have to make new and risky decisions about what faithfulness to the Author of the story requires. There can be no drawing of a straight line from a text of scripture to a contemporary ethical decision; there will always be the requirement of a fresh decision in responsibility to the One whose story it is.

— Lesslie Newbigin, “Truth and Authority in Modernity”

If I understand the teaching of the New Testament on this matter, I understand the role of the Christian as that of being neither a conservative nor an anarchist, but a subversive agent… We do not spend enough of our energies training undercover agents.

“that ultimate subversion of all human power and authority”

[Peter’s horrified reaction at Jesus’ washing of his feet] is the reaction of normal human nature. That the disciple should wash his master’s feet is normal and proper. But if the master becomes a menial slave to the disciple, then all proper order is overturned…. All of us except those at the very bottom have a vested interest in keeping it so, for as long as we duly submit to those above us we are free to bear down on those below us. The action of Jesus subverts this order and threatens to destabilize all society. Peter’s protest is the protest of normal human nature.

… This is not just an acted lesson in humility; Peter could have understood that…. The foot washing is a sign of that ultimate subversion of all human power and authority which took place when Jesus was crucified by the decision of the “powers” that rule this present age. In that act the wisdom of this world was shown to be folly, and the “powers” of this world were disarmed (Col 2:15). But “flesh and blood” — ordinary human nature — is in principle incapable of understanding this. It is “to the Jew a scandal, to the Greek folly.” Only those whom the risen Christ will call and to whom the Holy Spirit will be given will know that this folly is the wisdom of God, and this weakness is the power of God. At that moment, as the man he is, Peter cannot understand. The natural man makes gods in his own image…. How can the natural man recognize the supreme God in the stooping figure of a slave, clad only with a loincloth?
