But if Christians don’t get Jesus right, what chance is there that other people will bother much with him?

If you're a Christian you're just a shadow of your future self.

God will himself one day hold all humans, and all human governments, to account, but the church has the responsibility in the present to speak words of truth and judgment in advance of that final holding-to-account.

Part of the problem about authenticity is that virtues aren't the only things that are habit forming: the more someone behaves in a way that is damaging to self or to others, the more "natural" it will both seem and actually be. Spontaneity, left to itself, can begin by excusing bad behavior and end by congratulating vice.

Paul's vision, though, is starting small, with actual communities in which reconciliation and justice has to be practiced - like the rich/poor distinction in the Corinthian church, for instance, or the projected reconciliation between Philemon and Onesimus. But he clearly believes (Ephesians 3) that communities like this send a signal to the wider world that Jesus is Lord - which is aimed at then the whole world coming into line.

Indian leaders are saying, "You don't understand our caste system. It's really a lovely thing. People are very happy about it and so on." I don't think that's quite fair.

True worship doesn't put on a show or make a fuss; true worship isn't forced, isn't half-hearted, doesn't keep looking at its watch, doesn't worry what the person in the next pew is doing. True worship is open to God, adoring God, waiting for God, trusting God even in the dark.
