'...the existence of such a gathering is wholly astonishing. It is grounded in no human possibility; indeed, from the side of human history it is nothing other than a sheer impossibility, for the commonwealth of human time lies under the sway of sin and alienation, striving with all its might to oppose God and to refuse his call to reconciliation...That such a holy people exists and is preserved through time, that it does not collapse back into alienantion and hatred, that here sin is held in check and not permitted to eat away at human fellowship - all this lies in the hands of the holy God alone.'
John Webster. Holiness, p.57.
