In my admittedly small mind there is really only one question about the validity of the Reformation of the Western Church:
Are God’s commands, threats, and punishments – His Hammer which shatters – to be proclaimed so that persons may see themselves as sinners – sinners who should then be given the confidence of faith – i.e. be actively persuaded via the Promise (Christ) that they have God’s forgiveness for all their sins (and hence, life and salvation) – even as they tremble?
Is this to continually occur in the life of the Christian, until death comes, or not? Is this pattern of “Law and Gospel” to be that which the heralds of God’s Word bring – or not? This, in my mind, is *the* question for the Church posed by the Reformation – and everything else flows from this.
