Luther and Lewis

Because He tells His Christians to guard against false teachers and thus makes them into judges—yes, gives them power and command to pass sentence on all teachings—He also requires them to be wise and sensible Christians who know what the true teaching is and can distinguish between it and other, false teachings.—Martin Luther, Sermon on Trinity 8, AE 78:293

One rather curious detail [of the Transfiguration observed this day by most Christians] is that this shining or whiteness affected His clothes as much as His body.—C. S. Lewis, Business of Heaven, p. 200.
