" The “purity” to which the Apostle Peter is referring means not submitting to these standards, not seeking applause, but rather, seeking obedience to the truth. And I think that this is the fundamental virtue for the theologian, this discipline of obedience to the truth, which makes us, although it may be hard, collaborators of the truth, mouthpieces of truth, for it is not we who speak in today’s river of words, but it is the truth which speaks in us, who are really purified and made chaste by obedience to the truth. So it is that we can truly be harbingers of the truth. "
