"What deserves to be called mysticism—not in the vague sense of the history and philosophy of religion, but rather in the Catholic-ecclesial sense—occurs when God's Word is heard, not only with exegetical and theological understanding, but with the whole heart, the whole being, when one is steadfast before the self-disclosure of the heart of God despite fire and night."
