Dilexit Nos §27
Dilexit Nos: On the Human and Divine Love of the Heart of Jesus Christ
27 Before the heart of Jesus, living and present, our mind, enlightened by the Spirit, grows in the understanding of his words and our will is moved to put them into practice. This could easily remain on the level of a kind of self-reliant moralism. Hearing and tasting the Lord, and paying him due honour, however, is a matter of the heart. Only the heart is capable of setting our other powers and passions, and our entire person, in a stance of reverence and loving obedience before the Lord.
