Through the intellect, beholder of the light of divine life, we receive knowledge of God’s hidden mysteries. Through the soul’s faculty of judgment we winnow in the light of this knowledge the thoughts that arise within the heart, distinguishing the good from the bad.
Through the discrimination of the intelligence we savor our conceptual images. Those that spring from a bitter root we transform into sweet nourishment for the soul, or else we reject them entirely; those that spring from a virtuous and vigorous stock we accept. In this way we take every thought captive and make it obey Christ (2 Corinthians 10:5).
Through the understanding of the intellect we smell the spiritual unguent of the grace of the Holy Spirit, our hearts filled with joy and gladness. Through the watchfulness of the heart we consciously perceive the Spirit, who refreshes the flame of our desire for supernal blessings and warms our spiritual powers, numbed as they have been by the frost of the passions.
