‘Wine makes glad the heart of man' (Ps. 104:15). But you who have professed sorrow and grief should turn away from such gladness and rejoice in spiritual gifts. If you rejoice in wine, you will live with shameful thoughts and distress will overwhelm you.
A haughty person is not aware of his faults, or a humble person of his good qualities. An evil ignorance blinds the first, an ignorance pleasing to God blinds the second.
