Bede the Venerable — as excerpted in the Catena Aurea on Mark 2:1-12

“Or else, because there are four virtues, by which a man is through an assured heart exalted so that he merits safety; which virtues some call prudence, fortitude, temperance, and justice. Again, they desire to bring the palsied man to Christ, but they are impeded on every side by the crowd which is between them, because often the soul desires to be renewed by the medicine of Divine grace, but through the sluggishness of the grovelling body is held back by the hindrance of old custom. Oftentimes amidst the very sweetnesses of secret prayer, and, as it may be called, the pleasant converse with God, a crowd of thoughts, cutting off the clear vision of the mind, shuts out Christ from its sight. Let us not then remain in the lowest ground, where the crowds are bustling, but aim at the roof of the house, that is, the sublimity of the Holy Scripture, and meditate on the law of the Lord.”
