Care of the sick is a Corporeal Work of Mercy. Let us pray for all who care for the sick and infirmed, and let us pray for his intervention for when we are care-givers or care-receivers.
Let me start with holy charity, the root of all the virtues and the gift most characteristic of Camillus. He was so fired by this virtue, both towards God and towards his neighbors, especially the sick, that just to see them was enough to melt his tender heart and to make him forget every pleasure, every earthly delight and attachment. Indeed, even when ministering to just one sick man, he seemed to burn himself up and wear himself out with the utmost devotion and compassion. Gladly would he have taken upon himself all their sickness and sufferings to alleviate their pain or take away their weakness.
So vividly did he picture and honor the person of Christ in them that often when distributing food to them he thought of them as his ‘Christs’, and would beg of them grace and the remission of sins. Hence he was as reverent before them as if he were really and truly in the presence of his Lord. Of nothing would he speak more frequently or fervently than of holy charity. He longed that it should take root in the heart of every man.
