St. Caesarius of Arles has some thoughts on mercy in today’s readings:
There is earthly and heavenly mercy: that is, human and divine. What is human mercy? Exactly this: to have care for the sufferings of the poor. What is divine mercy? Without doubt, to grant forgiveness of sins.
Whatever human mercy gives away on the journey, divine mercy pays back when we arrive at last in our native land. For it is God who feels cold and hunger, in the person of the poor. As he himself has said: As much as you have done for the least of these, you have done it for me.
What God deigns to give on heaven, he yearns to receive on earth.
