Reflections from the Saints

The bread which you use is the bread of the hungry; the garment hanging in your wardrobe is the garment of him who is naked; the shoes you wear are the shoes of the one who is barefoot; the acts of charity that you do not perform are so many injustices that you commit.
– St. Basil the Great
