What do we mean by living in harmony with the earth? Does it mean that you never kill, that you live in a log cabin, that you don’t reproduce, that you own nothing? Of course it doesn’t. In practice, what it means is that each of us keeps trying (in our own ways and at our own pace) to lessen our impact upon the earth and its life.
When someone steals another’s clothes, we call him a thief. Should we not give the same name to one who could clothe the naked and does not? The bread in your cupboard belongs to the hungry; the coat hanging unused in your closet belongs to the one who needs it; the shoes rotting in your closet belong to the one who has no shoes; the money which you hoard up belongs to the poor.
Basil the Great
