"A brother or sister"

"IN A WORD, we talk about a man who cannot see the wood for the trees. St. Francis was a man who did not want to see the wood for the trees. He wanted to see each tree as a separate and almost a sacred thing, being a child of God and therefore a brother or sister."

~G.K. Chesterton: St. Francis of Assisi.
