St. Francis' brotherhood included all of God's creation. Much has been written about Francis' love of nature but his relationship was deeper than that. We call someone a lover of nature if they spend their free time in the woods or admire its beauty. Francis really felt that nature, all God's creations, were part of his brotherhood. The sparrow was as much his brother as the pope.
In one famous story, Francis preached to hundreds of birds about being thankful to God for their wonderful clothes, for their independence, and for God's care. The story tells us the birds stood still as he walked among him, only flying off when he said they could leave.
He believed that nature itself was the mirror of God. He called all creatures his “brothers” and “sisters,”. In his “Canticle of the Creatures” (“Praises of Creatures” or “Canticle of the Sun”), he mentioned the “Brother Sun” and “Sister Moon,” the wind and water, and “Sister Death.” He referred to his chronic illnesses as his “sisters." His deep sense of brotherhood under God embraced others, and he declared that “he considered himself no friend of Christ if he did not cherish those for whom Christ died.”
Francis' visit to Egypt and attempted rapprochement with the Muslim world had far-reaching consequences, long past his own death, since after the fall of the Crusader Kingdom, it would be the Franciscans, of all Catholics, who would be allowed to stay on in the Holy Land and be recognized as "Custodians of the Holy Land" on behalf of the Catholic Church.
