Fratelli Tutti §2
Fratelli Tutti: On Fraternity and Social Friendship
2 This saint of fraternal love, simplicity and joy, who inspired me to write the Encyclical Laudato Si’ , prompts me once more to devote this new Encyclical to fraternity and social friendship. Francis felt himself a brother to the sun, the sea and the wind, yet he knew that he was even closer to those of his own flesh. Wherever he went, he sowed seeds of peace and walked alongside the poor, the abandoned, the infirm and the outcast, the least of his brothers and sisters.
