Francis of Assisi. [Letter to Clare of Assisi, 1226] in Leben und Schriften der heiligen Klara von Assisi 274

[Letter from Francis of Assisi to Clare of Assisi]
The text is cited by Clare in her rule, chapter 6.7-9, which deals with poverty. She cites his promise of loving care and solicitude which he fulfilled through his life. Shortly before his death, he sent what she calls his last will, exhorting them never to abandon the life of poverty. To follow his wish, she would have a long struggle with the church hierarchy, as his words seem to foretell.
