Rite Expiatis §22

²² We have seen how the Seraphic Father, motivated by the idea of perfect poverty which had taken complete possession of his soul, made himself so small and humble as to obey others (it would be better to say almost everyone) with the very simplicity of a child, for the reason that he who does not deny himself and give up his own will, certainly cannot be said to have renounced all things or to have become humble of heart. St. Francis by his vow of obedience consecrated gladly and submitted fully his will, the greatest gift which God has bestowed on human nature, to the will of the Vicar of Jesus Christ.
