Saint Therese of Lisieux

Jesus set the book of nature before me and I saw that all the flowers he has created are lovely. The splendor of the rose and the whiteness of the lily do not rob the little violet of its scent nor the daisy of its simple charm. I realized that if every tiny flower wanted to be a rose, spring would lose its loveliness and there would be no wildflowers to make the meadows gay. It is just the same in the world of souls – which is the garden of Jesus. He has created the great saints who are like the lilies and the roses, but he has also created much lesser saints and they must be content to be the daisies or the violets which rejoice his eyes whenever he glances down. Perfection consists in doing his will, in being that which he wants us to be. Jesus, help me to simplify my life by learning what you want me to be – and becoming that person.

Saint Jerome

The measure of our advancement in the spiritual life should be taken from the progress we make in the virtue of mortification; for it should be held as certain that the greater violence we shall do ourselves in mortification, the greater advance we shall make in perfection. 

-- Saint Jerome

Pope Saint Gregory the Great

You should be aware that the word “angel” denotes a function rather than a nature. Those holy spirits of heaven have indeed always been spirits. They can only be called angels when they deliver some message. Moreover, those who deliver messages of lesser importance are called angels; and those who proclaim messages of supreme importance are called archangels.

Whenever some act of wondrous power must be performed, Michael is sent, so that his action and his name may make it clear that no one can do what God does by his superior power.

-- Pope Saint Gregory the Great from a homily

Saint Augustine of Hippo

Suppose an evil person would offend you, or one whom you judge to be evil or even imagine so. Would you abandon so many others who are good?

-- Saint Augustine of Hippo
