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.

-- Pope Saint Gregory the Great from a homily

Saint Laurence Ruiz

That I will never do, because I am a Christian, and I shall die for God, and for him I will give many thousands of lives if I had them. And so, do with me as you please.

-- Saint Laurence Ruiz after being asked to renounce his faith

Saint Vincent de Paul

Extend your mercy towards others, so that there can be no one in need whom you meet without helping. For what hope is there for us if God should withdraw His Mercy from us?

-- Saint Vincent de Paul

Saint Marie Victoire Therese Couderc

I abandon myself with my whole heart to God's will, and to God's good pleasure — and when I have in all sincerity made this act of self-surrender, I experience great tranquility and perfect peace. 

-- Saint Marie Victoire Therese Couderc

Saint Cyril of Jerusalem

Only a pure soul can boldly say: "Thy kingdom come." One who has heard Paul say, "Let not sin therefore reign in your mortal bodies," and has purified himself in action thought, and word will say to God: "Thy kingdom come!" 

-- Saint Cyril of Jerusalem

Saint Basil the Great

By the command of your only-begotten Son we communicate with the memory of your saints...by whose prayers and supplications have mercy upon us all, and deliver us for the sake of your holy name. 

-- Saint Basil the Great

Saint Padre Pio of Pietrelcina

Stay with me, Lord, for it is You alone I look for, Your Love, Your Grace, Your Will, Your Heart, Your Spirit, because I love You and ask no other reward but to love You more and more. 

-- Saint Padre Pio of Pietrelcina
