Saint Augustine of Hippo

Conquer yourself and the world lies at your feet. 

-- Saint Augustine of Hippo

Saint Monica

Son, as far as I am concerned, nothing in this life now gives me any pleasure. I do not know why I am still here, since I have no further hopes in this world. I did have one reason for wanting to live a little longer: to see you become a Catholic Christian before I died. God has lavished his gifts on me in that respect, for I know that you have even renounced earthly happiness to be his servant. So what am I doing here?

-- Saint Monica to her son Saint Augustine of Hippo

Pope Saint Leo the Great

God decreed that all nations should be saved in Christ. 

-- Pope Saint Leo the Great

Saint Louis IX

Be devout and obedient to our mother the Church of Rome and the Supreme Pontiff as your spiritual father. 

-- Saint Louis IX
