Saint Bede the Venerable (On Saint John the Baptist)

As forerunner of our Lord’s birth, preaching and death, the blessed John showed in his struggle a goodness worthy of the sight of heaven. In the words of Scripture: Though in the sight of men he suffered torments, his hope is full of immortality. We justly commemorate the day of his birth with a joyful celebration, a day which he himself made festive for us through his suffering and which he adorned with the crimson splendour of his own blood. We do rightly revere his memory with joyful hearts, for he stamped with the seal of martyrdom the testimony which he delivered on behalf of our Lord.

-- Saint Bede the Venerable  from a homily on the martyrdom of Saint John the Baptist

Conquer yourself and the world lies at your feet.

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
