Saint Robert Bellarmine

Is it not true that You promise those who keep Your commandments a reward more desirable than great wealth and sweeter than honey? You promise a most abundant reward, for as Your apostle James says: "The Lord has prepared a crown of life for those who love Him." What is this crown of life? It is surely a greater good than we can conceive of or desire, as Saint Paul says, quoting Isaiah: "Eye has not seen, ear has not heard, nor has it so much as dawned on man what God has prepared for those who love Him.

Saint Cyprian of Carthage

Let us remember one another in concord and unanimity. Let us on both sides of death always pray for one another. Let us relieve burdens and afflictions by mutual love, that if one of us, by the swiftness of divine condescension, shall go hence the first, our love may continue in the presence of the Lord, and our prayers for our brethren and sisters not cease in the presence of the Father's mercy.

-- Saint Cyprian of Carthage

Saint Catherine of Genoa

The prison in which I seem to myself to be is the world, my chains the body, and it is my soul enlightened by grace which knows the grievousness of being held down or kept back and thus hindered from pursuing its end. This gives my soul great pain for it is very tender. By God's grace it receives a certain dignity which makes it like unto God; nay, rather He lets it share His goodness so that it becomes one with Him. And since it is impossible that God suffer pain, this immunity too befalls the souls who draw near Him; the nearer they come to Him, the more they partake of what is His.  

-- Saint Catherine of Genoa

Saint Ignatius Loyola

If God causes you to suffer much, it is a sign that He has great designs for you, and that He certainly intends to make you a saint. And if you wish to become a great saint, entreat Him yourself to give you much opportunity for suffering; for there is no wood better to kindle the fire of holy love than the wood of the cross, which Christ used for His own great sacrifice of boundless charity.

-- Saint Ignatius Loyola

Saint John Vianney

No, my dear brethren, this gracious virtue of purity is not known to those young men whose eyes and hands are defiled by glances and...Oh God, how many souls does this sin drag down to Hell...This beautiful virtue is not known to those worldly and corrupt girls who make so many preparations and take so many cares to draw the eyes of the world towards themselves, who by their affected and indecent dress announce publicly that they are evil instruments which hell makes use of to ruin souls--those souls which cost so much in labors and tears and torments to Jesus Christ. Look at them, these misfortunates, and you will see that a thousand devils surround their heads and their breasts. An even more astounding thing to understand is how their mothers endure them in a state unworthy of a Christian. I would tell these mothers they are worth no more than their daughters.

-- Saint John Vianney

Saint John de Brébeuf

On receiving the blow of death, I shall accept it from your hands with the fullest delight and joy of spirit. For this reason, my beloved Jesus, and because of the surging joy which moves me, here and now I offer my blood and body and life. May I die only for you, if you will grant me this grace, since you willingly died for me. Let me so live that you may grant me the gift of such a happy death. In this way, my God and Saviour, I will take from your hand the cup of your sufferings and call on your name: Jesus, Jesus, Jesus!

-- Saint John de Brébeuf

Saint Boniface

Let us stand fast in what is right, and prepare our souls for trial. Let us wait upon God's strengthening aid and say to him: "O Lord, you have been our refuge in all generations." 

Let us trust in him who has placed this burden upon us. What we ourselves cannot bear let us bear with the help of Christ. For he is all-powerful, and he tells us: "My yoke is easy, and my burden light." 

Let us continue the fight on the day of the Lord. The days of anguish and of tribulation have overtaken us; if God so wills, "let us die for the holy laws of our fathers," so that we may deserve to obtain an eternal inheritance with them. 

-- Saint Boniface from a letter
