Venerable Archbishop Fulton Sheen

The denial of personal guilt makes men ready to surrender their liberty. Better it is for a man to realize he has evil tendencies which must be fought and combated in order that his higher self may emerge.

-- Venerable Archbishop Fulton Sheen

Pope Saint Clement I of Rome On Martyrs of Rome

To these men who spent their lives in the practice of holiness, there is to be added a great multitude of the elect, who, having through envy endured many indignities and tortures, furnished. us with a most excellent example. Through envy, those women, the Danaids and Dircae, being persecuted, after they had suffered terrible and unspeakable torments, finished the course of their faith with stedfastness, and though weak in body, received a noble reward. Envy has alienated wives from their husbands, and changed that saying of our father Adam, "This is now bone of my bones, and flesh of my flesh." Envy and strife have overthrown great cities and rooted up mighty nations.

These things, beloved, we write unto you, not merely to admonish you of your duty, but also to remind ourselves. For we are struggling on the same arena, and the same conflict is assigned to both of us. Wherefore let us give up vain and fruitless cares, and approach to the glorious and venerable rule of our holy calling. Let us attend to what is good, pleasing, and acceptable in the sight of Him who formed us. Let us look steadfastly to the blood of Christ, and see how precious that blood is to God, which, having been shed for our salvation, has set the grace of repentance before the whole world. 

-- Pope Saint Clement I of Rome from The First Epistle of Clement to the Corinthians

Pope Saint Clement I of Rome On Saints Peter and Paul

Let us take the noble examples of our own generation. It was due to jealousy and envy that the greatest and most holy pillars were persecuted and fought to the death. Let us pass in review the good Apostles: a Peter, who through unmerited jealousy underwent not one or two, but many hardships and, after thus giving testimony, departed for the place of glory that was his due. Through jealousy and strife Paul demonstrated how to win the prize of patient endurance: seven times he was imprisoned; he was forced to leave and stoned; he preached in the East and the West; and, finally, he won the splendid renown which his faith had earned. He taught the right manner of life to the whole world, traveled as far as the Western boundary, and, when he had given testimony before the authorities, ended his earthly career and was taken up into the holy place as the greatest model of patient endurance.

-- Pope Saint Clement I of Rome from The First Epistle of Clement to the Corinthians

Saint Irenaeus of Lyons

The glory of God gives life; those who see God receive life. Men will therefore see God if they are to live; through the vision of God they become immortal and attain to God himself. God is the source of all activity throughout creation. He cannot be seen or described in his own nature and in all his greatness by any of his creatures. Yet he is certainly not unknown. Through his Word the whole creation learns that there is one God the Father, who holds all things together and gives them their being. As it is written in the Gospel, “No man has ever seen God, except the only-begotten Son, who is in the bosom of the Father; he has revealed him.” From the beginning the Son is the one who teacher us about the Father; he is with the Father from the beginning. The Word revealed God to men and presented men to God. Life in man is the glory of God; the life of man is the vision of God. If the revelation of God through creation gives life to all who live upon the earth, much more does the manifestation of the Father through the Word give life to those who see God.

-- Saint Irenaeus of Lyons from "Against the Heresies"

Saint Cyril of Alexandria

The divinely inspired Scriptures affirm that the Word of God was made flesh, that is to say, he was united to a human body endowed with a rational soul. He undertook to help the descendants of Abraham, fashioning a body for himself from a woman and sharing our flesh and blood, to enable us to see in him not only God, but also, by reason of this union, a man like ourselves. It is held, therefore, that there is in Emmanuel two entities, divinity and humanity. Yet our Lord Jesus Christ is nonetheless one, the one true Son, both God and man; not a defied man on the same footing as those who share the divine nature by grace, but true God who for our sake appeared in human form. We are assured of this by Saint Paul’s declaration: “When the fullness of time came, God sent his Son, born of a woman, born under the law, to redeem those who were under the law and to enable us to be adopted as sons.

-- Saint Cyril of Alexandria from a letter

Saint Josemaria Escriva de Balaguer

Jesus suffers to carry out the will of the Father. And you, who also want to carry out the most holy Will of God, following the steps of the Master, can you complain if you meet suffering on your way?

-- Saint Josemaria Escriva de Balaguer

Saint Francis Xavier

I wish the university students would work as hard at converting these people as they do at their books, and so settle their account with God for their learning and the talents entrusted to them. 

This thought would certainly stir most of them to meditate on spiritual realities, to listen actively to what God is saying to them. They would forget their own desires, their human affairs, and give themselves over entirely to God's will and his choice. 

They would cry out with all their heart: "Lord, I am here! What do you want me to do?" Send me anywhere you like - even to India!"

-- Saint Francis Xavier in a letter to Saint Ignatius Loyola
