Saint Martin de Porres

Forgive my error, and please instruct me, for I did not know that the precept of obedience took precedence over that of charity.

-- Saint Martin de Porres to his superior after being reprimanded for taking an injured Indian to his room.

Saint Theresa of Avila

The devil will try to upset you by accusing you of being unworthy of the blessings that you have received. Simply remain cheerful and do your best to ignore the devil's nagging. If need be even laugh at the absurdity of the situation. Satan, the epitome of sin itself, accuses you of unworthiness! When the devil reminds you of your past, remind him of his future!

-- Saint Theresa of Avila

Saint Augustine of Hippo

Neither are the souls of the pious dead separated from the Church which even now is the kingdom of Christ. Otherwise there would be no remembrance of them at the altar of God in the communication of the Body of Christ.

-- Saint Augustine of Hippo from "The City of God"

Saint Thomas More

And, therefore, my own good daughter, do not let your mind be troubled over anything that shall happen to me in this world. Nothing can come but what God wills. And I am very sure that whatever that be, however bad it may seem, it shall indeed be the best. 

-- Saint Thomas More in a letter from prison to his daughter Margaret

Saint John of the Cross

Live in the world as if only God and your soul were in it; then your heart will never be made captive by any earthly thing. 

-- Saint John of the Cross

Saint Gregory Nazianzen

Nothing gives such pleasure to God as the conversion and salvation of men, for whom his every word and every revelation exist. He wants you to become a living force for all mankind, lights shining in the world. You are to be radiant lights as you stand beside Christ, the great light, bathed in the glory of him who is the light of heaven. 

--Saint Gregory Nazianzen

Saint Jude Thaddeus

To the one who is able to keep you from stumbling and to present you unblemished and exultant, in the presence of His Glory, to the only God, Our Savior, through Jesus Christ Our Lord be glory, majesty, power, and authority from ages past, now, and for ages to come. Amen

-- Saint Jude Thaddeus from The Epistle of Jude 1:24-25
