Saint John Mary Vianney

Prayer is nothing else but union with God. In this intimate union, God and the soul are fused together like two bits of wax that no one can ever pull apart. This union of God with a tiny creature is a lovely thing. It is a happiness beyond understanding. 

-- Saint John Mary Vianney

Pope Saint Gregory the Great

As for certain lesser faults, we must believe that, before the Final Judgment, there is a purifying fire. He who is truth says that whoever utters blasphemy against the Holy Spirit will be pardoned neither in this age nor in the age to come. From this sentence we understand that certain offenses can be forgiven in this age, but certain others in the age to come.

-- Pope Saint Gregory the Great

Saint Peter Julian Eymund

If the love of Jesus in the Most Blessed Sacrament does not win our hearts, Jesus is vanquished! Our ingratitude is greater than His Goodness our malice is more powerful than His Charity. 

-- Saint Peter Julian Eymund 

Saint Alphonsus Liguori

When we hear people talk of riches, honors and amusements of the world, let us remember that all things have an end, and let us then say: "My God, I wish for You alone and nothing more." 

-- Saint Alphonsus Liguori

Saint Ignatius of Loyola

Do not let any occasion of gaining merit pass without taking care to draw some spiritual profit from it; as, for example, from a sharp word which someone may say to you; from an act of obedience imposed against your will; from an opportunity which may occur to humble yourself, or to practice charity, sweetness, and patience. All of these occasions are gain for you, and you should seek to procure them; and at the close of that day, when the greatest number of them have come to you, you should go to rest most cheerful and pleased, as the merchant does on the day when he had had most chance for making money; for on that day business has prospered with him. 

-- Saint Ignatius of  Loyola

Saint Peter Chrysologus

Anyone who wishes to frolic with the devil cannot rejoice with Christ. 

-- Saint Peter Chrysologus

Saint Augustine of Hippo

No one of you should say, "Blessed are they who have deserved to receive Christ into their homes!" Do not grieve or complain that you were born in a time when you can no longer see God in the flesh. He did not in fact take this privilege from you. As he says, "Whatever you have done to the least of my brothers, you did to me." 

-- Saint Augustine of Hippo
