Saint Augustine of Hippo

Whoever, then, loves his neighbor aright, ought to urge upon him that he too should love God with his whole heart, and soul, and mind. For in this way, loving his neighbor as himself, a man turns the whole current of his love both for himself and his neighbor into the channel of the love of God, which suffers no stream to be drawn off from itself by whose diversion its own volume would be diminished. 

-- Saint Augustine of Hippo

Saint Serapion the Scholastic

The mind is purified by spiritual knowledge (or by holy meditation and prayer), the spiritual passions of the soul by charity, and the irregular appetites by abstinence and penance.

-- Saint Serapion the Scholastic

Saint Vincent Pallotti

You must be holy in the way that God asks you to be holy. God does not ask you to be a Trappist monk or a hermit. He wills that you sanctify the world and your everyday life. 

-- Saint Vincent Pallotti

Saint Bernadine of Siena On Saint Joseph

There is a general rule concerning all special graces granted to any human being. Whenever the divine favor chooses someone to receive a special grace, or to accept a lofty vocation, God adorns the person chosen with all the gifts of the Spirit needed to fulfill the task at hand. This general rule is especially verified in the case of Saint Joseph, the foster-father of our Lord, and the husband of the Queen of our world, enthroned above the angels. He was chosen by the eternal Father as the trustworthy guardian and protector of his greatest treasures, namely, his divine Son and Mary, Joseph’s wife. He carried out this vocation with complete fidelity until at last God called him, saying “Good and faithful servant, enter into the joy of your Lord.” Remember us, Saint Joseph, and plead for us to your foster child. Ask your most holy bride, the Virgin Mary, to look kindly upon us, since she is the mother of him who with the Father and the Holy Spirit lives and reigns eternally. Amen.

-- Saint Bernardine of Siena from a sermon

Saint Cyril of Jerusalem

It is not only among us, who are marked with the name of Christ, that the dignity of faith is great; all the business of the world, even of those outside the Church, is accomplished by faith. By faith, marriage laws join in union persons who were strangers to one another. By faith, agriculture is sustained; for a man does not endure the toil involved unless he believes he will reap a harvest. By faith, seafaring men, entrusting themselves to a tiny wooden craft, exchange the solid element of the land for the unstable motion of the waves. Not only among us does this hold true but also, as I have said, among those outside the fold. For though they do not accept the Scriptures but advance certain doctrines of their own, yet even these they receive on faith. 

-- Saint Cyril of Jerusalem

Saint John of Avila

Withdraw your heart from the world before God takes your body from it.

-- Saint John of Avila

Saint John of the Cross

O you souls who wish to go on with so much safety and consolation, if you knew how pleasing to God is suffering, and how much it helps in acquiring other good things, you would never seek consolation in anything; but you would rather look upon it as a great happiness to bear the Cross of the Lord. 

-- Saint John of the Cross
