Saint Mark the Ascetic

Even though knowledge is true, it is still not firmly established if unaccompanied by works. For everything is established by being put into practice. 

-- Saint Mark the Ascetic

Saint Teresa of Avila

If Christ Jesus dwells in a man as his friend and noble leader, that man can endure all things, for Christ helps and strengthens us and never abandons us. He is a true friend. And I clearly see that if we expect to please him and receive an abundance of his graces, God desires that these graces must come to us from the hands of Christ, through his most sacred humanity, in which God takes delight. 

-- Saint Teresa of Avila 

Saint Katharine Drexel

It is a lesson we all need – to let alone the things that do not concern us.  He has other ways for others to follow Him; all do not go by the same path.  It is for each of us to learn the path by which He requires us to follow Him,  and to follow Him in that path.  

-- Saint Katharine Drexel

Saint Bernard of Clairvaux

Inordinate love for the flesh is cruelty, because under the appearance of pleasing the body, we kill the soul.

-- Saint Bernard of Clairvaux
