The Sisters by Frank Stone English

"O hope, sweet sister of faith, you are that virtue which with the keys of the Blood of Christ unlock eternal life to us.  You guard the city of the soul against the enemy of confusion, and when the devil tries to cast the soul into despair by pointing out the seriousness of its past sins, you do not slacken your pace, but full of energy, you persevere in fortitude, putting on the balance the price of Christ's Blood.  You place on the brow of perseverance the crown of victory, for you have hoped to obtain it by the power of His Blood."
St. Catherine of Siena.
