By spiritual exercises…

By the term ‘Spiritual Exercises’ is meant every method of examination of conscience, of meditation, of contemplation, of vocal and mental prayer, and of other spiritual activities… For just as taking a walk, journeying on foot, and running are bodily exercises, so we call Spiritual Exercises every way of preparing and disposing the soul to rid itself of all inordinate attachments, and, after their removal, of seeking and finding the will of God in the disposition of our life for the salvation of our soul.
–Saint Ignatius of Loyola (1491-1556)

Become like Christ…

Let us become like Christ, since Christ became like us.  Let us become God’s for His sake, since He for ours became Man. He assumed the worse that He might give us the better; He became poor that we through His poverty might be rich; He took upon Him the form of a servant that we might receive back our liberty; He came down that we might be exalted; He was tempted that we might conquer; He was dishonored that He might glorify us; He died that He might save us; He ascended that He might draw to Himself us, who were lying low in the Fall of sin. Let us give all, offer all, to Him Who gave Himself a Ransom and a Reconciliation for us.  But one can give nothing like oneself, understanding the Mystery, and becoming for His sake all that He became for ours.
–Saint Gregory Nazianzen (329-c. 391)

Devil is afraid…

The devil is afraid of us when we pray and make sacrifices. He is also afraid when we are humble and good. He is especially afraid when we love Jesus very much. He runs away when we make the Sign of the Cross.
–Saint Anthony of Egypt (c. 251-356)
