“A Prayer for Purity Through the Intercession of St. Augustine” is a Catholic prayer that turns to our beloved St. Augustine, who battled lust and impurity firsthand. Before his conversion, he spent years chasing worldly pleasure, famously admitting to God, “Grant me chastity, but not yet.” That candid struggle, followed by his complete transformation through grace, is what makes him a natural intercessor for anyone fighting the same battle today.
This prayer asks him to intercede before the Lord for freedom from lust and impurity, for a mind renewed and a heart guarded against temptation, and for the courage to answer God’s call without delay. It closes by placing that plea directly before Christ, echoing the humble cry of the publican: Lord Jesus, have mercy on me, a sinner.
A Prayer For Purity Through the Intercession of St. Augustine
O St. Augustine, you who once wandered far into sin and knew the heavy chains of lust before Christ set you free, hear my prayer.
You cried out to God, “Grant me chastity, but not yet,” and yet in His mercy, the Lord did not abandon you to that delay. He broke the hold of disordered desire upon your heart and gave you the strength to live in purity and truth.
I come to you now, weighed down by the same struggle. Intercede for me before the Lord, that I may be freed from the grip of lust and impurity. Ask our Savior to renew my mind, to guard my eyes and my heart, and to give me the courage to turn away from sin before it takes deeper root.
You know how hard the fight can be, and you know the joy that waits on the other side of it. Pray that I may not delay in answering God’s call, but surrender fully to His grace today.
Through your intercession, may I walk in purity, and may my heart find the rest it was made for in God alone. Amen.
Lord Jesus, have mercy on me, a sinner.
