A prayer to St. George:
Blessed St. George, holy martyr and soldier of Christ; through the grace of God almighty you gained victory over the ancient enemy of our fallen race. Help us in our struggle against sin and in our fight for virtue. Under your protection, may we progress in grace and attain for ourselves a crown of glory in heaven. Amen.
