From the Orthodox Prayer Book--
Evening Prayer to the Holy Guardian Angel
O Angel of Christ, my holy Guardian and Protector of my soul and body, forgive me all my sins of today. Deliver me from all the wiles o the enemy, that I may not anger my God by any sin. Pray for me, sinful and unworthy servant, that thou mayest present me worthy of the kindness and mercy of the All-holy Trinity and the Mother of my Lord Jesus Christ, and of all the Saints. Amen
Rest in God, seek repose. For those for whom this was a day of leisure, how did we meet Christ in our leisure? What did we say to Him to thank Him for the goodness of this world and this life? How did we let Him know that we were content to rest in Him?
For those for whom this was another day of work: How will we meet Christ in our leisure? How will we make every moment a powerful moment of prayer and of love? How will we turn our leisure time into time for Christ and for sharing Jesus with all the world?
Steven,
Thank you for posting this prayer. As I move closer and closer to actual communion in the Orthodox Church, such prayers, with the whole assembly at night (in this case, the whole assembly is the priest, the deacon, and little ol' me), give real grace when the day is daunting.
Peace.
