Kyrie Eleison. God, our Lord, King of ages, All-powerful and All-mighty, you who made everything and who transformed everything simply by your will. You who in babylon changed into dew the flames of the 'seven-times hotter' furnace and protected and saved the three holy children. You are the doctor and the physician of our soul. You are the salvation of those who turn to you. We beseech you to make powerless, banish, and drive out every diabolical power, presence, and machination; every evil influence, malefice, or evil eye and all evil actions aimed against your servant...where there is envy and malice, give us an abundance of goodness, endurance, victory, and charity. O Lord, you who love man, we beg you to reach out your powerful hands and your most high and mighty arms and come to our aid. Help us, who are made in your image; send the angel of peace over us, to protect us body and soul. May he keep at bay and vanquish every evil power, every poison or malice invoked against us by corrupt and envious people. Then under the protection of your authority may we sing, in gratitude, "The Lord is my salvation; whom should I fear? I will not fear evil because you are with me, my God, my strength, my powerful Lord, Lord of peace, Father of all ages. Yes, Lord our God, be merciful to us, your image, and save your servant (name the person), from every threat or harm from the evil one, and protect him by raising him above all evil. We ask you this through the intercession of our Most Blessed, Glorious Lady, Mary ever Virgin, Mother of God, of the most splendid archangels and all your saints. Amen! From the Greek Ritual "ANIMA CHRISTI

" Soul of Christ, sanctify me; Body of Christ, save me; Blood of Christ, inebriate me; Water from the side of Christ, wash me; Passion of Christ, strengthen me; 
O good Jesus, hear me; within Your wounds, hide me; let me never be separated from You; from the evil one, protect me; at the hour of my death, call me; and bid me come to You; that with Your saints, I may praise You forever and ever. Amen. IOTT
