O Almighty and Eternal God, who savest all, and willest not that any should perish, look, we beseech Thee, upon the souls that are led astray by the deceits of the devil; that, rejecting all errors, the hearts of those who err may be converted, and return to the unity of Thy truth. Through Christ our Lord. Amen.
