CCC 2854 When we ask to be delivered from the Evil One, we pray as well to be freed from all evils, present, past, and future, of which he is the author or instigator. In this final petition, the Church brings before the Father all the distress of the world. Along with deliverance from the evils that overwhelm humanity, she implores the precious gift of peace and the grace of perseverance in expectation of Christ’s return By praying in this way, she anticipates in humility of faith the gathering together of everyone and everything in him who has “the keys of Death and Hades,” who “is and who was and who is to come, the Almighty.”1
Deliver us, Lord, we beseech you, from every evil and grant us peace in our day, so that aided by your mercy we might be ever free from sin and protected from all anxiety, as we await the blessed hope and the coming of our Savior, Jesus Christ.2
