“In the Lord’s Prayer a petition is made for daily bread, which for Christians mean principally the Eucharistic Bread, and entreating also purification from sin, so that what is holy may in truth be given to the holy. The Priest pronounces the invitation  to the prayer, and all the faithful say the prayer with him; then the Priest alone adds the embolism, which the people conclude by means of the doxology. The embolism, developing the last petition of the Lord’s Prayer itself, asks for deliverance from the power of evil for the whole community of the faithful.”                                                                                                        - GIRM #81
