He wrote, “In antiquity, missa simply meant ‘dismissal.’ However in Christian usage it gradually took on a deeper meaning. The word ‘dismissal’ has come to imply a ‘mission.’ These few words succinctly express the missionary nature of the Church. The People of God might be helped to understand more clearly this essential dimension of the Church’s life, taking the dismissal as a starting- point.” Instead of seeing the words of the priest or deacon as a conclusion to the celebration, Pope Benedict saw them as a beginning. He made that abundantly clear when he developed new words for the dismissal at Mass. Pope Benedict approved the phrases, “Ite ad Evangelium Domini annuntiandum (Go and announce the Gospel of the Lord)” and “Ite in pace, glorificando vita vestra Dominum (Go in peace, glorifying the Lord by your life).” Both of these dismissals focus on the missionary character of the Mass and how those in the pew are meant to go out in the world, sustained by the Eucharist they just received. Viewed in this framework, the “Mass” is not just a single celebration on a Sunday or weekday or feast day, but a starting-point for a lifelong journey of Christian witness. The priest, in the place of Christ, sends forth his parishioners into the world so that they may be beacons of light, set on a hill for all to see.
