CCC 1109 The epiclesis is also a prayer for the full effect of the assembly’s communion with the mystery of Christ. “The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit”1 have to remain with us always and bear fruit beyond the Eucharistic celebration. The Church therefore asks the Father to send the Holy Spirit to make the lives of the faithful a living sacrifice to God by their spiritual transformation into the image of Christ, by concern for the Church’s unity, and by taking part in her mission through the witness and service of charity.
1 2 Cor 13:13.
