Ministries in Liturgy
The vocation of lay people
"By reason of their special vocation it belongs to the laity to seek the kingdom of God by engaging in temporal affairs and directing them according to God's will. . . . It pertains to them in a special way so to illuminate and order all temporal things with which they are closely associated that these may always be effected and grow according to Christ and maybe to the glory of the Creator and Redeemer."
~ LG 31 § 2.
The participation of lay people in Christ's priestly office
"Hence the laity, dedicated as they are to Christ and anointed by the Holy Spirit, are marvelously called and prepared so that even richer fruits of the Spirit maybe produced in them. For all their works, prayers, and apostolic undertakings, family and married life, daily work, relaxation of mind and body, if they are accomplished in the Spirit - indeed even the hardships of life if patiently born - all these become spiritual sacrifices acceptable to God through Jesus Christ. In the celebration of the Eucharist these may most fittingly be offered to the Father along with the body of the Lord. And so, worshiping everywhere by their holy actions, the laity consecrate the world itself to God, everywhere offering worship by the holiness of their lives."
~ LG 34; cf. LG 10, 1 Pet 2:5.
