189. How do the lay faithful participate in the priestly office of Christ?
They participate in it especially in the Eucharist by offering as a spiritual sacrifice "acceptable to God through Jesus Christ" (1 Peter 2:5) their own lives with all of their works, their prayers, their apostolic undertakings, their family life, their daily work and hardships borne with patience and even their consolations of spirit and body. In this way, even the laity, dedicated to Christ and consecrated by the Holy Spirit, offer to God the world itself.
