The Second Vatican Council teaches us that the sacred liturgy is the exercise of the priestly office of Jesus Christ. It is the worship of the whole Mystical Body, of Head and members. The many petitions that the word of God and the prayer of the Church place on our lips are part of the sacred liturgy. As baptized members of the Church we are privileged to present these petitions in union with Christ our High Priest. Our petitions have an enormous power and efficacy; they are offered to help all people attain salvation and eternal life.
