According to the CONSTITUTION ON THE SACRED LITURGY SACROSANCTUM CONCILIUM SOLEMNLY PROMULGATED BY HIS HOLINESS POPE PAUL VI ON DECEMBER 4, 1963, “… the prayers addressed to God by the priest who presides over the assembly in the person of Christ are said in the name of the entire holy people and of all present. And the visible signs used by the liturgy to signify invisible divine things have been chosen by Christ or the Church. Thus not only when things are read “which were written for our instruction” (Rom. 15:4), but also when the Church prays or sings or acts, the faith of those taking part is nourished and their minds are raised to God, so that they may offer Him their rational service and more abundantly receive His grace.” See http://www.ewtn.com/library/councils/v2litur.htm
