A moment ago, just before the Lavabo, we invoked the Holy Spirit, asking him to bless the sacrifice offered to his holy name. After washing his hands, the priest, in the name of all those present, prays to the Holy Trinity — Suscipe, Sancta Trinitas — to accept our offering in memory of the life of Christ and of his passion, resurrection and ascension; and in honour of Mary, ever Virgin, and of all the saints.
May this offering be effective for the salvation of all men — Orate, fratres, the priest invites the people to pray — because this sacrifice is yours and mine, it is the sacrifice of the whole Church. Pray, brethren, although there may not be many present, although materially there may be only one person there, although the celebrant may find himself alone; because every Mass is a universal sacrifice, the redemption of every tribe and tongue and people and nation.
Through the communion of the saints, all Christians receive grace from every Mass that is celebrated, regardless of whether there is an attendance of thousands of persons, or whether it is only a boy with his mind on other things who is there to serve. In either case, heaven and earth join with the angels of the Lord to sing: Sanctus, Sanctus, Sanctus... (Christ is passing by, 89)
