Therefore the whole perpetual sacrificial offering of Christ at the cross, in the holy Mass, and in the eternal glory of heaven can be conceived as a single great thanksgiving as Eucharist: as gratitude for creation, salvation, and consummation. Christ presents himself in the name of all creation, whose prototype he is and to which he descended to renew it from the inside out and lead it to perfection. But he also calls upon the entire created world itself, united with him, to give the Creator the tribute of thanks that is his due.
