We belief that the priest is offering the Mass in persona Christi.
When the priest pronounces the tremendous words of consecration, he reaches up into the heavens, brings Christ down from His throne, and places Him upon our alter to be offered up again as the Victim for the sins of man. It is a power greater than that of monarchs and emperor: it is greater than that of saints and angels, greater than that of Seraphim and Cherubim.
Indeed it is greater even than the power of the Virgin Mary. While the Blessed Virgin was the human agency by which Christ became incarnate a single time, the priest brings Christ down from heaven, and renders Him present on our altar as the eternal Victim for the sins of man – not once but a thousand times! The priest speaks and lo! Christ, the eternal and omnipotent God, bows his head in humble obedience to the priest’s command.
The whole thing is in disregard to the Word.
