Three quotes from Fr. Stephen Somerville, last living member of original ICEL commission that created the English New Order Mass:
"We found subtle ways of changing the words and dignifying these changes with decent, hopeful, positive expressions,"
"It was a revolution ... we were literally changing the faith of the Catholic Church because we were changing the way it prays."
"Never in the history of the Catholic Church has there been such a revolutionary change in the Mass (and the rest of the Liturgy) as has occurred since the 1960s. Has it been a harmful revolution? Indeed it has! Millions of Catholics have stopped practising their faith in this period, tens of thousands of priests have quit the priesthood, religious orders are dying, and whole new currents of heretical opinion are flowing through the surviving Church."
