But it was with the dramatic outbreak of [the charismatic] movement in the Roman Catholic Church in early 1967 that its unprecedented range became unmistakable. Never before since the division that rent Western Christendom in the sixteenth century had Protestants and Catholics been brought into the same movement of revival and renewal. This was not like getting Catholics and Protestants to have a common service for peace or some other cause of mutual concern. Both were being equally touched by the same unexpected grace. Peopel from both sides were being so grasped by teh Spirit of God that they were all able to worship God together in a way that neither could before.
