In 1968, about 100 to 150 met for a Catholic Pentecostal conference. In 1969, there were about 450 Catholic Charismatics who met including about 25 or 30 priests. In 1970, the increase was more spectacular. Almost 1,300 attended the conference, including Catholics from Canada. In 1974, the Notre Dame conference was attended by 30,000 people.
