The movement was officially approved at Vatican 2 it looks like, and putting Vatican 2 and 2 together-— why it looks like someone noticed how much Pentacostalism was growing in South America, Africa and around the world, and something needed to be done, to compete. The picture is getting clearer.
I think you're on a wild goose chase. The charismatic movement as it is understood by Catholics didn't even exist when VatII was going on. Cardinal Suenens who was one of the architect of the "reforms" of Vatican II later became the de facto patron of the charismatic movement... he was also the patron of Cardinal Danneels (that name shouldn't just ring a bell, it should explode the entire bell tower). He (Suenens) almost singlehandedly destroyed the Catholic Church in Belgium, and I don't mean by turning them all into pentecostals.
Could well be.
Though I think the South American thing mushroomed a significant lapse in time after the birth of the Charismatic Movement.
I could be wrong about that. They might have been more concurrent than I thought.
