"Catholicism"? Catholicism is Latin America is closer to the "liberation theology" variety, mixed in with Santeria and a whole bunch of other practices like "Curanderismo". It was tolerated by the church for a long time so they could report back to Rome how many new catholics were being brought to the church. If you are a mainstream catholic brought up in the Italian or Irish or Polish tradition of Europe you would not recognize a modern Latin American service, some things will look familiar. The sermon, though sprinkled with mentions of Christ would seem like a Christianized version of Lenin.
Actually Catholicism in South and Latin America is growing to be extremely orthodox.
