Since the election of the new Catholic Pope in the Catholic Church a man that comes from Latin America things are probably going to change. People in this region can look at someone who has grew up next to them they can better relate to this person since he came from the region.
South America has always been Catholic leaning and moderately religious, I would say there is a good chance that eventually you could see movements and leaders try to spark a renewal of Catholicism across the land and I could see it spreading like wildfire once it started to take hold.
I believe Latin America will experience a Catholic revival and a big reason is because the Pope is from South America. It is the first time the a Pope is from that part of the world and it is creating a renewed interest in the religion. The Pope hopes this will happen.
That may break people's hearts, but more and more people are coming to terms that religion is just a man made idea. That does not mean people do not believe in God anymore. It just means they are starting to believe in God in their own way. The one thing that is saving the Catholic Church is the new Pope. I think Pope Francis will slow down the trend, but he will not revive the Catholic Church to its earlier Glory.
Although some segments of the Latin American population may fuel a limited Catholic revival, in general secularization and religious diversity will continue to grow. There are simply too many competing schools of thoughts and influences for the Catholic Church to ever approach near the unquestioned supremacy it once had, even if there were to be a revival.
