His visit follows three days of violence in the capital, Santiago, over claims of abuses by the Catholic Church.
Over the weekend, three Roman Catholic churches were firebombed and a note was left at the scene threatening the pontiff.
Pope Francis will later travel to Peru.
Illari Aragon, Catholic Agency For Overseas Development's (CAFOD) programme office for Peru, told Premier how influential the pontiff is in the country.
She explained: "In Peru everyone was a bit surprised that Pope Francis decided to visit this... problematic region of Peru that, on one hand, is really beautiful and is full of biodiversity and ecological wealth.
"But on the other hand, it's been devastated."
The pontiff has told reporters on board the plane for his trip to Chile that the world is one step away from nuclear war.
His comments came after Hawaii issued a false missile alert that provoked panic in the US state and highlighted the risk of an "accidental nuclear war" with North Korea, a point made in the Pope's "state of the world" speech.
Aragon told Premier how important his presence in the countries will be.
She said: "I do think that his visit there has a point and I do think that his message is about protection, it's about hope for the people suffering in this region and [to make us] all think about that."
