Pope Francis speaks about the devil frequently in his tweets and homilies.

The pontiff believes that the devil "is not a myth, but a real person," and is "the most insidious enemy of the church," CNN reported. In his homilies, the pope stresses out that people should invite hope in their lives, avoid discouragement, and stay away from negativity and criticism, which the devil offers every single day.

Pope Francis' obsessive mentions of the devil makes him separated from the church's current teachings, which is mum about the demon's vile acts and instead only refers to it in metaphors. With his messages, the pope shares pieces of advice and guidelines on how to overthrow the devil from our lives, CNN wrote.

"The demon is shrewd: he is never cast out forever, this will only happen on the last day," Pope Francis explained, as quoted by the news outlet. "The devil is intelligent, he knows more theology than all the theologians together."

Addressing 600,000 young people in Paraguay on July 12, the pope said that the demon is a "con artist" who makes plenty of promises but "never delivers," CNN added.

"He makes you put your hopes in things which will never make you happy," he further explained, as reported by CNN. "He is a con artist because he tells us that we have to abandon our friends, and never to stand by anyone. (...) He makes you think that your worth depends on how much you possess."

Since his papacy began, Pope Francis has been saying that those who follow Jesus must be alert of the reality of the demon as well. He insists that dialogue, which comes from charity and love, is a necessity in order for people to achieve peace and understand each other, the news outlet explained.

Pope Francis Urges the World to End Poverty

The pope's eight-day visit to Ecuador, Paraguay, and Bolivia emphasized that poor people are often used by rich leaders as a sacrifice to the "altar of money," which costs lives and drives more citizens into impoverished conditions and only benefits the rich and the powerful, Time reported.

In his message, the pope also apologized for the church's lack of action in the matter, Time wrote.

Climate change is also one of the issues that Pope Francis tackled. According to Huffington Post, environmental advocates, Nobel science laureates, global faith leaders, the U.N. leadership, and eco-friendly businesses were sought by the Vatican to promote the pope's message to care for the Earth and humanity.

The pope faults global warming "on an unfair, fossil fuel-based industrial economic model that harms the poor the most," the news outlet wrote. He also believes that grass-roots movements and non-traditional players are the answers when it comes to changing the global system.
