Quoted from http://www.cnn.com/2017/05/24/politics/pope-trump-homework/index.html:

“Pope Francis also gave the President some homework, or summer reading, if you will: Copies of his three major writings as Pope.
The first, an apostolic exhortation called “The Joy of the Gospel,” may take Trump by surprise. The 50,000-word work, in addition to exhorting the Catholic Church to wake from a spiritual slumber, launches a fierce attack on modern capitalism, blasting the “idolatry of money” and calling trickle-down economics “crude and naive.”

“The culture of prosperity deadens us,” Francis writes in a signature passage. “We are thrilled if the market offers us something new to purchase; and in the meantime all those lives stunted for lack of opportunity seem a mere spectacle; they fail to move us.”…

The Pope’s second written gift to Trump is no easy read, either. In “Laudato Si,” Francis calls for a revolution to halt climate change (which the President has called a Chinese hoax) before the Earth devolves into an “immense pile of filth.”

“What kind of world do we want to leave to those who come after us, to children who are now growing up?” Francis asks.

…The Pope “urges people to put down their smart phones, turn off their televisions and cultivate real relationships.”

“When media and the digital world become omnipresent, their influence can stop people from learning how to live wisely, to think deeply and to love generously,” Francis wrote…”
