Pope Francis on Friday issued a warning against the rise of fascist forces worldwide that remind him of the Nazis of the 20th Century as he also railed against corporate crimes and announced consideration of adding “sins against ecology” to the church’s official teachings.

During a speech at the Vatican before the 20th World Congress of the International Association of Penal Law, a network of justice system and criminology experts from around the world, the leader of the Catholic Church said worrying developments both in the political arena and from the world of business remind him of dark episodes from humanity’s past, including Adolf Hitler’s Third Reich.

“It is not coincidental that at times there is a resurgence of symbols typical of Nazism,” Francis said as he decried the “culture of waste and hate” represented by contemporary politicians who spew derogatory and racists attacks against homosexuals, gypsies, Jewish people, and others. “I must confess to you,” he continued, “that when I hear a speech (by) someone responsible for order or for a government, I think of speeches by Hitler in 1934, 1936.”

The Pope also highlighted environmental degradation and said the church was considering adding crimes against nature and the environment to the catechism—the official text of church doctrine and teachings.

“We have to introduce, we are thinking about it, in the catechism of the Catholic Church, the sin against ecology, the sin against our common home, because it’s a duty,” he said. Francis has been championed by climate activists for using his position to preach about the urgent need for humanity to recognize the dangers of human-caused global warming and calling on other world leaders—and the estimated 1.2 billion Catholics in the world—to act boldly to address the crisis . . .
