In his speech before Congress on Thursday, Pope Francis call on the world to combat violence and extremism, noting that every religion is susceptible to pockets of fundamentalism.

“Our world is increasingly a place of violent conflict, hatred and brutal atrocities, committed even in the name of God and of religion. We know that no religion is immune from forms of individual delusion or ideological extremism. This means that we must be especially attentive to every type of fundamentalism, whether religious or of any other kind,” he said.

The pope noted that when working to combat extremism, people must not view the conflict through a black and white lens and must protect religious freedom.

“A delicate balance is required to combat violence perpetrated in the name of a religion, an ideology or an economic system, while also safeguarding religious freedom, intellectual freedom and individual freedoms. But there is another temptation which we must especially guard against: the simplistic reductionism which sees only good or evil; or, if you will, the righteous and sinners,” Pope Francis said. “The contemporary world, with its open wounds which affect so many of our brothers and sisters, demands that we confront every form of polarization which would divide it into these two camps.”

He called on people not to take on the anger of extremists.

“We know that in the attempt to be freed of the enemy without, we can be tempted to feed the enemy within. To imitate the hatred and violence of tyrants and murderers is the best way to take their place. That is something which you, as a people, reject,” he said.
