CHICAGO —  The Archdiocese of Chicago has condemned today’s attacks in Orlando, Florida, and praised the heroic efforts of first responders.

Early Sunday, Omar Mateen, 29, walked into Pulse, a gay nightclub in Orlando, and opened fire, killing at least 50 people and wounding more than 50 others. In a statement Sunday, Archbishop Blase Cupich said the world must meet violence with peace, and intolerance with tolerance.

Cupich said in the statement:

Our prayers and hearts are with the victims of the mass shooting in Orlando, their families and our gay and lesbian brothers and sisters.

We are grateful to the first responders and civilians who heroically put themselves in harm’s way, providing an enduring reminder of what compassion and bravery look like–even in the face of such horror and danger.

In response to hatred, we are called to sow love. In response to violence, peace. And, in response to intolerance, tolerance.

The people of the Archdiocese of Chicago stand with the victims and their loved ones, and reaffirm our commitment, with Pope Francis, to address the causes of such tragedy, including easy access to deadly weapons. We can no longer stand by and do nothing.
