Pope Leo XIV encouraged the world to unify around care for the planet as he took the stage at a climate justice conference headlined by actor and former California governor Arnold Schwarzenegger outside of Rome on Wednesday.

“We are one family, with one Father, who makes the sun to rise and sends rain on everyone (Mt 5:45),” Leo said Oct. 1 at a conference center in Castel Gandolfo, Italy. “We inhabit the same planet and must care for it together. I therefore renew my strong appeal for unity around integral ecology and for peace!”

The pontiff and Schwarzenegger addressed the opening day of the Oct. 1–3 “ Raising Hope for Climate Justice ” conference, held at a center near the papal villa of Castel Gandolfo.
