The CEO and co-founder of Instagram, Kevin Systrom, was received in a private audience with Pope Francis at the Vatican's Apostolic Palace today.

The Pope and Systrom spoke about the power of images "to overcome cultural, geographic or generational barriers," according to a Vatican source.

Systrom has posted an image of his encounter with the Holy Father in his Instagram profile: "Today I had the honor of meeting Pope Francis. We spoke about the power of images to unite people across different cultures and languages. It was by far one of the most memorable experiences of my life!"
