The event kicked off a little after 5 pm when the Pope showed up. It's not my best picture of him, but here he is passing my row to get to his chair (just one more row up).
As I said, it was a night of testimonies and performances, and was thoroughly enjoyable. I found the witness talks particularly touching, as people really shared their joys and struggles. The evening concluded with a talk by Pope Francis, in which he encouraged the Synod fathers present to be attentive to the voice of the Holy Spirit as we seek to address the issues presented.
