Here's a video of Pope Francis' address before the Angelus this Sunday. I add a simultaneous translation into English. He talks about how we, as Christians, need to be light of the world and salt of the earth. He asks the crowd several times whether they want to be a lamp that is lit and burning, or an extinguished lamp. They answer back, "a lit lamp!"
May God bless our Holy Father, and may He also bless you!
