Pope Francis gives an open air mass in Villavicencio, Colombia, on September 8, 2017 during which he will beatify Colombian Bishop Jesus Jaramillo (painting) and priest Petro Maria Ramirez, both murdered by guerrilla groups. Pope Francis urged Colombians to avoid seeking "vengeance" for the sufferings of their country's half-century civil conflict as they work towards a lasting peace. / AFP PHOTO / Alberto PIZZOLI
