A painting of Colombian priest Petro Maria Ramirez, who will be beatified by Pope Francis along with Bishop Jesus Jaramillo, both murdered by guerrilla groups, is seen during an open air mass given by the pontiff in Villavicencio, Colombia, on September 8, 2017. 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
