Vatican City, Aug 21, 2014 / 02:07 pm (CNA/EWTN News).- “Slaves no more, but brothers and sisters” is the title of the message Pope Francis will deliver for the 2015 World Day of Peace, the Pontifical Council for Justice and Peace stated Thursday.

“Slavery is a terrible open wound on the contemporary social body, a fatal running sore on the flesh of Christ,” the pontifical council said in an Aug. 21 statement.
