Here is a ZENIT translation of the letter Pope Francis sent to the Olympic team formed by refugees.
July 26, 2016
To the members of the Olympic team of refugees,
Dear brothers and sisters Rami Anis, Yiech Pur Biel, James Nyang Chiengjiek, Yonas Kinde, Anjelina Nada Lohalith, Rose Nathike Lokonyen, Paulo Amotun Lokoro, Yusra Mardini, Popole Misenga and Yolande Bukasa Mabika:
I send you my greetings and my best wishes for success during the Olympics. May the courage and valor that you have within you express, through the Olympic games, a cry for fraternity and peace. May humanity, through you, come to understand that peace is possible, that everything is won with peace. And that everything is lost with war.
May your testimony benefit us all. I pray for you, and please, I ask you to pray for me.
