The Apostleship of Prayer announced the intentions chosen by the Pope for October.
His general intention is for "People in despair: That those feeling so crushed by life that they wish to end it may sense the nearness of God's love."
For his mission intention, the Holy Father is praying so "that the celebration of World Mission Day may help all Christians realize that we are not only receivers but proclaimers of God's word."
World Mission Day is celebrated this year on Oct. 20. Here is the Pope's message for the day: http://www.vatican.va/holy_father/francesco/messages/missions/documents/papa-francesco_20130519_giornata-missionaria2013_en.html
