Pope Francis arrives for a vigil in St. Peter's Square at the Vatican, Saturday, Oct. 4, 2014. Pope Francis on Sunday opens a two-week meeting of bishops and cardinals from around the world aimed at making the church's teaching on family life, marriage, sex, contraception, divorce and homosexuality, relevant to today's Catholic families. The pre-synod debate has been dominated by mudslinging between liberals and conservatives over divorce and remarriage, but there are many more issues up for discussion.
