Pope Francis (R) smiles as he arrives for his speech at the Synod on the Families, to cardinals and bishops gathering in the Synod Aula, at the Vatican, on October 6, 2014. Pontiff on Sunday launched a major review of Catholic teaching on the family that could lead to change in the Church's attitude to marriage, cohabitation and divorce. An extraordinary synod, or meeting, of nearly 200 bishops from around the world and a sprinkling of lay people will, for the next two weeks, address the huge gulf between what the Church currently says on these issues and what tens of millions of believers actually do.
