Catholic Synod on the family

This week the extraordinary Synod on the family called by Pope Francis takes place in Rome. It is a crucial moment for the church because the notion of what constitutes family and attitudes towards things like contraception, marriage, abortion and divorce have changed, putting church teaching out of step with wider society and indeed many Catholics. The question is what should the Church do about it? Pope Francis has hinted he wants change, but of what kind? To what extent is current Church teaching based on scripture and indissoluble, or based on rules that can be reinterpreted and more openly applied?Joining Ernie Rea to discuss the extraordinary Synod on the family are Madeline Teahan, Associate Editor at the Catholic Herald, Paul Vallely author of 'Pope Francis: Untying the Knots' and David Willey the BBC's Vatican Correspondent.Producer: Catherine Earlam.
