Pope Francis is sending the next World Meeting of Families to Dublin in 2018. It is the largest Catholic gathering of families globally and, it meets every three years. The Pope may come too. It will be a great coming-together of Catholic families and potentially a culture clash., writes Gerard Howlin. 

ANY renewal of the structures of the Catholic Church in Ireland can only be achieved through a wider renewal of faith, the Archbishop of Dublin, Diarmuid Martin has warned.
