"only the exclusive and indissoluble union between a man and a woman has a plenary role to play in society as a stable commitment that bears fruit in new life."(Amoris Laetitia)
And that is what must be at the core of community life. When David Cameron made a dignified and manly speech on resigning as Prime Minister, the only bit that really made the whole thing suddenly flop was his bragging about having legalised same-sex "marriage".
All the excitement and politicking happening in Westminster at the moment is of much less importance than the great reality at the heart of the West: the collapse of an everyday, shared recognition about the nature of man and woman and marriage and family. The future of society is through families: to renew faith in that is to offer hope.
