Mark Davies, the Roman Catholic Bishop of Shrewsbury, used a Christmas sermon to link plans to legalize gay marriage in Britain to Nazi attack on religion.

Prime Minister David Cameron's Conservative Party has fast tracked a vote on the issue in the New Year.

In his midnight mass, Davies accused Cameron of attempting to redefine marriage in the name of progress for “generations to come” without a mandate and “without any serious consideration,” the UK's Daily Mail reported.

“Past generations have gathered in this cathedral on Christmas night amid many shadows which seemed to obscure the future for them. We think of the ideologies of the past century, Communism and Nazism, which in living memory threatened to shape and distort the whole future of humanity. These inhuman ideologies would each challenge in the name of progress the received Christian understanding of the sanctity of human life and the family. Winston Churchill, Britain's wartime prime minister, a man without clear, religious belief, saw in this deadly struggle nothing less than the defense of Christian civilization.”

Ruth Hunt of gay rights advocate Stonewall called Davies comments “deeply offensive to gay people and their families.”

“Gay people are all too aware of the horrific results of Nazi ideology due to the countless casualties of the Holocaust,” she said.
