David Cameron has told the nation to remember Christ's birth represents "peace, mercy, goodwill and hope" in his annual Christmas message.
It is the second year in succession that the Prime Minister has referred to Britain as a "Christian country".
Cameron was previously accused of stoking "alienation and division" by calling Britain a "Christian country".
The Prime Minister also emphasised the importance of peace and security at a time when millions had been forced to flee the fighting in Syria while Christians in some parts of the world lived in fear of persecution.
The Prime Minister said that it was a time to remember people who would not be spending the festive season in a home that was safe with their family around them.
He paid tribute to those who were spending Christmas "helping the vulnerable at home and protecting our freedoms abroad".
But the National Secular Society criticised the message, saying it was "disappointing to see the Prime Minister again pushing the divisive rhetoric of Britain being a 'Christian country' ".
Labour leader Jeremy Corbyn will not issue a Christmas message, the party confirmed.
The decision is in contrast to predecessor Ed Miliband, who last year paid tribute to volunteers who gave up their time to serve their local communities in his festive message.
Mr Corbyn's seasonal missive will instead be released in time for the new year.
