Britain is under threat from a rising tide of "militant secularisation", a cabinet minister has warned.
Religion is being "sidelined, marginalised and downgraded in the public sphere", Conservative co-chairwoman Baroness Warsi wrote in an article for the Daily Telegraph.
The Muslim peer said Europe needed to become "more confident and more comfortable in its Christianity".
She will also highlight the issue in a speech at the Vatican later on Tuesday.
"I will be arguing that to create a more just society, people need to feel stronger in their religious identities and more confident in their creeds," she wrote in the Telegraph.
"In practice this means individuals not diluting their faiths and nations not denying their religious heritages."
Baroness Warsi, who is Britain's first female Muslim cabinet minister, went on to write: "You cannot and should not extract these Christian foundations from the evolution of our nations any more than you can or should erase the spires from our landscapes."
