The headline on this piece is potentially misleading, because it implies Christianity is a 'minority' religion.
Christianity is by far the largest UK religious group at 46.2% of the population (a stat bizarrely not mentioned in the article).
The 'minority' issue stems from rising numbers identifying as "no religion", 37.2%.
The 2nd biggest 'religion' is Islam at 6.5%.
Headline writers need to be much more sensitive when framing stories like this.
