National Apostasy anybody?

This is not a political blog, not even an ecclesiastically political blog, but I feel like I have to post about this.
Perhaps you have all heard the recent news from the UK.
Owen and Eunice Johns, who have been foster parents for a number of years now, have been told by a judge in England that their conservative Christian views on homosexuality exclude them from being suitable foster parents, because their views might be harmful to children.
Now first, I think this is an outrageous and totalitarian decision, but what really gets me is that the judge says there is no place for Christianity in the laws of England. . .
Really? Last I checked there is still a body called the CHURCH OF ENGLAND. Maybe it is because I am an American, but I cannot grasp the sheer madness of a judge in an avowedly CHRISTIAN NATION WITH A STATE CHURCH saying that Christianity has no place in the laws of the nation. That makes some sense in an nation like the United States of America, but how can it possibly even be uttered in anything but jest in an English law court?
And if John Keble thought things were bad when the state abolished a few Irish dioceses, what would he have to say about this?
