What would a change of religion signify today?

There are fewer and fewer countries with a state-dictated religion, and those are mainly Islamic. I can't see any of those changing any time soon.

A *person* changing their religion in such may come under a range of sanctions and punishments, depending on the country and the circumstances.

Attempts to combine secular rights with religion have often left uncomfortable tensions:

See Egypt, Turkey, and Malaysia (url) for examples:

"The latest court ruling suggests that people born as Muslims in Malaysia do not have a choice of religion in spite of constitutional guarantees."

England, as so often, has managed an unusual fudge in its religion, From Henry the VIII's essentially English Catholic Church (it was hardly protestant) via the extremes of Mary and Elizabeth through to William and Mary, and the slow restoration of tolerance for Roman Catholics, unofficially and more formally in the Victorian era and, nowadays, a state religion which is for many essentially symbolic and traditional. That no Catholic, or person married to one, can stand in succession to the throne remains one last outstanding protestant law.

I think you need to look at a few history books.

When England changed its religion it was partly made possible by the Reformation and the schism in the christian church that was happening all over Europe.

Henry 8 and his advisers made use of the thinking of emerging protestantism to make the break - And under Elizabeth it became a properly protestant church

Change of religion by a state should be considered a turn back toward the dark ages, since a state should not be associated with any religion.

I thought England separated from the continent during the Cambrian period....?

the more you change religion the more you make it more divisive and more you make more wars, it just isn't good to change people's strange beliefs.

nothing religion is lame

it is all human made

and a waste of my time
