Mary I's husband Philip was also legally King of England.

I thought the whole point of the Anglican Church was that divorce/remarriage is okay. What with it being created so that Henry VIII could divorce and remarry and all.

Right. I wanted to say that, but I forgot. my understanding was that the King could be divored but he coulen't, for reasons that remain unclear to me, marry a divorced woman. Or a commoner, maybe. Or a divorced commoner?

Deacons in the Russian Orthodox Church are not supposed to remarry, evn if they are widowed, which is why my grandmother's second husband had to quit being a deacon to marry her. The straightforward remarriage is forbidden I understand. British royalty seems to operate under a muddier set of rules.

Henry VIII's divorce wasn't actually a divorce in modern terms.

He didn't want to dissolve his marriage to Katherine of Aragon; he wanted never to have been married to her at all. In modern terms, he wanted an annulment.

No, the point of the Anglican church is that Henry VIII can do whatever he damned well wants to. Divorce just happened to be the inciting incident.

Well, but still. Divorce was pretty explicitly part of the package.

Ah, I guess that does make a difference. But still. t does hand-wavy gesture of non-understanding

Huh. I didn't know that.

Mary I's husband Philip was also legally King of England.

He also had a screwdriver named after him.

He could be divorced but couldn't remarry. Diana died, solving that problem.

If he marries a divorced woman, it's technically adultery because "Christian marriage is indissoluble." So he's sleeping with another man's wife.

Commoners aren't a problem. Legally, Diana was a commoner; although the daughter of a Duke, she wasn't noble herself.

Yes, I obsess about these things.

Pretty much. Plus Charles isn't as likely to be able to chuck the Archbishop in the Tower with a view of the scaffold as Henry was. Not that I don't imagine the Royals think fondly of those times.

The divorce/remarriage thing is one of those "observed in the breech" things. In the modern world, divorce and remarriage are so common that the church has to let to go in order to survive. But the British Monarch is the Head of the Church, so s/he is held to the letter of the rules. The Princess Consort thing is a face-saver for all sides, because, technically, the last woman standing at Charles' side by the time of the Coronation would be Queen Consort. Much of England, I understand, gets very twitchy at the idea of Queen Camilla, whereas Her Royal Highness, the Princess Consort keeps the brick-throwing down.

Ah, I guess that does make a difference. But still.

Here's the deal. Henry VIII married his brother's widow, Katherine. The Pope had to give him a dispensation because that's within the legal bounds of consanguinity.

Henry VIII wanted out of the marriage. The Pope wouldn't annul his dispensation. Therefore if Henry assumed the power of the Pope, he could say the Pope never had the right to give him a dispensation in the first place, and thus he was never married.

There's a whole separate issue of whether Arthur slept with Katherine; if he didn't, Arthur and Katherine were never legally married, thus no consanguinity problem. Katherine said they didn't consummate the marraige.

Hee! Mistress cage-match!
