"The point is if he isn't a Catholic then his previous marriages count as do the divorces, so it seems he must be saying he is a Catholic and those marriages and divorces don't prevent him marrying in a Catholic church. If he wasn't a Catholic then he would have to have the previous marriages annulled, which of course he might have. I believe it is easier to do than it used to be."
Dear 'theworriedwell', I think you (and several others) are missing the point. Since neither of Boris's previous marriages took place in a Catholic church, then - so far as the Catholic Church authorities are concerned - these marriages had no religious standing whatsoever, and did not therefore need to be annulled. The only information currently in the public domain is that Boris was born and initially raised a Catholic, but was subsequently confirmed into the CofE at school. Now, he may still be CofE; he may have rejoined the Catholic church; or he may even have finally seen the light and come over to the Free Presbyterian Church of Scotland (unlikely, in this context at least) - we simply don't know (and why should we?) But, as I understand it, all he (or anyone else) had to do to get married to a Catholic lady in a Catholic church was to agree that any children would be raised in the Catholic faith.
If he was a Catholic the other marriages are not recognised. If he wasn't a Catholic they are. I think you are the one missing the point.
