You really walked into this one Benice. 
Nigel Nessling, devout mccann supporter.
Just for starters.
Claims that Madeleine signifies the second coming of Christ.

Thankyou for the link.
I am not a Christian but as far as I know Armageddon and the 'second coming' are believed by billions of people worldwide who do not consider themselves to be part of a cult.
The subject of the article is Armageddon and is an interesting observation of modern day 'major events' in the world which the author relates and connects to the prophecies in the Bible regarding the apocalypse and the 2nd coming.
Madeleine's case can without doubt be described as a 'major event' as it is known about worldwide (and is still being discussed 10 years later) - and in the opinion of the author is another example of those events which he believes bear out those biblical prophecies.
As I said I am not a Christian so it doesn't work for me. But as the author is obviously a committed christian who believes in the Bible I can see where he is coming from. IMO his theory is intriguing, very well-researched and is backed up with cites. Whether it is correct or not - is matter of opinion.
However, there is nothing in the article which even hints that any of the McCann family should be worshipped - or compared to God.
