Harry's Christening

[Caius Marcius]

>From JKR's Q & A in Edinburgh:

"Does Harry have a godmother? If so, will she make an appearance in 
future books?"

"No, he doesn't. I have thought this through. If Sirius had married
 
Sirius was too busy being a big rebel to get married. When Harry was 
born, it was at the very height of Voldemort fever last time so his 
christening was a very hurried, quiet affair with just Sirius, just 
the best friend. At that point it looked as if the Potters would have 
to go into hiding so obviously they could not do the big christening 
thing and invite lots of people. Sirius is the only one, 
unfortunately." 

In my dictionaries 'christening" is defined as a 'baptism', which in 
the USA these days is a ceremony that would only be conducted if the 
family had some affiliation with a Christian church (however 
nominal). Does the same thing hold true in Britain? Might a British 
family circa 1980 have held a "christening" without any affiliation, 
involvement or belief in a church?
