I am an atheist but I was Christened ,as were my parents I believe, and
my daughters were Christened, but not for any religious reasons. We didn't know the word Baptism. We all had God parents. I don't think my daughter's God Parents were asked any questions .
I'm aware as I write this how hypocritical it may sound but it's not, because
we never gave it a thought. We just did it because it was what was done at the time. The child was born , you registered the birth and you had to have it Christened , end of story.
I was in a vicar's house on one occasion when a couple were coming up the drive and the vicar's wife said " Ah another three wheeler ! " She explained later it meant that was the only times they come to church, were for
Birth ,Marriage, and Death.
