It was mine too. As a former grandchild and present grandparent, my opinion is that access to your grandchildren is a privilege, not a right, and that privilege needs to be earned. Like ossobuco says, if you show up and are always finding fault, saying things like "we never let children do x y z in my day", making remarks about religion, telling your son's wife she doesn't cook things or keep house properly, or making tactless remarks that could be read that way, whatever, in short, interfering, you should not wonder if the invitations are slow in coming.
Of course that might not be the way it is at all.
As for the religion thing, I was raised Church Of England (Episcopalian) and I remember my father telling me at various times:
1. The Pope in Rome and the Soviet communists in Moscow were in a joint plot to control the world.
2. My recently deceased mother would "spin in her grave" if I joined the Salvation Army. (I think my 14 years old bereaved grieving self clung to religion for comfort) My favourite aunt was a Major and later a Lieut. Colonel in the Salvation Army, and she had defied much family opposition to join that body.
3. There is no God, and all religions are no more than superstitions. (You'd think that this would contradict the other views!)
So you can see I think you should back pedal on the religious thing. There was only one Jesus.
I am now an atheist, but I think that if I ever went back, I'd be a Catholic. I'd support married & women priests, contraception, etc, rather like some of the radical Jesuits in Mexico and other places. And I like the statues and pictures.
