Ladyfish - congratulations on the birth of your grandchild.
I was brought up in the Methodist church. My Mum ran young wives, my Gandfather was a lay minister, we went to Sunday school, all the social events, everything.
I am not now a Christian, in that I am an athiest, and have no faith in god. BUT I do think all my values are very much based in the conversations I had with my grandfather from a very young age, and the wider philosophy of Chritianity.
They never pressurised me to follow the church: the whole approach was that everything we do, we are accountable to our conscience. Including church membership or belief in god. All was presented in 'make your own decision about everything you do - but know why you do it and accept responsibility for it'.
I am sure you have brought your dd up with strong values - be proud of her...but do not feel sad for her. She will have her own strengths and sources of reflection to live her life with the values she learned at home with you. If you feel sad for her, you are, by implication, saying that you are disappoiunted in her, or only your faith and choices wil be the right ones.
I think it must be hard to have an absolute faith and to see your dd not continuing in that faith, but in allowing me to make my own choices, without pressure, implied criticism or 'sadness' on my behalf for my choices, my family ensured that, in fact, I have complete respect for their choices, I am grateful for what it gave me, and I hope that if my grandparents are watching from the heaven they believed in, they will be proud of me, not sad - as I am for the lives they led.
Good luck - I hope you are able to enjoy your grandchild without awkwardness in the family.
