What it says on the tin really. Been asked by my SIL to become Godmother to my nephew. I'm an atheist and her kids are being baptised into the Catholic church in April as their dad is a Catholic. I'm really close to my nephew but think she should ask someone who is a practising Catholic. She says it doesn't matter but I'm not so sure. Is this the done thing nowadays? We were brought up with zero religious instruction, any advice before I'm shunned for turning this down?
