I see what you did there. But the clue is in the name ‘god’father.
I think many people, especially 50 years ago, perhaps nominated people close to them but unrelated, more out of recognition of that closeness and a sense of tradition, rather than devout faith in a deity. My parents have never been religious but myself and my two siblings all had godfathers/mothers.
Kind of like picking a best man, but for your baby, and someone who might stand a chance of being responsible should the worst happen.
These ceremonies are what people choose.
Indeed, I fully respect that, and that is my proportionate side.
My disproportionate side however, would much rather just hear about his life without the frequent plugging of the big man.
