Goodness, I am feeling very guilty.I have never really considered giving my sons godparents, despite the fact we have hardly any family.
I am a godparent but I have totally lost touch with my godson. I have only seen him twice as a baby and have even forgotten his name. I was asked to be a godparent when I was about 20. My friend was the first of our group to have children. She chose my then boyfriend and I mostly because she met her husband through us. It was a social nicety. I was a sometime church goer,a Bapist, but it was a second 'baptism' in your teens, not christening and godparents that had importance. So I was pretty ignorant about my duties.
A year later I had parted company with my boyfriend, and my friend and I were living in different cities. We swapped christmas cards and letters,but our lives were so different that we just lost touch. At the time, single, no children etc I hardly gave it a second thought.
Now I can more easily appreciate the role godparents can play. Our children aren't christened (though we are considering the possibilty), so they have no godparents. If I were to choose godparents I would pick adults who had already shown some interest in my sons. I would try to see the person from my sons point of view rather than mine. Some of my best friends, very good people, are just not very interested in children. I would also choose people who are likely to stick around. I don't think I would be materialistic or calculating in my choice of godparents though it would be tempting to give my children potential access to more monied or well-connected adults than us!
I would not expect godparents to provide spiritual guidance - they could be athiests for all I am concerned. I would not expect them to take on any parenting responsibilities in my absence. If you choose godparents when your child is a baby, you have no idea what sort of personality your baby will have, or how they will interact with the people you have chosen as their godparents. To me the 'parent' bit is symbolic unless a firm relationship builds over time.
I would hope, however that the godparents could provide some moral guidance if called on. But most importantly I hope they would be willing and able to befriend my sons.
Just a thought. Do you have to choose godparents when you child is a baby? what about waiting till they have some 'favourite adults' and you can make a more informed choice? I know little about the church implications of this.
