My granddaughter mentioned looking forward to this ceremony, which I find horrifying. How could I possibly attend such a farcical occasion? Her parents are not together & I'm sure this comes from exposure to her other grandmother.
As a former catholic I can assure you, it is not just the religious significance for your god daughter but a social move as well. First communion is seen as a step away from childhood and towards adulthood, may be you can get behind that element ? It is emerging into the age of reason that allows the person to receive the sacrament, so don't go all preachy but congratulate her on growing up. Also it is a HELL of a big deal when you are a kid. Believe me !
Ritualistic cannibalism has been something in Christianity and Catholocism (sp) since Jesus' death. At least its not real humans or blood. While I agree that it is a waste of time, I'd just go along with it. Railing against something you have no control over won't get you anywhere.
I don't have children, so no grandchildren. I do have nieces that I adore. Their parents (my sister and her husband) aren't religious, so neither are the girls. However, they did attend Catholic Sunday School because their grandparents wanted them to and the girls weren't averse to it. Had they wanted me to attend one of the Catholic ceremonies, I would've done it ... just because they asked it. Each person explores their relationship with religion (or no religion) as they're growing and maturing. I don't believe my nieces are likely to become Catholic (despite the grandparental attempt at indoctrination), but I would love and respect them even if they did.
