On several grounds - firstly because I feel in this day and age if you want a naming/welcoming to the world ceremony it doesn't need to be in religious context. I feel it's hypocritical when the parents aren't religious and have no plans to become so, and not allowing a child to have free choice in later life about their spiritual choices - you can't be unbaptised! It's one thing bringing a child up in a culturally religious context or with the teachings of religion or spirituality but I feel especially if you don't actually believe in God baptism of a child without them knowing what it means and agreeing with it isn't right.
DP thinks I'm being highly unreasonable even suggesting I won't go to a (not even remotely close) friend's new born and 5 y/o daughter's joint christening ceremony because I feel it's not right, in the same way that people that don't have religious families or are religious themselves shouldn't have a wedding in a church just because they like the venue. It makes it a meaningless practice! (I'm not religious btw, but I am spiritual) I'm aware I'll most likely be hounded out of town but I just wondered if anyone felt the same?
