EDIT: For those of you that keep jumping the gun on this thread. This is not about me interfering with how my sister raises her kids. This is about me personally deciding if I would attend any religious ceremonies in the upbringing of those kids, and if I didn't go, how I would word my refusal in the politest ways possible.
My sister is getting married soon and reproduction is likely to follow. She is getting married in a church and I'm a little worried about what I will do if they decide to get the Kid(s) baptized.
On the one hand, I don't particularly think it's my place to tell my sister how to raise her kid(s), I would of course like to be involved in their upbringing, my sister (or her fiance) isn't especially religious anyway (getting married in a church being about the height of it), and I have no desire to create any disagreement.
I suspect that baptism is likely however, in an assumption of that's just how things are done - these are the ceremonial motions of raising a child - kind of way. I never really had a conversation with my sister about her precise beliefs. Although I suspect she does have very precise beliefs.
But on the other hand, I find the idea of imposing religion upon a child extremely ethically objectionable. While I would happy to have a role in the upbringing of any children, a religiously framed 'godfather' role (I have no idea if this is likely) would be unacceptable to me, and I would be extremely reluctant to attend any baptism or other indoctrination ceremonies.
Having your child marked down as 'Catholic' can be an advantage for getting into schools (most schools in Ireland are church sponsored, although secular schools are on the rise). As far as I'm concerned the reaction to that should be to vote for people who advocate a secular school system, send your child to a secular school, or raise your family in a non-discriminatory jurisdiction, not pandering to the system by indoctrinating your child. But..anyway.
Basically, this is something that I am going to have deal with down the road, and I would like to have an idea of what I am going to do in advance.
To put this in context, my sister is great and we never argue about anything ever. I fear I will have make some inquiries about her beliefs though, which is not something I want to do near to her rapidly approaching wedding (If they want to get married in a church, that's their business, no need to create any bad feeling about that).
Further context: While both my parents have had (reading, minister of the eucharist) active roles in the church, religion was never really present at home, and this has kind of died down in recent years. I attended mass with my family for years, without participating in prayer or communion, to avoid any conflict over the matter. When I did eventually (after a couple of years in college) put my foot down on the matter, it did create some consternation but went over relatively peacefully. My mother's main objections are that it is 'nice' for a family to go to mass together and that church is a good place to keep in touch in people in the community. I never discussed the matter with my sister. The height of religious discourse in the house is when I write references to original/influencing festivals on 'christmas' cards. Politically, I don't think anyone in the family would agree with any of the church's positions, except maybe on abortion, although that is a strange issue in Ireland (it still being illegal here).
