First, thanks to everyone thats replied.
its not going to be a naming ceremony, when i originally agreed i thought it would be, but now its going to be a full on religious thing so that he can get married in church when hes older.
With regard to this, its my best friends child. I'm going the be there for it anyway, all the other things you mentioned can be done and would be done as a matter of fact, without even thinking about it. Its what you do.
Being a god parent, i assumed means that if anything happens to them i'd look out for their child. which is what I'd do anyway, but its also ment to be about religious guidence and things, I dont have a problem lying to the vicar/priest whomever saying that I was baptised/christened when I wasnt.
What I do have a problem with, is going through all the circus myself, I really dont think I could reconcile going somewhere and being judged by someone who has no idea what life in the real world is like.
For example, what can a priest tell anyone about love and things, when they're not allowed due to their religion to get married or fall in love?
No wonder a lot of their sexual desires are expressed in deviant ways.
The prejudice of religion I really have a thing about.
Someone may repent their sins so they can goto heaven, but they've still sinned.
Someone may live a sinfree life, but if they dont believe in a particular religion then they're looked at worse than the person who repented.
Myself, I pefer to be agnostic, but it isnt even agnostic.
I believe that the ancient religions with multiple gods are more likely to be true if anything is... and that these multiple gods, if anything, if they even exist are more likely to be mans first interpretation of aliens. (and i consider that highly unlikely... but its on the more believeable scale than an all-seeing all knowing god)
I could deal with it if they wanted to endoctrine their child into the buddist faith or something like that, being spiritual, or teaching someone to be spiritual is one thing, but following something that inflicts standards of living on others, or forcing a child into something that causes it to make value judgements on others, is nothing but wrong in my eyes, and this is why I morally object to it.
But then, its my best mate...

That could be my way out of it, but I have no concern about lying. They can not prove that I have not been baptised. Its just reconciling my own thoughts about it all.
