I don't think it is a simple as 'right or wrong'. There are reasons for taking both paths of action.

Being a godfather is also a bit different from church to church. In my country it isn't a problem to have a 'non-religious' godfather since the (major) churches generally view a godfather as someone who will/can partake in raising a child if needed, and often it is only a 'honorary' title anyway - not necessarily with religious undertones - as weird as it may sound given the title.

I was the godfather of my niece and didn't need to express an religious sympathies in doing so. It is more a ritual acknowledging my position in her life and a 'grace' extended by my sister as a recognition of our family connection.

If I had been asked by the priest to 'say' religious words I'd have explained my situation and explained I would want to express myself differently and probably focused more on moral values than religious content.

I'd say your decision was very moral, but morally right decisions can also have negative consequence.
