[quote:2ryyo89p]Doesn’t this only apply if the wedding is presumed invalid? I don’t think we have assessed that just yet.
Joan, where is this wedding taking place exactly?[/quote:2ryyo89p]
While we are noto certain the wedding is invalid, there are several things in the post that point towards no.
Her sister is not an active Catholic.
She is marrying an unbaptized man (this requires dispensation from the bishop).
She is marrying outside of a Catholic church (this also requires dispensation from the bishop).
