I don't know Spanish law, but it's not the US, and certainly separation of church and state is not a widely accepted policy in Vatican City. There are many legitimate discussions to be had there, too, since Spain is under no obligation to accept any papal influence over its laws (and as a foreign head of state, whether or not everyone is willing to accept that, there's strong reason NOT to allow his influence over Spanish law). The Pope retains the title of "Christs Vicar on Earth", however, and Roman Catholic canon law is quite explicit on both points. When consecrating a church in a country where profaning a Catholic sacrament is now protected by federal law it would be irresponsible not to comment on the latter.
