For Better and for Worse (1992)

A young Catholic couple contemplating marriage gets divided by their separate heritage--she's rich, he's the son of a butcher. However, the real pressure comes when a publicity stunt to lure the Pope to their wedding as a symbol of the unity of the Catholic Church goes awry when the Pope actually accepts. This sets the press on their heels and increases the pressure on them until they consider calling off the whole wedding.
