I’m actually unclear on this. I am now reading that one would be valid, but I think there is more to that. Maybe someone else knows more about this.
Valid but not ratified, provided that precisely the right attitude is present at the beginning of the marriage, which would include an openness to ratifying/consummating initially, though both parties can then agree to forgo, provided that each freely embraces the choice. Such marriages are true marriages—both parties have given rights over the body to the other, and then, for the greater good, returned them. Because they are non-consummated, they may be dissolved via what is called the “Petrine privilege” (not to be confused with the “Pauline privilege” which deals with a consummated non-sacramental marriage).
