This is a false statement, as 30 seconds of research on the Internet would have shown you.
If it’s a false statement, it’s only so in the mind of the RC church. Unless you wish to redefine the English language, annul means, “To make or declare void or invalid”. When you “annul” a marriage, you are sayng it is void and invalid. Therefore, what I’ve said is true unless you wish to dance the voodoo, mumbo-jumbo, theological contortion BS of the RC church.
