**From what I understand, in an average mixed marriage between an RC and a non-RC the couple must promise to raise any children that they have as RCs. What about in the case of a Royal Mixed Marriage? **
**I ask because this has happened before. Anglican Prince Michael of Kent married an RC, Marie-Christine von Reibnitz, and their two children, being so close to the British throne, were raised as Anglicans.
More recently, Protestant Crown Prince Willem-Alexander of the Netherlands married a Catholic woman named Máxima Zorreguieta. They just recently celebrated the baptism of their daughter (and future Dutch Queen) Catharina-Amalia. I seriously doubt that little Catharina-Amalia is being raised as an RC.**
**Do Mixed Marriage Royal couples have to make a promise to raise the children RC? Is this kind of thing left in the hands of a bishop?
