We rarely hear about love in the law, do we? Here is a report of a case where the term is used to describe the King’s affection for his subjects. It comes from the case of Warren versus Smith vel Magdalen College Case, Paschae XIII Jacobi in Banco Regis:

le Roy est pater patriae & sponsus regni, & est marrie al ceo ove ring sc. per son coronation, & son amor est puis que paternal ou conjugall. (1 Roll. 165-6)

The King is father of the country and spouse of the Kingdom, and is married by the ring at his Coronation, and his love is more than paternal or conjugal.

Further,

… the King, who hath been said, is persona mixta, Medicus Regni, Pater Patriae & Sponsus Regni, who per annulum is wedded to the Realm at his Coronation… (11 Co. Rep. 70)

Here we also see Coke add “Medicus Regni,” or Physician of the Kingdom, indicating that all jurisdiction over medicine and health-care flows from the King, who, if he were sufficient in his own proper person, would discharge the office, but, as he is not, similar to how he makes Judges, he makes Physicians, who enjoy a share of his Royal prerogative concerning medicine.
