I believe that the royal family are a focus of patriotism, of loyalty, of affection and of esteem. That is a rare combination, and we should value it highly.

Our reading
An editorial interpretation.
The speaker presents the monarchy as a rare place where four good feelings meet: patriotism, loyalty, affection and esteem. Rather than any one of them alone, it's the combination that's called valuable and uncommon. It's a statement of one political viewpoint, offered as a reason to prize the institution.
