“In respect of age only does a father take precedence of his son amongst men, for in regard to generic nature the father is on a level with the son, and in other respects the son may even excel his father. But where the Persons are eternal, there is no difference constituted by age. Still, as St. Ambrose acutely remarks, the names ‘Father’ and ‘Son’ indicate indeed a distinction of Persons and mutual relations of those Persons, yet not diversity of nature—rather, in fact, suppose equality and unity of nature.”—Hurter in loc.
