 Koons argues that this theory has many advantages over some rivals. Against the constitution based three-self theory of Brower and Rea (see section  2.1.3),  it allows for divine simplicity, as the Trinity does not involve any metaphysical components or parts other than the divine nature. And he claims that their account amounts to tritheism, “since each Person is divine in His own unique and incomparable way”. In contrast, on Koons’s theory, “each of the three Persons is divine in the same way–simply by being a divine qua-object, and the divine nature is complete and fully divine in itself”. Again, Koons’s theory can, and theirs can’t, explain why there are exactly three divine Persons. And their theory requires three different odd and hard to explain personal attributes (352). As contrasted with any “social” theory, this one doesn’t have divine Persons which are really distinct from the divine nature (God) (353).
