Literally is, at least according to trinitarian doctrine. Handy diagram:
Which of course implies that “isness” is non-transitive which mathematically speaking is bonkers. I mean it’s not that you can’t have intransitive relations but calling them equivalences is going to raise eyebrows.
“Isness” definitely doesn’t need to be transitive.
It can be used to give properties to a subject. An apple is crisp, red, and 100g. Crisp isn’t red, red isn’t 100g, and 100g isn’t crisp.
It can also be used to specify a general case. Honeycrisp is an apple. Golden Delicious is an apple. Fuji is an apple. All three of Honeycrisp, Fuji and Golden Delicious are distinct.
