I've recently been studying category theory (mathematics), in which the relations between objects are generalized to a very abstract level. I was wondering therefore if the relations between the Father, Son, and Holy Spirit could be expressed in terms of concepts from category theory.

The explanations and analogies for the Trinity are often inadequate / oversimplified, but due to the nature of category theory I thought there may be a way to express the Trinity in terms of category theory.

This question of course calls for some background knowledge in category theory, which not everyone may have, but I appreciate any answers anyone can provide!

    People have difficultly explaining the Trinity with words. It would be orders of magnitude more difficult to do so without words. – curiousdannii Jun 22 '22 at 03:54

    The revelation of the Deity is in the sending of the Son. If individuals do not hear His word and believe on him, they will have no understanding of the Deity. Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son. 2 John 1:9. – Nigel J Jun 22 '22 at 10:23

    Would the answer be significantly different from the mathematics represented by the standard "is"/"is not" tetrahedron diagram ? – Ray Butterworth Jun 22 '22 at 14:10

  • Category theory in the mathematic sense can't describe it any better than those analogies by definition. The terms used to describe the Trinity in part are developed because of the Categories of Aristotle (cf. Augustine's de Trinitate) – eques Jun 23 '22 at 23:10
  • Good luck, you're gonna need it. – Only True God Jun 24 '22 at 03:14
  • One issue you might find is that there isn't one theory of the Trinity within Trinitarianism. Rather, there are a bunch of them, which becomes clear once you start pushing on various issues related to it. – Only True God Jun 24 '22 at 03:57
  • @OneGodtheFather Still haven't recieived a good answer to my salvation objection since you ghosted that comment thread ;) – Luke Hill Jun 24 '22 at 04:47
  • @LukeHill Can you link to your objection? I'm happy to take a look at it. – Only True God Jun 24 '22 at 05:08
