 Chad McIntosh (2015) formulates a Trinity theory which is similar to three-self theories except that it adds God the Trinity as a fourth divine self. This theory is inspired by recent work by philosophers on group persons. It’s a longstanding part of legal tradition to treat various kinds of non-persons, such as corporations, as if they were persons. This is particularly useful, e.g. in holding corporations responsible for damages they cause. But some philosophers have argued for group agency realism, the thesis that some groups of persons are themselves literal persons, with interests, knowledge, freedom, power to intentionally act, and moral responsibility (168–71). McIntosh distinguishes “intrinsicist” persons, persons which are so because of their nature, from “functional” persons, persons which are so because of how they function. On this account the Persons of the Trinity are intrinsicist persons, while God the Trinity is a functional person (171).
