A human being has just 1 person, ITT we can see that the only way the trinity can be defended is either to call everyone the same human being or say that every human being consists of multiple persons. Also no see what Aquinas says "the individuals of the rational nature have a special name even among other substances; and this name is "person". So how many individuals of a rational nature do you have in your head? If it's more than 1 you suffer from multiple personality disorder. Seek help anon(s)
