The way the phrase “alter ego” is employed in English (often in the sense of an alternative identity or personality of a single person — not literally a distinct person), using it in reference to the Persons of the Trinity would seem to imply Modalism. But if we just boil it down to its component parts, where the first word means “other” and the second word means “I,” then yes, in a sense, there are three distinct Persons, so yes, perhaps it fits (even if others might balk, out of concern it was meant pejoratively).
Interesting, well i think that “Alter Ego” is not a proper phase to use when talking about the Trinity…It would infact fit really well when talking about only Jesus himself for example the “Communicatio Idiomatum”
