In most Western Christian churches, the 'Trinity' is comprised of three eternal figures: Father, Son, and Hoily Ghost. The so-called 'Sabellian fallacy appears to me to resolve a major philosophical problem, that humankind did not exist before the 6th day of Creation.

The Philosophical Paradox of an 'Eternal Trinity

During the time before the Creation of Man per se, how could Jesus exist if there were no men? And how could the Holy Spirit exist without any people with whom to form an individual connection? Some Western churches do not accept the existence of a Trinty, but none go as far as 'Modalism,' which refers to the three figures in the Trinity not all existing simultaneously. The Eastern church takes a slightly different view. The 2nd Nicene Council of 7, now renamed the Council of Constantinople, did staste the trinity exists, as a refutation of Arianism, as already decided by the First Nicene Council. However, it did not specify the Trinity as 'eternal; in its version of the Nicene creed, which is the accepted origin of the creed in the Eastern Orthodox church. But later counsels did. So in traditional Eastern Orthodox theology, the Trinity is now comprised of three equally eternal figures:

Eastern Orthodox Christians believe in a single God who is both three and one (triune); the Father, Son, and Holy Spirit, "one in essence and undivided". The Holy Trinity is three "unconfused" and distinct divine persons (hypostases), who share one divine essence (ousia); uncreated, immaterial and eternal. The Father is the eternal source of the Godhead, from whom the Son is begotten eternally and also from whom the Holy Spirit proceeds eternally. The essence of God being that which is beyond human comprehension and cannot be defined or approached by human understanding. — https://en.wikipedia.org/wiki/Eastern_Orthodox_theology

However, at least according to conventional ideas of time, the Son and Holy Spirit could not have logically existed before the Creation of Man. Are the traditional Western and Eastern creeds, that the Trinity is eternal, therefore a philosophical fallacy?

Heretical Sabellianism as a Resolution to the Temporal Paradox

There is an alternate view in Eastern Gnosticism, which accepts what is now called 'the Sabellian fallacy.' As Eastern Gnosticism is accepted in the Eastern Orthodox church, it states the following, although all orthodox theologians, including the Eastern ones, throw up their hands in horror at the suggestion and reiterate the conventional creed without feeling any need to explain the temporal issues with it:

The Greek Orthodox teach that God is not of a substance that is comprehensible since God the Father has no origin and is eternal and infinite. Thus it is improper to speak of things as "physical" and "metaphysical"; rather it is correct to speak of things as "created" and "uncreated." God the Father is the origin and source of the Trinity of Whom the Son is begotten and the Spirit proceeding, all Three being Uncreated. — https://en.wikipedia.org/wiki/Sabellianism

Whereas the Sabellian view is heretical by Eastern Orthodox views, in it the Holy Spirit and Son were 'products of the uncreation,' and therefore would have come into existence sometime after the Sixth Day, thus resolving the temporal paradox. So is the Sabellian 'fallacy,' as it named on the Wikipedia in links to Sabellianism, REALLY a 'fallacy,' or is it actually a philosophical (yet heretical) resolution of the 'equally eternal' Trinity'?
