Trinity
In the fourth-century, Marcellus of Ancyra declared that the idea of the Godhead existing as three hypostases (hidden spiritual realities) came from Plato through the teachings of Valentinus.[6] Valentinus is quoted as teaching that God is three and three prosopa (persons) called the Father, the Son and the Holy Spirit:

Now with the heresy of the Ariomaniacs, which has corrupted the Church of God...These then teach three hypostases, just as Valentinus the heresiarch first invented in the book entitled by him 'On the Three Natures'. For he was the first to invent three hypostases and three persons of the Father, Son and Holy Spirit, and he is discovered to have filched this from Hermes and Plato.
Since Valentinus had used the term hypostases, his name came up in the Arian disputes in the fourth century. Marcellus of Ancyra, who was a staunch opponent of Arianism but also denounced the belief in God existing in three hypostases as heretical and was later condemned for his views, attacking his opponents by linking them to Valentinus:

"Valentinus, the leader of a sect, was the first to devise the notion of three subsistent entities (hypostases), in a work that he entitled On the Three Natures. For, he devised the notion of three subsistent entities and three persons — father, son, and holy spirit."
It should be noted that Nag Hammadi library Sethian text such as Trimorphic Protennoia identify Gnosticism as professing Father, Son and feminine wisdom Sophia or as Professor John D Turner denotes, God the Father, Sophia the Mother, and Logos the Son.

So, no incarnation= no authority. No incarnation= no sacrifice. Ultimately, no incarnation= no ressurection which equals no religion.

He's either God or He is not. If he's not, we should all become Bhuddist.

The Gnostic Christians are that group who proposed the same substance theory, and then later proposed the creeds.
