First Council of Nicaea: when Christianity was deformed and Jesus named son of God.

[BrianSoddingBoru4]

That excerpt says it all - Arianism was the heresy, what you’ve chosen to call ‘Nicene Christianity’ was the norm and, hence, not a cult.

It does say it all, it says "Rome called the opinion it didn't like -which originated in the Eastern church- a "heresy".

And the heresy is what made them a cult. That’s very nearly the definition of a cult - a relatively small group of people with a heterodox religious opinion.
