My understanding of the Trinity is that it represents the manifestation of God in three ways.
As the Father.
As the Son.
and
As the Holy Spirit.

I doubt that such a view only existed from Nicea, but even if it did does understanding of your God cease about 2000 years ago?

This is the musing of an atheist trying to make sense of religious beliefs.
