Thank you for sharing these quotes...this shows that there was an evolution of thought throughout history that finally culminated in official pronouncements made later. I'm not arguing that this didn't happen. ..thanks for your best wishes and you have a great night too.
Actually, dear friend , it shows that the Trinity was always believed in the same fashion that Jesus is God was always believed and in the same fashion we use to authenticate the Gospels.We authenticate these things through the writing of the early Church Fathers
Early Christian beliefs were already considered dogmatic before the council of Nicea based upon united traditions from the Apostles to the early Church fathers
What developed after The first Council of Nicea after Christianity became legal was things like Macedonianism(similar to your belief) that ended up being condemned at the Council of Constantinople to protect people from this rising error.
Sadly ,over time error's like Macedonianism got resuurected again to gain ground to mislead people due to the reformation.
