Who were the first Church fathers to start the rumblings on the nature of the Trinity that closely reflect what the Orthodox Church teaches today? I imagine the idea didn't just pop up during a meeting in the 4th century. I've read some of the Church fathers from the first or second centuries that sorta kinda hinted around at the idea, but it's not fully defined at the time. It seems it may have been a theory amongst some of the very first Christians, but just how did it become the winning theory in the 4th century?
I know the idea probably a pretty complex path to it's acceptance by consensus, but maybe you can give a brief outline of the history with a recommendation of where to look from here. :)
