You are correct I forgot about the Confiteor but that is only one prayer not several. 
Your belief that Constantine took the authority of the Roman See to Constantinople is fanciful to say the least and I doubt that it has crossed the mind of many Protestants. I doubt too that any Orthodox Church would willingly cede the authority claimed by the pope to the Ecumenical Patriarch, primus inter pares is all he will get.
From the picture on your blog I see that you are considerably younger than I am, possibly over half my age, therefore you can have no concept of life in the Church prior to the Council except via anecdotes which are not necessarily true.  From your blog I deduce that you do not accept the teaching of the Catholic Church but prefer your own personal version of Christianity just as Luther and the reformers did.
