Enough is enough, stop writing your own musings, you are just winging it. There is no point in discussing anything with you because you live in your own world. Heresy is a defined term that anyone can look up in one second.

71. Schism and Heresy
What is schism; and what is heresy? --Schism is the refusal to submit to the authority of the Pope; heresy is the formal denial or doubt by a baptized person of any revealed truth of the Catholic Faith.
What were the most important schisms and heresies that have tried to destroy the Church? ......
The greatest schism suffered by the Christian Church was that of the East, resulting in the establishment of the Orthodox Eastern Church. The Eastern emperors, desiring more power in the Church, tried to make the patriarchs of Constantinople independent of Rome. Finally, Photius, with the support of the emperor, held a council of Eastern bishops in the year 867, and broke from Rome.
The cause of the schism was not doctrinal, but rather political and material,- jealousy between the East and the West. It has resulted in the separation from Rome of 145 million people with valid priesthood and sacraments. In the United States there are a number of schismatical churches, among them the Greek Orthodox, and the Russian Church.
After minor schisms and misunderstandings between East and West in 1054 there was a final break by Cerularius, patriarch of Constantinople, continuing today.
Today the Orthodox Eastern Church remains in schism, but does not spread. It is a withered branch, having cut itself off from the parent tree.
The Orthodox Eastern Church denies the Catholic dogma that the Holy Ghost proceeds from the Father and the Son. It also teaches that the souls of the just will not attain complete happiness till the end of the world, when they will be joined to their bodies; and that the souls of the wicked will not suffer complete torture in hell until that last day. These are heresies against the doctrines of the Church.
Thus it can be seen that today the Orthodox Eastern Church is not merely schismatical, but truly heretical; for it holds primary doctrines in a different light. But it has valid orders. (See Chapter 55 on The Catholic Eastern Church; Rites)

There is not really any question of doctrine involved. It is not a heresy, but a schism. The Decree of Florence made every possible concession to their feelings. There is no real reason why they should not sign that Decree now. They deny papal infallibility and the Immaculate Conception, they quarrel over purgatory, consecration by the words of institution, the procession of the Holy Ghost, in each case misrepresenting the dogma to which they object. It is not difficult to show that on all these points their own Fathers are with those of the Latin Church, which asks them only to return to the old teaching of their own Church.
