Catholics and Eastern Orthodox are unified in the theology regarding salvation. Here, this might help: Greek Orthodox - How Are We Saved.
I have one more point to make which the above link illustrates very well. I often see where Protestants try to make the case that they are close to Eastern Orthodox in belief, i.e. much closer than to the Catholics. But that is just not the case. Catholics and Eastern Orthodox are much closer than are Protestants and the Orthodox. Besides the faith and works difference illustrated below, Catholics and the Orthodox have the seven sacraments in common and much else in their theology. Unfortunately, the Catholic and Orthodox aren't fully united in doctrine, but they are much closer than are the Protestants.
The link you posted is a perfect match to what Protestants believe and the exact opposite of what Catholics believe according to your own CCC.
Now stop blaspheming and telling falsehoods about non-Catholics.
And they are still not in communion by your own words.
