That is absolutely, one hundred percent correct, wmfights. The Eastern Church did not include the Book of Revelation into the canon until the end of the 9th century. Until that time, it was listed as "questionable" in the Church of Constantinople.
However, save for this one book, which the Orthodox to this day do not read publicly in church (which would technically make is non-canonical), all the New Testament books of the Third Council of Carthage are accepted universally as the Christian canon by all Christians to this day.
This agreement is not a legal obligation, as it would have been if the Bible had been canonized by an ecumenical council, and you make that point perfectly.
Thank you gentlemen.
I was of another opinion that proved to be false. I am indebted.
