schism.....
The East–West Schism, commonly referred to as the Great Schism of 1054, is the break of communion between what are now the Eastern Orthodox and Catholic Churches, which began in the 11th century and continues.
The Eastern (Orthodox) and Western (Catholic) churches are the two main branches of Christianity. The Eastern Church is composed of national churches that are in communion with the Patriarch of Constantinople, while the Western Church is under the jurisdiction of the Pope in Rome. The two churches have different theological traditions and practices. The main differences between the Eastern (Orthodox) and Western (Catholic) churches are: -The Eastern Church uses the Byzantine Rite while the Western Church uses the Latin Rite. -The Eastern Church is organized into Patriarchates while the Western Church is organized into Dioceses. -The Eastern Church teaches that the Bishop of Rome is the first among equals while the Western Church teaches that the Bishop of Rome is the supreme Pontiff. -The Eastern Church is composed of national churches while the Western Church is composed of local churches 678217.
The split between the Eastern Orthodox and the western Catholic Churches was caused by a number of different factors. Namely, neither side could decide on the Pope's role in the church, or the scope of his authority.
The main difference is the authority of the pope. Catholics accept it, Protestants and Orthodox don't. There are some differences in the cannon (list of books) included in the Old Testament (although they all have the same New Testament). There are several different types of Protestant religions (Lutheran, Methodist, Anglican, etc) which have differences between themselves and differences between Catholic/Orthodox. So complicated to get into more specifics.
Your question is too general. There are many things that were not a cause of tension between these belief systems. The colour of my dog for instance
The Great Schism was between the Roman Catholic Church and the Eastern Orthodox Church (or Catholicism and Eastern Orthodox).
To differentiate between Eastern Orthodox, Oriental Orthodox, Assyrian Church of the East one would use Roman Catholic.
Both began as forms of European Christianity. -Apex- :)
1)The filoque in the Nicene Creed (Orthodox say that the Holy Spirit "Proceeds from the Father," whereas Catholics say that the Holy Spirit "Proceeds from the Father AND the Son"). 2) The Orthodox go by the Julien Calendar, whereas the Catholic goes by the Gregorian Calendar.

He set himself up as a rival king in the West in 800 AD, and this offensive act caused the beginning of tensions between the Orthodox Emperor in Constantinople and the barbarian rulers of the West. This increased the separation and differences between the Latin West with the Orthodox East and eventually led to the Great Schism of 1054 AD.
