Throughout its history the Christian church has undergone two major splits:
The Protestant Reformation.
The Eastern Orthodox Church split from the Roman Catholic Church in 1054, in an event known as the Great Schism.
The Roman Catholic Church and the Eastern Orthodox Church.
Please specify which split you are referring to.
The two Christian churches that developed after the split in 1054 are the Roman Catholic Church, based in Rome and headed by the Pope, and the Eastern Orthodox Church, which has its headquarters in Constantinople (modern-day Istanbul) and is led by various patriarchs.
They formally split the Christian Church apart They created two completely separate churches.
The revolt of Martin Luther against abuses and teachings within the Roman Catholic Church. Specifically, the event where he nailed his so-called '95 theses' to the doors of The All Saints'Church in Wittemberg, Germany in 1517 AD.
They formally split the Christian Church apart They created two completely separate churches.
The Christian religious branch that split from the Roman Catholic Church in the 16th century was Protestantism. This split was initiated by Martin Luther and led to the Reformation movement, which resulted in the formation of various Protestant denominations.
The first split between the Christian church in the East and the Christian church in the West probably took place during the time of the Byzantine Empire. Some of the issues that caused this split were that the Eastern emperor viewed himself as head of the church as well as ruler of state, and the Pope in the West viewed HIMSELF as head of the church, and a varying opinion over idols. The Westerners had no problem worshipping/praying to idols, because many of them couldn't read, but the Easterners felt that it was wrong to worship an image. Thus, the church split into the Roman Catholics and the Greek Orthodox.
Short answer: it was one of the causes of the split between the western and eastern Christian churches. The result of the split (schism) is the Catholic church (western) and Orthodox church (eastern).
When Martin Luther nailed his 95 Theses to the church door in Wittenberg in 1517, it sparked the Protestant Reformation, a major movement that led to the split of the Christian Church into Catholic and Protestant branches.
