Answer:
The controversy arose from the practicing of artistic works of Christ's life in the zone influenced by Constantinople, while Rome was furious about it and was disapproving of it.
Step-by-step explanation:
In the 8th and 9th centuries, Rome and Constantinople, the two seats of Christianity entered a diplomatic conflict on a religious base. The conflict arose from a seemingly harmless thing - the people and religious objects under the rule of Byzantium started to use artistic works of Christ's life. This was seen as something very nice by the general public in Byzantium, but Rome had different views.
The religious authorities in Rome were furious by this, and it was seen as heresy. Rome immediately tried to impose itself over Constantinople and to make it stop this, but the authorities of Constantinople stood their ground and supported this move. The end result was the formation of two different branches of Christianity, Eastern Orthodox with a seat in Constantinople, and Catholic with a seat in Rome.
