The Roman Catholic Church thought that the icons helped them pray to God and to worship Him. The Eastern Orthodox Church thought that this was not the way to worship God. they thought this because of the Ten Commandments, that they were idolizing the icons over God.
The Eastern Orthodox forbid icons, where the Roman Catholic Church use figures of Mary and saints.
Explanation:
Icons played a significant role in the disagreement between the Eastern Orthodox Church and Roman Catholic Church. The split happened when Constantinople declares its Eastern Patriarch and a separate church. Icons cause controversy among the people because of their different faith and believe. Pope Leo IX came to Constantinople to meet the patriarch to solve the dispute of religion but both excommunicated each other.
