Eastern Orthodox – Roman Catholic theological differences

Eastern Orthodox and Roman Catholic are two types of Christianity that have some differences in their beliefs and practices. These differences date back to the Great Schism of 1054, which divided Christianity into the Eastern Orthodox Church and the Roman Catholic Church. Here are some of the main differences between the two:

1. Authority: In the Eastern Orthodox Church, the highest authority is the Patriarch or bishop of each region, who makes important decisions about doctrine and practice. In the Roman Catholic Church, the highest authority is the Pope, who is considered the supreme leader of the Church and has the power to make decisions on behalf of all the bishops.

2. The role of the Holy Spirit: The Eastern Orthodox Church believes that the Holy Spirit proceeds from the Father, while the Roman Catholic Church believes that the Holy Spirit proceeds from the Father and the Son. This difference in belief came about over a disagreement about the wording of the Nicene Creed, which is a statement of Christian belief.

3. The use of icons: In the Eastern Orthodox Church, the use of icons (religious paintings or images) is an important part of worship. In the Roman Catholic Church, the use of icons is less common and some denominations do not use them at all.

4. Eucharist: Both the Eastern Orthodox and Roman Catholic Churches believe in the importance of the Eucharist (also called Communion or the Lord's Supper), but they have different beliefs about how the bread and wine become the body and blood of Christ during the ceremony.

5. Theology of sin: The Eastern Orthodox Church sees sin as a disease that needs to be healed, while the Roman Catholic Church sees sin as a legal violation that needs to be punished.

Overall, while the two churches share many beliefs and practices, there are some theological differences that have caused them to split from each other.
