Hi Morgan!
The first difference is relates to the Pope. For the Roman Catholics, the Pope is infallible; he can contradict lower ranking church leaders. On the other hand, Greek Orthodox believers consider a ‘highest bishop’, also known as the ‘first among equals’. This bishop is not infallible and does not have supreme authority over the churches.
Eastern Orthodox priests are allowed to marry before they are ordinated, while in the Roman Catholic Church, priests cannot marry.
Your answer is D. 100% sure
wish you the best of luck buddy!
