Wes, part of the problem with your reasoning is that EO doesn't have a pope.
They do have bishops, and I believe the Most Reverend is the "first among equals," right Bizzy?
Actually, Bizzle, there are several things that are in common between RM and EO. However, the big differences are communion of saints, communion/Eucharist, and the hierarchy in general (although EO churches are autonomous, their structure is very different).
For example, Main Street Church of Christ in Anywhere, USA hierarchy might look like this:
Elders (a group of men in the congregation shepherding the church)
|
Deacons (typically a group of men who do work in the church- usually men who have younger children, as those with older believing children become elders
)
The Ministry team has input into the church, but the elders are usually the final authority.
Communion- Eucharist
RM does not teach transubstantiation- which I believe EO teaches, yes? Correct me if I'm wrong here.
Communion/the Lord's Supper represents Christ's body and blood.
Those are just some at the top of my head.
