I didn’t see this answered but there’s lots here so if someone answered it, I apologize for the duplication.
The heads of Orthodox churchs are called Patriarchs. At one time the Pope of Rome was “First among equals” and participated in synods with the other Patriarchs. When the great schism of 1053 occurred this obviously changed as now the “Pope” and his followers considered his role to be different than the other churches believed.
Orthodox people as a general rule will not give you a “verse” to prove or explain any point of theology. We believe you must take the entire history of the church in context. We are equally based in both Word and Tradition as has been mentioned. The two together are like your right and left hands. It’s like playing guitar, you can’t play without using both hands.
We do believe the wine and bread become the body and blood and this is what we take at communion. We don’t believe they literally become body and blood so, no, you won’t see clots and flesh in the cup. This is one of the mysteries of the church.
We use the word mystery a lot. There are things we don’t pretend to understand. How can mere men understand God?
And as a general rule we are not presumptuous enough to think we are the judge of any one. We know that God is the final judge and you will not be judged until you are in his kingdom, so we would never ever presume to tell another being that they were damned.
We also don’t believe you die and immediately meet God. We believe when people die they are ‘asleep in the Lord’ and that we will all be judged when the time of the kingdom is at hand.
We’ve had a few home schoolers at our church but most folks wouldn’t think of it. Most of the folks in our church who have home schooled were converts, not cradle orthodox. There is one cradle orthodox family that I know of that’s home schooling, and at this moment they are the only ones.
Things to know when you come to our churches: We are pretty conservative in our dress. We expect you to dress appropriately. No tight pants, halter tops, deep necklines, etc. Women generally wear dresses. Don’t worry about head coverings as the folks will generally recognize you’re a visitor. We do cross ourselves at appropriate moments, but don’t expect you to. If you’re in a church with pews just stand and sit when everyone else does. When in doubt about what to do, stand. It is never inappropriate to stand in an orthodox church. Don’t cross your legs. Do not attempt to take communion, but you may approach the chalice and ask the priest for a blessing. At the end of services everyone is welcome to approach the cross the priest is holding and kiss it, and take holy bread. However, we are not offended if you choose not to do this.
While the Catholics have welcomed orthodox to take communion at their churches for several years, we do not reciprocate in this practice. We also as a general rule don’t take the Catholics up on their offer. We may not take communion any where other than an Orthodox church except in most dire circumstances. The reason for this is very simple: we are not in communion with each other. Note that we are not in communion with all other churches that call themselves Orthodox, either.
The Antiochian church has eastern rite churches and western rite churches. The western rite churches are primarily parishes that were formerly episcopalian, catholic, or others that have converted to our canon law and theology but are still using their same services. Sometimes this gets confusing, even to us.
