A summary statement on the church

I often times marvel at what a radically different paradigm the Orthodox church operates than does the Protestant world.  The way we think about God, man, sin, the fallen nature, repentance, redemption, sanctification, eternity, etc. are all vastly different.
With this in mind, I thought I would create a summary of where we are coming from.  This is definitely not an argument, just a brief summary and also not exhaustive.
Since Christians are always interested in worship, I thought I would focus on the nature of church.
Christianity started in Jerusalem.  Jesus completed his work on the cross then, resurrecting, met his disciples and blessed them to carry on his work.  The church was centered in Jerusalem then moved outward to Antioch, through Asia Minor, then Rome and further outward.  This is all detailed in the book of Acts.
Churches were started and led by the apostles and those appointed by them.  This has been happening since that time.  An apostolic line has been drawn down through the ages, throughout all nations, all of the time handed down, all led, directed and protected by the Holy Spirit. 
The important point to see here is that the concept of church, and, more importantly, the objectivity of the church, is a temporal, physical reality.  The church is not just an idea.  It's not just an ambiguous, vaguely defined, inarticulate gathering of people who in some way call themselves followers of Jesus Christ. The church is a concrete reality, in space and time, held together and protected by the Holy Spirit.  This objective reality of "church" is what Jesus started and is what the apostles have handed down to us.  The church is what it always has been, the gathering of God's people, worshipping the Trinity through the Divine Liturgy by the guidance of the Holy Spirit.
The church is the Eastern Orthodox Church.
