I am a child of the American Restoration Movement. That comes with many treasures and much baggage. While I'm not really into the "restoration" of forms with no regard for cultural context anymore, the very Biblical concept of "restoration" has captured my heart.
The main theme that runs through the vast majority of Jesus' teaching (and life) as well as the remainder of the New Testament (not to mention the Old Testament) is an idea he referred to as "The Kingdom of God" (also, synonymously as "the Kingdom of Heaven") This does not refer to a place you go after you die, but rather to the reality of God's real and actual reign on this Earth as it is in Heaven (the realm of God). You see, there was a time when the two were in synch, but mankind made a choice that disrupted it. It is important to note that this disruption was not just between individual people and God, but rather had ramification that affected the relationship between all creation and God (read Romans 8). Since that time, God has been in process to bring the two realms back together, in line and in synch with each other. Does this involve the salvation of individual "souls"? Of course! But, it involves so much more than that. You see, the church is meant to be a catalyst for the Kingdom of God. One of the main purposes for its existence is to be catalytic in God's Kingdom coming and His will being done "On Earth as it is in Heaven". That's why (if you read it right) the first chapter of the Bible and the last chapter look so surprisingly similar. That's why, in Revelation, you find Jesus saying things like "Behold I am making all things new". It's because God never gave up on His project. He isn't just killing time until one day when He's gotten tired of it all, He pulls all the people who believed the right things off of the failed planet and destroys it. He intends for this earth He created to be what He has always planned for it to be. If you remember, when He created the Earth, he thought it was "good".
You see, the church's role was never intended to be defensive. Our mission is not to just believe the right ideas, convince others of the right ideas and defend those ideas against all challenges. The goal is not to simply "restore" the structures and forms of the church in another time and culture and then maintain it. The mission of the church (and consequetially the Christian) is to be catalytic in the restoration of all things to God's dream for them. That's a "Restoration Movement" that I can get behind.
