Simon, a reasonable perspecitve, but arguably is it the church that have responded to create a new movement - as you opined - or could it be genuinely God, the one building the church?
Surely the last five hundred years is a long time to have the church autonomously creating such movements without God's input and/or approval? In fact, I believe they are part of the outpouring of the Holy Spirit until he returns. The problem is, IMO, each time God moves (if I could call it as such), we as people try to put him into a box and won't allow God to continue.
I also believe, that whatever we end up calling these things - waves, movements, renewals etc - is restoring what we've lost and moving us closer to the Kingdom of Heaven coming to earth.
I'm not saying that every movement of the last 500 years was entirely man made and had no annointing.
What I am saying is, everything truly NEW in the church since its birth in the new testament has been man made. If you look at the movements of the last 500 years they have all been in response to problems within the church. They have been in response to abuses, or to hypocrisy, lack of holiness etc.
The point I'm getting at is the remedy to these problems have never been new... they are not things that the church has never had before. The church, from its founding has had everything it needs.
The gifts of the Spirit are a good example. The church has always had the gifts of the Spirit from the very beginning. There have been times and places when the gifts were not made use of, and the indwelling of the Spirit was not taught, nor practiced. Never the less, the Holy Spirit has always been in the church since the beginning, and the gifts have been available to us from the beginning.
The movements that have come over the last 500 years have undoubtedly been the result of the Holy Spirit dealing with the problems that arise in the church. However, every new thing that has arisen out of these movement has been added by man and often times the result of either impatience, or selfishness, or lack of faith.
I believe that God has given the church authority which includes some latitude in issues such as organization and logistics and even styles of worship. Thus it is possible that there could be subtle changes over time depending on what the circumstances warrant. However that authority is limited to within certain parameters that God established.
Anything new which is outside of that authority is not of God, it is man made.
