Denominational "Free" Churches?

I have become a regular follower of Mac Frazier's blog. He is working in a denominational setting, but check out this reflection from his most recent post, Reflections on Charter Day 2009, looking at what the founders of his denomination did and meant to do and whether those same characteristics are still present in the denomination today:

Creating institutions and planting churches are selfless acts. These things take sacrifice and hard work that can never show a “return on investment” for those who do them. And now, how can we repay those who gave us what we have–the Academy of the New Church, the General Church of the New Jerusalem, and New Church congregations scattered across the world? All movements fade in time, and successful ones leave behind communities, institutions, and other organizations. Our churches and schools are good things, gifts from the Lord through the agency of people no longer living. I believe it is time to “pay it forward”–to recognize what we have freely received and find new energy for passing even more on to the next generation, and to the larger world around us. It is time for a NEW movement.

So my questions are: Is it possible to found a free church movement inside the shell of an existing or failing denomination? Are the communities, institutions, and organizations left in the wake of a failing movement an opportunity or a threat to a new movement? Can the assets and good will of a fading denomination be given freely to an independent church or will the free church become dependent and so denominational because of it? Or if a church is started inside the umbrella of a denomination with the intent of being a free church, will that vision ever be realized?

I believe that churches and the movements that build them need to start as they intend to continue. In other words, plant the church free and it will be an independent and local-only church integrally tied to the life and walk of faith of its membership and local community, start a denominational plant and it will be a local branch of the denomination and serve the denomination first and its members and community second. Free churches are free to be focussed outward and to spend their time and resources on the mission of building the body of Christ. But with the weight of preserving the greater institution of their denominations, are local denominational congregations (that remain in their denomination) as able to serve the mission of Christianity?

What do you think?
