If you read through the comments here you will notice that all progresssives/liberals have their own individual ideas on how the Church should function, how it should be governed and what it should teach.
At the reformation the Protestants did exactly what you progressives are doing today with the result that there are now around 40,000 different Protestant sects throughout the world whilst the one, true Church soldiers on. It will continue to do so as you progressives argue, split among yourselves, fall away and set up your own particular churches.
Those who think they know how Christ intended His Church to function should look back to what happened in the 16th century when a lot of people thought they knew what Christ intended His Church to be.
