We reordered our church about 15 years ago.
It was a painful process as so many people were attached to the pews and other fixtures that perhaps their ancestors had contributed.
We have almost doubled our congregations since the reordering. We had to split our main congregation into two during the reordering in order to fit everyone in the church centre. One of the services became more traditional, and the other more modern, compared to the hybrid we had before. On moving back into church, both congregations had room to grow.
We both restored our church to its original Georgian architecture (bright and airy compared to gloomy Victorian), and totally modernised it too - carpets, underfloor heating, state of the art audio-visuals, and basics like disabled access and toilets.
Because we have chairs instead of pews, we can use the building far more - and do. We are happy to let the building out for concerts and we are not precious about any stuff (except the tech desk). We are happy have them move the communion table, for example.
We firmly believe that the church is the heart of the community and we have lots of mission projects that anyone can benefit from - free cafe, food bank, debt counselling, help accessing benefits, parenting courses, toddler group, holiday club, and more.
I don't think the CofE is dying. Far from it. The harvest is more plentiful today than ever. The Victorians did us a big miservice by building massive churches (bigger than their needs) in inappropriate places. Town centre churches are not that useful when most people live in suburbs. There are lots of vibrant CofE churches making church plants in the heart of modern communities.
