I read this book for a Theology 1 Seminary class in the Fall of 2020. What an incredible insight into the nature of what the church is called to be. I loved the idea of thinking about the church as a mosaic, with the an individual existing as a single piece of the mosaic, the local church as a segment in the mosaic picture, and the global church as the entire image. When we look at the church this way, we see every individual Christ follower as an integral piece of the body of Christ, we see every local church in all it's denominational differences as a needed flavour of what it means to be the body of Christ, and we see the global church as beautifully diverse and unified across nations, cultures, theological groundings, and practices. To be ecumenical is to be diverse.
