You don't have to move very far beyond the confines of your own local church to discover that questions of how and why evangelicals relate to each other are rife in the UK at the moment. And even whether we should (of COURSE we should. Jesus prayed that his followers would be one).
It doesn't take long to come up against thorny issues like preferred worship styles, matters concerning the Holy Spirit or questions of leadership and gender. Nor long to meet people who assume that those who disagree with them always and necessarily hold a weak view of scripture.
It doesn't take long to find people who are clearly evangelical but who express it in some quite different ways to me, and therefore to talk past each other or find it impossible to work together simply because we spend too much time in our own silos and just don't get each other
