Failure of the “common good”
it’s actually rather hard to find Biblical support for ‘Christianity unity’ or the common good. John 17:21 ‘they all may be one’ is made to do an awful lot of work. There’s rather a deal more in Jesus’ teaching about hating father and mothers, and setting brother against brother. ‘Do not suppose that I have come to bring peace to the earth. I came to bring not peace but a sword.’
