It is constant and seemingly inevitable. Quite the contrary. It takes all kinds to make a church. The glue holding you together is not a uniform opinion on the practice of faith nor an identical stance on public issues. Your unity depends not upon unanimity of affection or strict concurrence on doctrine.
Love finds itself tested in all human circumstances, most especially in the church.
In a large urban congregation, he says, your church attendance patterns will differ, your prayer styles may vary, your ways of service will be dissimilar, your ears may be deaf to one another's religious language. But that is not enough to divide you. What holds us together is not so much a simple religious compatibility. What holds us together lies in our conviction of a Divine love that will never let us go no matter how stupid and wrong our own religious opinions, thus making it possible for each of us to treat one another as God has treated us, living in tension, to be sure, but never, in the name of the Gospel, writing one another off, always, as Paul writes to his Roman friends, always welcoming one another, expecting to gain a new friend, open to hearing a new truth. I love it because it reminds me of that church in Rome.
