"...that in this matter of religion the opinions and judgments of the parties might be heard in each other's presence; and considered and weighed among ourselves in mutual charity, leniency, and kindness, in order that, after the removal and correction of such things as have been treated and understood in a different manner in the writings on either side, these matters may be settled and brought back to one simple truth and Christian concord, that for the future one pure and true religion may be embraced and maintained by us, that as we all are under one Christ and do battle under Him, so we may be able also to live in unity and concord in the one Christian Church."
The key phrase that shows the difference between Augsburg (1530) and modern day "get along with anyone" Christianity, is this: after the removal and correction of such things as have been treated and understood in a different manner". When the possibility of seeing something corrected or even removed from the teaching and practice of the Church isn't even on the table, true progress has been rendered impossible. As C.S. Lewis stated, "There is nothing progressive about being pigheaded and refusing to admit a mistake." When we are willing to be corrected, then unity among Christians will have a chance. But not before.
