That phrase is getting thrown around a lot at the Assembly. People on all sides of all issues want to say that they represent the will of God and the true message of unity from scripture. I don't presume to know all of that, but I can't help noticing that the Creed is being used as a point of debate (or even attack). It's to be ready for such serious debates that we must study scripture and apologetics. We must be firm in our own faith, fully grounded in scripture and understanding. We may have different understandings, but at least we should be arguing from an informed and open-minded position that would make John Stuart Mill proud.
One blogger whom I respect (but disagree with) is Pastor Zip. Check out his take on Assembly issues at this link.
You might also be interested in Mark Hansen's Monday afternoon sermon. It's generally non-controversial, but just as I think it's important to hear multiple musical styles from multiple sources, it's good for the soul to hear or read different sermons and perspectives. The Assembly should feature some of the best preaching around, so keep checking back for more examples.
