One of the speakers quoted at some length a 1930 letter from Evelyn Underhill to the Archbishop of Canterbury in which she reminds him that—this is close to a quote—the really interesting thing about religion is God. The speaker noted the irony that she felt the need to remind the Archbishop of this!
A second point on which the speakers agreed was that Churches can help people to know God better in part by promoting daily spiritual disciplines. We come to know God better if we are spending regular—ideally daily—time in prayer and Bible study. Regular attendance at worship helps.
I would add, and I am sure they would agree, that living lives of service helps. Practicing forgiveness in our relationships helps. But I am grateful for what I heard as a call to return to the classic spiritual disciplines. If our Churches can facilitate that return, they will flourish. More to the point, they will deserve to flourish because they will be doing what they were formed by God to do. May it be so.
