Actual human discourse happens within a number of contexts, not in some sort of unified public forum.
Rowan WilliamsI have, by God’s grace, learned as a member of the Christian community what is the nature of God’s mercy, which does not leave me to overcome my sin by my own effort, so I have something to say to the fellow-sufferer who does not know where to look for hope. And what I have to say depends utterly on my willingness not to let go of that awareness of myself that reminds me where I start each day—not as a finished saint but as a needy person still struggling to grow.
