In Dublin for the meeting of primates, Presiding Bishop Katharine Jefferts Schori preached at Christ Church Cathedral Sunday.
Let the photographic record show that at some point, she wore her mitre. 
Here’s a bit of her sermon:
We already have a cosmic savior, yet those who share God’s dream are all partners in healing the world. God can’t do it without us. As Desmond Tutu is fond of saying, when God said feed the hungry, he didn’t mean to stand around and wait for pizzas to fall from heaven.
Sometimes the partners in healing end up sharing Jesus’ road to Calvary. An Anglican was murdered in Uganda this week, a man who has been a strong voice for the basic human rights of gay and lesbian people. His voice has been silenced. We can pray that others will continue that work, or be challenged by the brutality of his death into some conversion of heart. Will we challenge the world to respect the dignity of every single human being?
The healing of the world needs the participation and leadership of all parts of the body of Christ. It starts with urgent voices, and changed hearts, our own conversion, and our challenge to systems that perpetuate all kinds of sickness and death around the world.
Saviors and leaders are all around us – in these disciples of Jesus, and in similar communities far beyond this one. When we came to the baptismal font, each one of us was presented and dedicated to God to share Jesus’ healing work. We’ve shown up here today to be fed and encouraged for that ancient work of healing the world.
