Mark Hanson just convened the first plenary. BTW, they are making a big deal of this being the 25th anniversary of the ELCA. There is a large display depicting the highlights (in someone's opinion) of each year. He's just announced that worship as well as plenaries will be livestreamed this year, so if you want to catch the worship, you can do so. Then you won't have to believe me.
Odd opening prayer:
Since Abraham and Sarah,
since Mary and Paul,
since Luther [must mean Katie] and Muhlenberg,
since 1987 in Columbus,
We gather to you, O God.
The good bishop has muffed a few things in the opening liturgy--words misread, failure to recognize lines intended to be read by the congregation. Then he had everyone sit down before the last song, and seemed ready to cut the song entirely. The musicians forged ahead, however, and he had everyone stand up again.
