Personally I have never met an ordained preacher/priest who is a female. I did attend a Lutheran wedding once that was performed by a woman. I do not know what her title was/is, all I remember she liked to talk and talk a lot.
Like I said I do not know anything about this event and will have to take others word the purpose was to take a slap at Catholics.
Must be ELCA. Those folks have been spending too much time with the Episco-pagans. I'm Missouri Synod Lutheran. We're old school all the way. It's very refreshing for a former Episcopalian.
