While Kate Kelly's former church leaders meet in Virginia on Sunday night to decide if she will be ousted from her church, the founder of a prominent Mormon women's group will hold a vigil in Salt Lake City along with hundreds of her supporters.

Kelly has decided not attend the disciplinary hearing in her former congregation. Instead, she has sent in a letter she wrote and about 1,000 letters from supporters.

It's unknown when Kelly will be notified of the decision, but she could find out by email Sunday night.

She was shocked to find out earlier this month from her bishop that she is facing excommunication from The Church of Jesus Christ of Latter-day Saints, of which she is a lifelong member. The leader of Ordain Women is accused of apostasy, defined as repeated and public advocacy of positions that oppose church teachings.
