I got a reply back from my stake president, and it looks like I'm not going to a church court after all.
It would be inappropropriate to quote the letter without permission, but I'll summarize as best I can. I really disagree with some of his points, which I'll address later.
He apologizes that my spiritual needs are not being met by the LDS church and that I felt I needed to join another church. Based on an interview we had a few years ago he expresses understanding that I have concerns.
Just disagreeing with the leaders or mere loss of belief is not generally a reason for having to hold a church court. Generally when people decide the church is no longer right for you, the right thing to do is to resign. He doesn't encourage that, but if I really feel the church is inconsistent with my beliefs and I'm unlikely to return, it's the best thing. A simple signed letter to my bishop will do the job.
Remaining a member of the LDS church causes others to need to seek me out. My baptismal and temple covenants still remain in force. This may not be what I want, but if I want to keep contact and would welcome attempts to reach out I can keep my membership in the LDS church, regardless of whether or not I am active.
Church discipline is reserved for situations where members openly defy the LDS church, such as publishing articles against the doctrines or leaders or attempting to lead others to adopt incorrect doctrines or leave the church. He doesn't feel this is what I'm doing, nor what he expects me to do.
This situation is my choice and he has no wish to force me, except he would want to keep my fellowship in what he firmly believes to be the church of Jesus Christ in its fullest form.
Regardless of what I decide, he wants to remain my friend and welcomes any opportunity to discuss my beliefs and spiritual journey.
He signs the note,
"Your brother in Christ, H____ M______, Stake President"
