There are churches out there like that. I feel like I attend one. People feel safe to talk about anything - including their shortcomings. Everyone in our church is flawed; and admits it. We share problems with ourselves, our spouses, our kids, our besetting sins, etc. It's called being "broken together"; and results in openness and willingness to call out for help when needed. Sometimes praying for ourselves and others takes longer than the sermon. Some people who visit are uncomfortable with such openness - especially in an SDA church - and they don't come back. Others are drawn to it and stick around. one of our members is even on the board of directors of a non-denominational church that caters strictly to those with "sexual deviancy" issues (i.e LGBQT's, etc) who want to correct or reconcile their social deviancy with their Christianity.
I use the term "deviancy" not as a judgement, but as a term used by many conservative denominations as a reason to exclude these people from fellowship. It's the same for those who have chronic alcohol, drug, or tobacco problems.
I think some people confuse leaving "church" with leaving God. Lots of people find Christian fellowship outside of the confines of a brick and mortar church. I find spiriual solace with my brothers and sisters here at Adventistan. I probably spend as much time here as I do in my brick and mortar church.
