I might add this is not the fruit of "emerging" though he recommends a Rob Bell book, it is solely the victory of Jesus Christ in a person's life as lead by the Holy Spirit.
Here is part of the letter...
"I came back into “church fellowship” through a man I met at a gay bar. He was actively gay at the time, separated, with one child, and deeply committed to his own walk with Christ. He and I never had sex. After several years, he became celibate and continued Christian outreach to gays. I was part of that outreach and had become celibate myself. I felt the Lord calling me to celibacy, at least for a time, after the painful breakup of the two “long term” relationships."
