I have spent a number of years engaged in Jewish-Christian dialogue. More recently, I have been involved in extensive exchanges with Muslim scholars. I regularly visit Utah for off-the-record discussions with Mormon leaders about deep disagreements between Mormons and evangelicals. I approach all these conversations with great enthusiasm. And yet I have found myself regularly breaking into a cold sweat at the thought of engaging in dialogue with fellow Presbyterians about homosexuality. Why the anxiety in this case?
