This week, the leaders of the Presbyterian Church in America will gather in Richmond, Va., for their annual General Assembly. The Presbyterian Church in America is a small, theologically conservative Christian denomination that was my family’s church home for more than 15 years.

It just canceled me.

I am now deemed too divisive to speak to a gathering of Christians who share my faith. I was scheduled to speak about the challenges of dealing with toxic polarization, but I was considered too polarizing.

I was originally invited to join three other panelists on the topic of “how to be supportive of your pastor and church leaders in a polarized political year.” One of the reasons I was invited was precisely that I’ve been the target of intense attacks online and in real life.

The instant my participation was announced, those attacks started up again. There were misleading essays, vicious tweets, letters and even a parody song directed at the denomination and at me. The message was clear: Get him off the stage.

And that’s what the conference organizers chose to do. They didn’t just cancel me. They canceled the entire panel. But the reason was obvious: My presence would raise concerns about the peace and unity of the church.

Our family joined the P.C.A. denomination in 2004. We lived in Philadelphia and attended Tenth Presbyterian Church in Center City. At the time, the denomination fit us perfectly. I’m conservative theologically and politically, and in 2004 I was still a partisan Republican. At the same time, however, I perceived the denomination as relatively apolitical. I never heard political messages from the pulpit, and I worshiped alongside Democratic friends.
