He was preaching a Sunday sermon...
Would you ask that he not be “overtly preachy” in that context?
Would it help if he just quit the pulpit?
I have no problem, personally, with his theological perspective. It’s Christianity 101, and to be expected.
The problem, however, is he is also Republican lieutenant governor candidate who happens to be a preacher and fits the false belief so unfortunately common in Jewish circles that “conservatism” and “Judaism” are mutually exclusive.
