Let not God speak with us, lest we die.

Republican Christians are like the Israelies when Moses came down from the mount (Exodus 20:18_21).  They were afraid so they asked that God not speak to them directly, but rather He speak to Moses who could tell them what He said.

For all their talk about the Bible, Republicans rarely read it outside of proof texts and printed "Bible studies" and, rather, expect their preachers to read the Bible and tell them what it says.  Unfortunately, too many of these preachers have been hirelings  with an agenda and have twisted the message to their profit and their flock's loss.
