It doesn't seem like Bushie's Bible study is teaching him very theologically sophisticated interpretations.
"Interpretations"? You have read what this literalist church is like?
Yes. They lie to themselves and others about their interpretations being interpretations.
There are a number of stories in the Bible that genuinely do teach or purport to teach the lesson of submission to God's commandments. To try to apply the same lesson to
every story in the Bible, especially one as challenging--as easy to interpret in pat and glib and compassionless ways and as rewarding not to--as Mark 14, smacks
at best of laziness.
