My Institute teacher

I still don't know his name. But he has a Canadian accent.
He often says very strange things, but no one seems to notice. Here are a few:

• If you notice a baby with a dirty diaper, it is unconditionally your responsibility to change it.


• Without the atonement, our bodies would not be able to heal.


• Olive oil is pure.


• Nephi had a girlfriend.


• We should rampantly speculate about what happened during the vision of the Tree of Life.


• The daughter of Ishmael who pleaded with Laman and Lemuel probably married Laman or Lemuel.

Am I alone in considering these things rather strange and unsupported by the scriptures?
