Here is an example of a thought that put a crack in my faith: Is our God one who does things by fiat, that is, by command ("Let their be light") or one who is hands-on?
In Genesis, both types of a deity are described. There is the god I have described as above, and the one who, in Genesis 3, walks about the Garden, seemingly doesn't know where Adam is, and fashions our first parents a pair of clothes by his own hands.
Now, the Mormon answer may be that Elohim does the ordering, Jehovah does the acting. But does that jive with textual criticism? I don't think so.
