I hadn't myself understood why I disliked one style of biblical quotations until I had to explain it to you.

Other reasons for biblical quotes are fine, such as showing how telling a story several times and differently has an effect, or showing something about how people then likely thought, or having an old source for "Nothing new under the sun", etc. There's nothing about the books that makes quoting them magically a bad thing to do, it's just that there's enough contradictory stuff (probably in Exodus or Numbers or Deuteronomy alone, much less the Pentateuch, much less the Old Testament, much less...) that saying there is Biblical warrant for something similar to one's position is the most unspectacular thing one can say. A quantity of quotes from among sources showing preponderant and/or broad and consistent would be something else and as valuable as perhaps a small quote from a dissimilar source, but by definition that's not something that fits in a reasonable amount of space and is more of a thesis paper.

The first sentence of this comment is the important one, we can probably constructively generalize from it.
