During conversation among white Christians, throwing out a quote from the Bible is welcome at any time. Regardless of the topic of discussion, a little bit of memorized scripture is always appropriate. While expert-level white Christians will execute their Bible quotation flawlessly, most white Christians are too far removed from Sunday School to be able to cite chapter and verse, or even remember the exact phrasing.
Instead, they will start with "Like the Bible says..." and then offer up something that sounds vaguely familiar and Bible-ish to the other church-going people in the vicinity. These Bible-quoters knows they are mangling the verse, but as long as they can muster at least fifty percent accuracy, the others will nod approvingly.
The Bible is the ultimate authority, so citing scripture is the perfect response to any problem or question raised in conversation with others. A half correct Bible verse has at least some words that are in the Bible, surely this is better than saying something that isn't in the Bible at all.
