How did the word bible belt come to be?

Answer 1

The southern portion of the United States, traditionally contained, and to this day contains pastors who teach biblical text to church goers. In Northern church systems, most are structured like the Catholic church and do not teach biblical text. These structured church systems teach from the book of common prayer and weekly sermons, expounded upon by the priest. Therefore the people who learn from traditional, southern church pastors are very knowledgable of the biblical text.
