The most prominent Regular Baptist group is the General Association of Regular Baptist Churches. While the term "Regular" "Baptist" was originally a reference to the Particular Baptists, it came to be used more loosely as a synonym for "orthodox". The "Baptist Bulletin" of the GARBC defines them simply as groups who believe "orthodox, Baptist doctrine" and "affirm the rule or measure of the Scripture." As compared to General Baptists or Free Baptists, Regular Baptists were strict in their beliefs, and therefore also called Strict or Hard-shell Baptists. To be a Regular Baptist church in the GARBC is to hold to distinctive baptistic ecclesiology and interpret the Bible literally.
