While we often benefit from the insights gleaned from the world of religious books, the Bible itself is the only real standard of religious thought and practice. All else is to be measured by it.
All theological opinions of men, all human traditions passed down to us from our forefathers, and all cultural trends of modern society are irrelevant.
No one is bound by any man-made confession of faith, manual of church order, or book of church discipline. The Bible alone must govern our faith and practice.
