The sole basis of our belief is the Bible, composed of the sixty-six books of the Old and New Testament. We believe that Scripture in its entirety originated with God who inspired it through his chosen human instruments. Scripture thus speaks with the authority of God and at the same time reflects the backgrounds, styles, and vocabularies of the human authors. We hold that the Scriptures are infallible and inerrant in the original manuscripts and, when correctly interpreted, are trustworthy and fully truthful in all they teach. They are the unique, full, and final authority on all matters of faith and practice; there are no other writings similarly inspired by God. Proper interpretation requires applying the normal rules of grammar, and taking into account the literary context, historical-cultural setting, and the literary genre of each passage to be studied.
