One of the sects of Christianity that is on the rise, especially within the Evangelical branch, claims that the sole religious authority comes from Scripture, and the traditions, doctrines, and interpretations of man have no authority. Martin Luther was perhaps the most famous person to preach sola scriptura, the idea that the Bible is the sole source of religious truth. However, I argue that it is impossible to hold to the idea of scripture only with logical consistency. The reason is simple; the determination of what the sacred writings make up the Bible is wholly extra-scriptural and based on church tradition, doctrine, and politics. In order to logically hold to scripture only, one of the writings in the Bible would have to have a list of all of the books of holy writings, including itself; otherwise, one must go outside of the scriptures themselves to determine the which writings should be in the Bible, which renders the claim of "scripture only" false. Since this list does not appear in the Bible, any claim of authority based on scripture alone is facially false as the identity of scripture itself is based merely on tradition, doctrine, and church politics, which are the works of humankind. In order to support scripture, Christians must appeal to doctrine, thereby abondoning their imagined authority of God-breathed scripture.
