Is the Bible sufficient for the spreading of the gospel and the working of faith in unbelievers? Are miracles and signs necessary for effective evangelism? This article answers these questions based on the story of the rich man and the beggar, as recorded in Luke 16:19-31.

This article looks at the relationship between the guidance of the Holy Spirit and the sufficiency and authority of scripture. It shows that the Holy Spirit uses scripture to illuminate our minds to God's truth, and that God does not give extra revelation to what we already have in scripture.

How did the doctrine of sola Scriptura feature in the centuries before the Reformation? This article shows how it was championed by the church fathers.

The article argues for the recognition of the slogan "sola Scriptura," which means that all authority for the church and the believer should derive from Scripture alone. The article thus argues that tradition cannot be taken as a reliable source of authority.

This article considers the sufficiency of Scripture, and gives thought to the difference this makes for the Christian life.

The doctrine of the sufficiency of scripture is rooted in understanding the Bible to be the inspired word of God. The Bible is true, since God cannot lie, and has authority. Therefore, it is the only rule of faith.

God gave us scripture to demonstrate His wisdom and love toward His church. Adding to or subtracting from the scriptures is a failure to uphold the sufficiency of scripture, and seeks to undermine God Himself.

This article is about the Reformers and their view of Scripture and the authority of Scripture in the reformation of the church. Sola Scriptura is also discussed.

This article discusses three misunderstandings with regard to Sola Scriptura: the idea of reformation, creativity and the work of the Spirit.

This article evaluates the modern gift of prophecy that the charismatic movement claims, in the light of the Word of God. It defines terms, speaks about how to recognize a false prophet, shows how charismatics rationalize fallible prophecy, and provides charismatic objections raised in response. It shows how the charismatic position is at odds with the sufficiency of Scripture.

Does God speak today apart from the Bible? The author addresses this question, entering into debate with those who believe that God speaks today, such as Jack Deere and Wayne Grudem. In the rest of the article, the author provides some definitions on both sides of the argument.

The author laments that what he terms "solo scriptura" is gaining ascendancy over the traditionally confessed tenet of evangelicalism, sola Scriptura. Solo scriptura is a teaching that is against the use of any tradition whatsoever as a source of authority in the church. Tradition, according to the author, touches on aspects such as creeds and the teachings of early fathers.

With the principle of sola Scriptura the Reformers restored what the church has always confessed. This article shows that from the early church this principle was upheld over against the Roman Catholic appeal to tradition as an authority next to Scripture.

Throughout the history of the church, heretics often protested against orthodox confessions on the ground of the so-called "non-scriptural language" of the orthodox creed. They pointed out that phrases such as “of one essence with the Father,” and “one substance with the Father” were not to be found in Scripture. Heretics often used the argument “no creed but the Bible” precisely so that they could use biblical language to evade biblical truth.
