The Protestant Reformation brought forth the cry “Sola Scriptura” - that Christianity should be based on the words of scripture alone, not on Roman Catholic church tradition.

Peter D Williams of Catholic Voices argues that the reformers were wrong and that the ultimate authority for Christians rests in the three strands of sacred scripture, sacred teaching and sacred tradition. James White of Alpha and Omega ministries argues that the Catholic church has fallen into error, and that Christians should look to scripture alone for their doctrine.
