The document discusses principles of biblical interpretation, including the analogy of Scripture principle. This principle states that scripture should interpret itself by comparing different passages on the same topic. Obscure passages can be understood by clearer texts, and comparing scripture with scripture allows us to find the deeper meaning. The principle also helps solve controversies and disagreements. A second major application is the typological principle, where the analogy of Scripture is applied to the relationship between types and anti-types in the Bible. Context is also important to understand what the text meant to the original audience.
