The aim of the historical-grammatical method is to discover the meaning of the passage as the original author would have intended and what the original hearers would have understood. The original passage is seen as having only a single meaning or sense. As Milton S. Terry said, "A fundamental principle in grammatico-historical exposition is that the words and sentences can have but one significance in one and the same connection. The moment we neglect this principle we drift out upon a sea of uncertainty and conjecture."
