The main idea here is how the truths of the Faith fit together in a coherent whole and within the overarching plan of Revelation. The term Analogy of Faith captures this precisely: it is the principle that each Christian truth must be understood in the light of the whole deposits of faith, so that no doctrine contradicts another. When parts of Revelation seem difficult or unclear, we interpret them in a way that preserves harmony with the clearer, foundational truths already given; the whole faith guides the interpretation of its parts.

This emphasis on mutual coherence—interpreting one truth by the others and keeping the entire Revelation in view—is what sets Analogy of Faith apart from more generic phrases like Harmony of Doctrine or Consistency of Belief, which don’t name the specific hermeneutical method or the integrated plan of Revelation. Unity of Revelation is related, but the established term for this interpretive principle is Analogy of Faith.
