Name three principles of “the analogy of faith.”

The Reformers’ “analogy of faith” rests on what the Bible says about itself: first, the Bible can be understood — a loving God communicates clearly, so we explain obscure passages by clear ones; second, the Bible is progressive revelation — the message unfolds more fully toward the end, so we read the Old Testament in light of the New; and third, the Bible does not contradict itself — apparent contradictions yield to careful study.
