The Summa Theologia - The Mystery of the Faith

When saint thomas aquinas approaches the mysteries of the faith in the summa, he does so in orderly fashion. He arranges them in questions, and in those questions are articles. And so it's common to talk about arguments as articulated, or even joints as articulated because we see how one thing hinges upon another. So you'll hear different voice in the tradition speak about the analogy of faith. It's used as a way of describing how certain aspects of the faith have a kind of primary place in our contemplation.
