Analogia Fidei
The analogy of faith was not regarded as a “creedal grid” received by tradition and to be imposed upon the text of Scripture, but it was viewed as an extended use of the analogy of Scripture. In other words, one text of Scripture must not only harmonize with all other passages of Scripture, but its interpreters must also avoid reading a text in such a way that it contradicts the received body of doctrine that has been derived from Scripture.
