Exegesis and Doctrine
The relationship between text, exegetical examination, theological discussion, and doctrinal system was not only easily established but was also assumed as an underlying principle of interpretation itself. Even those exegetes who, like Calvin, did not include loci in their commentaries, still assumed that the right exegesis of a text would yield doctrinal topics and that those topics could be developed into a coherent body of Christian doctrine.
