Greater Precision
The inadequacy of the earlier codifications in themselves to deal with these issues is obvious from the very fact that such doctrinal deviations as Arminianism and Socinianism gained significant folio wings. The questions they raised about the principles of scriptural interpretation, the nature of God, and the content of salvation drove the Orthodox to greater levels of precision in their explication of Reformed doctrine in order to defend the tradition, and Owen was no exception to this general tendency.
