One of the more interesting things that I am discovering in my study of the Reformers and the post-Reformation scholastics and orthodox is that the earlier Reformers speak more freely about sacramental grace, while at the same time speaking much less of the role of works in justification. The exact opposite occurs in the later Reformed doctors. They qualify the sacraments greatly, yet also speak much more often of the necessity of good works in our salvation, even positing double justifications and evangelical law-righteousness by which we will be judged.
Neither of these is wholly wrong, but I do find it interesting that those who spoke most broadly about faith alone also spoke most freely of sacramental grace. The Sacraments were not for them “works,” but rather free gospel. It is as folks began to be more concerned with the finer details of the ordo salutis that the ordinary role of the sacraments seems to be diminished.
