There is the view I call penal non-substitution, or the penal example view. (It is also called the Governmental View in textbooks of theology.) This is often associated with Arminian theology stemming from the great Dutch jurist Hugo Grotius. However, the view was taken up by [Jonathan] Edwards's disciples in New England, who developed a Calvinistic strand of the doctrine.

[John] Calvin is often identified with his account of predestination. Yet that appears in the third book of his Institutes, not the first.

[Jonathan] Edwards definitely shows up in the book [Saving Calvinism]. He appears as one of the interlocutors in the chapter on free will, the other being the Southern Presbyterian theologian John Girardeau.

Jonathan Edwards developed a Calvinistic strand of the doctrine.

In the twentieth century the Reformed tradition was developed in several ways including additional confessions (Barmen, the Belhar Confession, the 1967 Confession of the PC(USA), and so on). It was also significantly augmented by the work of important thinkers like Karl Barth, T. F. Torrance, Jürgen Moltmann, Emil Brunner, Kathryn Tanner, and so on.

The atonement chapter [from the book Saving Calvinism] shows how there are real riches in Reformed theology that most Christians today have no idea about.

[John Calvin's] treatment of the person and work of Christ, of the Holy Spirit in the life of the believer, of prayer and liturgy, of the sacraments, and of the way in which we have an in-built sense of the divine that we suppress to our great sorrow - these are all immense contributions to Christian thought. The same could be said of his commentaries, which are still regularly consulted by biblical critics today.
