Doctrine in Development examines the imputation of Christ's active obedience with attention to the thought of Johannes Piscator, who denied it and so provoked the arguments that settled it.

Challenging earlier scholarship that treated the doctrine as plainly present in the Reformers, Heber Campos shows how Piscator's exegetical and theological objections generated responses which drew several other doctrines together in its support. A study in how confessional precision actually comes about.
