Allen delivers a work of classical Reformed theology. He irenically differentiates the Reformed position on sanctification from some Lutheran positions, through careful biblical exegesis and retrieval of Calvin, Augustine, Berkouwer, and others. From a more traditionally Reformed perspective, Allen here inherits the mantle of John Webster. As a Catholic, I am deeply grateful for Michael Allen's vision, with the ecumenical conjunctions that it reveals.
