The Classic Studies on the Atonement collection presents many of the most important late-nineteenth- and early-twentieth-century studies on the atonement of Christ. Thanks to such notable authors as R. W. Dale, John Miley, Octavius Winslow, and David Smith, Classic Studies on the Atonement offers over 8,000 pages of interpretation, observation, translation, contextual history, and application on this important doctrine.

In On the Atonement and Intercession of Jesus Christ, William Symington defines the important terms that relate to the atonement: reconciliation, redemption, propitiation, satisfaction, substitution, vicarious, and expiation. He then attempts to answer the most common objections to the doctrine. Following the objections, Symington shows the necessity of the atonement by way of the perfections of God, the nature of moral government, and the testimony of the Scriptures themselves. He then exhibits the reality of the atonement by examining ancient and Levitical sacrifices, prophecy, the sufferings of Christ, the extent of the atonement, and more. The second part of Symington’s pivotal work examines the intercession of Christ. Here Symington divides the area of study into five distinct parts: the reality of intercession, the nature of intercession, the matter of intercession, the properties of intercession, and the results of intercession.
