" The Finality. In historical polemics this feature of the atonement has been urged against the Romish doctrine of the sacrifice of the mass. This polemic against Romish blasphemy is just as necessary today as it was in the Reformation period. The atonement is a completed work, never repeated and unrepeatable. In our modern context, however, it is necessary to insist upon this tenet not only in opposition to Rome but also in opposition to a viewpoint prevalent within Protestant circles. "
