A.W. Tozer emphasizes the significance of Christ's one-time sacrifice, which has ongoing effectiveness for the forgiveness of sins, contrasting it with the repetitive sacrifices of the Old Testament priests that could never truly atone for sin. He highlights that through Jesus' sacrifice, believers are made perfect forever and that no further sacrifices are needed for sin. Tozer argues that the notion of a perpetual sacrifice undermines the profound nature of Christ's atonement and is a serious error in understanding biblical theology, particularly in relation to Catholic beliefs. He calls for a compassionate correction of these misunderstandings rather than mere tolerance.
