This viewpoint has come under attack as of late. Here is a good “definition” from CARM:
- Penal Substitution is a theological viewpoint within Christianity that maintains Jesus was legally punished in place of the sinners. That is, He took the place of the sinner. It is “penal” in that Christ suffered the penalty of the Law, taking the “penalty” of the Law. It was substitutionary in that Christ took our place on the cross when He bore our sins (1 Pet. 2:24) and became sin on our behalf (2 Cor. 5:21)….. Though there are varying views of the atonement, the Vicarious Substitutionary Atonement (Penal Substutionary Atonement) best explains the Scripture and most importantly, it probably relates the satisfaction of Law as a relates to the holiness of God.
