◉ The Circumvention Taxonomy: Infinite Worth, Divine Fiat, and the Failed Escape Routes of Penal Substitution

Penal Substitutionary Atonement (PSA) is often presented as the point where divine justice and mercy meet: human wrongdoing merits punishment, an innocent Christ undergoes the punishment in humanity's place, and the guilty may therefore be pardoned without justice being relaxed. The difficulty is not merely that the arrangement sounds severe. The defining claims pull against one another. If penal desert is personal because it is grounded in an agent's wrongdoing, another person's suffering does not automatically discharge it. If the assigned penalty is death, exclusion, or endless separation, finite suffering followed by resurrection does not automatically complete it. A defense therefore needs both a transfer bridge and a completion bridge. This paper applies a preservation test to the principal repairs defended in historical theology and contemporary analytic philosophy. Infinite worth changes the value of the substitute without identifying the penalty completed. Imputation declares a new legal status without transferring the historical agency that grounds desert. Vicarious punishment, covenantal representation, corporate identity, voluntary consent, and union with Christ can explain authorization or association, but not by themselves the extinction of another agent's culpability-based liability. Divine fiat, pardon, commutation, and lesser-penalty acceptance can release the guilty, but they do so by relaxing or replacing strict penal satisfaction. Mystery and category-error replies withdraw public explanation; proof texts and tradition underdetermine the mechanism; resurrection confirms a successful outcome only if the disputed satisfaction is already assumed. Hybrid accounts may be coherent precisely insofar as they cease to make penal substitution do the decisive explanatory work. The result is bounded but severe. The audit does not prove that no future penal theory could state and defend the missing bridges, nor does it reject non-penal interpretations of the cross. It shows that the familiar circumventions do not simultaneously preserve personal desert, innocent substitution, penal satisfaction, and completion of the stated penalty. Evasion is not explanation, and a doctrine does not become coherent merely because every abandoned premise receives a devotional synonym.
