Soteriology

Defines mediatorship (natural and moral), distinguishing it from Gnostic and Arian misconceptions. Proves that Christ alone is the natural Mediator between God and man (de fide — Trent, Sess. V), and that other mediators (priests, saints) are such only in a secondary and ministerial sense. Explores the Scholastic resolution of the paradox that God in Christ mediates between Himself and mankind.

§2 treats two questions. Congruity: the Incarnation was the supremely fitting means of redemption — it glorified God's justice, mercy, love, and wisdom simultaneously; the Second Person was the most fitting to become incarnate; man's nature rather than an angel's was most fittingly assumed; the virgin birth was congruous. Necessity: refutes absolute necessity (Wyclif) and absolute Optimism (Leibniz); shows the Incarnation was freely chosen; God was under no obligation to redeem; infinite satisfaction hypothetically demanded a natural Mediator.

The classic controversy: would the Incarnation have occurred had Adam not sinned? The Thomist position (held by Aquinas, Bonaventure, De Lugo, Petavius): the Fall was the chief motive — Scripture always assigns sin as the reason; Scotist position (Duns Scotus, many Franciscans): the Incarnation was absolutely predestined for the glorification of Christ independently of the Fall. Neither position is de fide; Pohle assesses both arguments and their theological weight.

Two articles establish the reality of vicarious atonement. Article 1: defines vicarious atonement (satisfactio vicaria) — satisfaction offered by one person in the name of and in place of another, accepted by the offended party as equivalent to personal satisfaction; distinguishes it from mere exemption, imputation (Protestant), or exemplarism (Abelard, Modernists). Article 2: proves the dogma from Scripture (Isaiah 53; Rom. 5; Gal. 3; Heb. 9–10) and Tradition — de fide from Trent.

Two articles on the properties of the atonement. Article 1: Intrinsic Perfection (Adequacy) — the satisfaction of Christ was not merely sufficient but strictly adequate (de condigno) and even superabundant, because the subject (the divine Person of the Logos) endows every human act of Christ with infinite dignity and worth; refutes Scotist diminution; treats Anselm's position and Aquinas's refinement. Article 2: Extrinsic Perfection (Universality) — Christ died for all men without exception, including those who are damned; refutes strict Calvinist predestinarianism; treats the distinction between sufficient and efficacious redemption.

Three articles on the acts by which the atonement was concretely realized. Article 1: Christ's Death on the Cross — the death of the God-man is the culminating soteriological act; de fide; Christ died for all. Article 2: Christ's Descent into Hell — de fide (Apostles' Creed); the limbus patrum (not hell of the damned); its soteriological significance (liberation of the just, Christ's triumph). Article 3: The Resurrection — de fide; the third-day resurrection is an essential part of the Redemption (not merely its confirmation); its apologetic and soteriological significance.

Chapter I opens the treatise on Christ's priestly office. §1 demonstrates that Christ's death was a true sacrifice in the strict theological sense — not merely a figure or a moral example. Defines sacrifice (external offering of a sensible thing, made to God alone, by a legitimately appointed minister, involving the destruction or immolation of the thing offered, as an acknowledgment of God's supreme dominion). Proves each element from Scripture (Hebrews passim; Eph. 5:2) and Tradition — de fide from Trent.

§2 proves that Christ is a true priest in the strict sense — not merely metaphorically. Defines priesthood (official power to offer sacrifice to God on behalf of men). Proves Christ's priesthood from Hebrews (the entire epistle is an extended proof), the Psalms (Ps. 109:4 — 'a priest forever according to the order of Melchisedech'), and Tradition — de fide. Treats Christ's priesthood as unique: He is simultaneously offerer and victim; His priesthood is eternal; it is the basis of the Mass as a true sacrifice.

Defines prophecy and its three modes (ecstasy, vision, instinct). Proves Christ's prophetical office: He is the Prophet promised by Moses (Deut. 18:15 — de fide); He exercised prophecy actively throughout His ministry (the Passion, the fall of Jerusalem, the spread of the Church, the last things). Christ's prophetical office is exercised even now through Scripture, Tradition, and the magisterium of the Church.

Defines kingship and distinguishes Christ's twofold kingdom: the kingdom of grace (the Church militant, over all men by title, over the faithful by actual subjection) and the kingdom of glory (the beatific vision). Proves Christ's universal kingship from Scripture and Tradition — de fide. Treats the temporal power of the Church (indirect power in temporal matters), the rights of Christ as King over civil society, and the social kingship of Christ (Quas Primas, Pius XI).

Treats the apparent difficulty: if God is absolutely immutable, how could the atonement reconcile Him to man? Resolution: it was not God who changed but man; the atonement objectively removed the obstacle (sin) that stood between man and God; God's acceptance of the satisfaction is an immanent eternal act, not a new temporal decision. Draws on Aquinas's treatment in S. Theol. IIIa, qu. 49.
