Salvation Theology

Before the cross can be understood, the problem it solved must be stated precisely. Adam's original sin produced spiritual death — the separation of the creature from the Creator, the loss of the human spirit, the imputation of sin to every descendant through the federal headship. The fallen creature stands before the integrity of God in a condition that requires two things simultaneously: the divine integrity must be satisfied, and the creature's sin must be removed. These are not the same requirement. God is not satisfied simply because the sin is removed — His righteousness demanded the penalty, His justice required the execution of it. And the creature is not restored simply because God is satisfied — the sin that condemned him must be addressed directly. The cross is the only transaction in history that addressed both simultaneously without compromise to either.

Propitiation is the satisfaction of the divine integrity by the substitutionary death of Christ. The Greek word is ἱλαστήριον — the mercy seat, the lid of the ark of the covenant where the blood was applied on the Day of Atonement and God was satisfied. Paul uses this word in Romans 3:25 deliberately — the reader steeped in the Septuagint hears the entire Levitical atonement system compressed into one word and then superseded by it. The blood that was applied to the mercy seat year after year, which could never permanently satisfy, has been replaced by the blood of the One of whom the mercy seat was always a type. God is propitiated — not appeased in the pagan sense of placating an arbitrary deity, but satisfied in the precise judicial sense that His righteousness demanded and His justice executed.

Expiation is the removal of sin from the believer — the clearing of the record, the cancellation of the debt, the blotting out of the transgression. Where propitiation faces God and answers what the divine integrity requires, expiation faces man and answers what the condemned creature needs. The sin that separated the creature from the Creator is removed — not mitigated, not covered over temporarily as the Levitical sacrifices covered it year by year, but removed. Cancelled. Nailed to the cross. The certificate of debt that stood against the creature is taken out of the way. Isaiah saw this coming seven centuries before the cross and named it with the precision of a man who had seen the mercy seat and understood what it was pointing toward.

The writer of Hebrews is making a sustained argument that the Levitical system has been superseded by the priesthood of Christ. Every element of the old system — the repeated sacrifices, the annual Day of Atonement, the Levitical priests who served generation after generation — was a type pointing toward the antitype. The antitype has come. The type is obsolete. And the most concentrated expression of this argument is the phrase the writer repeats three times in close succession: once for all. The Greek is ἐφάπαξ — once, for all time, with permanent effect, requiring no repetition. The propitiation was made once. The expiation was accomplished once. The veil was torn once. The high priest entered the true holy of holies once. No subsequent sacrifice supplements what was accomplished. No ongoing priestly mediation is required. The once-for-all finality of the cross is the most direct doctrinal challenge to any system that requires the repetition or re-presentation of the sacrifice.

The Latin did more harm to the Greek than the Greek will ever do to the man who reads it. Jerome's Vulgate was a remarkable achievement — but it was also a theological act. Three translation choices embedded in the Latin text shaped the doctrinal architecture of Western Christianity for a thousand years in ways the Greek text does not support. μετάνοια — the change of mind that Paul and Jesus used for repentance — became poenitentiam, the Latin word for penance, importing an entire penitential system into texts that described an interior volitional reorientation. πρεσβύτερος — elder — became presbyter, which the ecclesiastical tradition read as priest, importing the entire Levitical sacerdotal system into the Church Age through a vocabulary choice. And the sacramental economy that followed these choices built its entire structure on the premise that the propitiation is ongoing — that the mass re-presents the once-for-all sacrifice — which is the precise claim that Hebrews 10:10-14 was written to refute.

If the propitiation is complete — if God has been fully satisfied by the once-for-all sacrifice of His Son — then the veil between the creature and the Creator has been torn and the access it prevented has been restored. If the expiation is complete — if the sin that condemned the creature has been removed, the record cancelled, the debt nailed to the cross — then there is no remaining barrier between the justified believer and the throne of grace. No mediating human priesthood is required because the One mediator has accomplished everything that any priesthood existed to accomplish. And if there is no mediating human priesthood, then every Church Age believer approaches the throne directly — as a royal priest, holding the warrant that the cross provides, entering the holy of holies through the torn veil by the blood of Jesus.
