The Catholic claim
Orthodox writers frequently prefer “ancestral sin”: Adam’s sin brings death, corruption, and a wounded human condition, without saying infants inherit Adam’s personal guilt. Catholic dogma teaches that original sin is transmitted by propagation, not imitation, and that it is the deprivation of original holiness and justice—not that babies committed Adam’s act (CCC 404–405).
Much heat is semantic. Both East and West baptize infants, confess Christ’s victory over death, and deny Pelagian denial of inherited wound. The remaining edge is how strongly one speaks of guilt, justice, and the effects Baptism remits.
Biblical evidence
“Sin came into the world through one man, and death through sin” (Rom 5:12). “By one man’s disobedience the many were made sinners” (Rom 5:19). Paul binds Adam and Christ as corporate heads—condemnation and justification are not merely bad examples and good examples.
Psalm 51 and Job’s frailty language feed both traditions’ sense that we are born into a broken solidarity. Infant baptism in the early Church assumes infants need the new birth—not that they are personally wicked like adult criminals.
- Romans 5:12-19
“Therefore as sin entered into the world through one man, and death through sin; and so death passed to all men, because all sinned.”
- 1 Corinthians 15:21-22
“For since death came by man, the resurrection of the dead also came by man. For as in Adam all die, so also in Christ all will be made alive.”
- Ephesians 2:1-5
“You were made alive when you were dead in transgressions and sins, in which you once walked according to the course of this world,”
- Psalm 51:5
“Behold, I was born in iniquity. In sin my mother conceived me.”
- John 3:5-6
Catholics deny that infants are guilty of Adam’s personal choice as if they chose it. They affirm a real lack of sanctifying grace and a wounded nature that Baptism heals—stronger than “mere mortality,” weaker than “infants are damned for their own sins.”
Tradition and magisterium
The Catechism: original sin is called “sin” analogically—it is contracted, not committed; a state, not an act (CCC 404). It is transmitted by propagation; Baptism erases original sin but leaves concupiscence to be wrestled (CCC 405).
Council of Trent rejected Pelagian denial of original sin’s transmission. Eastern emphasis on death and corruption is not heresy; denying any inherited deprivation that Baptism addresses would be.
History and development
Augustine’s anti-Pelagian fight shaped Western vocabulary of guilt and mass damnata—sometimes over-read by later critics. Greek Fathers stress mortality, the devil’s tyranny, and therapeutic salvation. Modern Orthodox–Catholic dialogue often finds overlapping substance beneath different accents.
“But this present life… is a scene of contest… and therefore he who was conquered and expelled from paradise was also conquered and expelled from life… so that… man… might be disciplined… and afterwards be resurrected…”
Early emphasis on Adam’s fall, death, and pedagogy—shared East–West soil before later vocabulary fights.
“The guilt of this concupiscence… is born with infants… and it is this that is remitted for them when they are baptized…”
Western clarity that Baptism remits a guilt contracted by birth—not that infants personally sinned like adults.
“How then did death enter in and prevail? Through the sin of one man… What then? Tell me, was it for the sin of that one man that Adam was condemned?… We were all under sin and death…”
Eastern preacher affirming solidarity in Adam’s death and sin—without later scholastic terms.
Mastery and practice
Explain Catholic original sin so an Orthodox hearer does not hear “God hates babies,” and so a Protestant hearer does not hear “Baptism is optional.”
- Use Romans 5 with CCC 404’s analogical “sin”
- Affirm infant baptism’s rationale in both traditions
- Separate Augustinian rhetoric from defined dogma
Common objections
Original sin is a Latin invention alien to the East.
The East baptizes infants and reads Romans 5. Vocabulary differs; denial of any inherited Adamic wound is not classical Orthodoxy. Catholic dogma specifies deprivation of holiness and justice—compatible with strong Eastern stress on death and corruption.
Catholics say babies go to hell for Adam’s sin.
The Church has never defined that unbaptized infants are damned to the hell of the damned. She affirms the necessity of Baptism and entrusts unbaptized infants to God’s mercy (CCC 1261). Original sin’s gravity is not a mandate to despair of children.
Ancestral sin is only mortality; skip guilt language.
If Adam only made us mortal, Baptism’s remission language and Romans 5’s “made sinners” are under-explained. Catholics keep guilt/justice language carefully: contracted state, not personal adult crime.
