Capital Punishment and the Catholic Church

The question of the death penalty has long been a topic of theological, moral, and social debate within the Catholic Church. Traditionally, the Church recognized the state’s right to impose capital punishment in extreme cases. However, the 2018 revision of the Catechism of the Catholic Church (CCC 2267) now declares the death penalty “inadmissible” in light of human dignity and modern penal systems.

Does this represent a change in doctrine? Can a future pope allow capital punishment again in extreme cases? And does the Fifth Commandment—“Thou shall not kill”—prohibit all forms of killing, including executions? These are serious questions that require an in-depth look at both Sacred Scripture and Sacred Tradition.

The previous version of CCC 2267 (1997) acknowledged that the death penalty could be permissible if it were the only way to protect human life from an unjust aggressor. However, it emphasized that, given modern penal systems, cases where execution was necessary were “very rare, if not practically nonexistent” (Evangelium Vitae, 1995).

The 2018 revision, issued under Pope Francis, took a firmer stance:

“The Church teaches, in the light of the Gospel, that ‘the death penalty is inadmissible because it is an attack on the inviolability and dignity of the person,’ and she works with determination for its abolition worldwide.” (CCC 2267, 2018 revision)

This shift raises several theological questions. If the death penalty was previously permissible, how can it now be inadmissible? Can future popes reverse this teaching if society changes?

The revised CCC 2267 comes from the ordinary magisterium, meaning Catholics are expected to give it religious submission of intellect and will (Lumen Gentium 25). However, because it is not an infallible dogmatic declaration, some level of theological reflection is still possible.

Some theologians argue that the Church has not declared the death penalty intrinsically evil, only unnecessary today. This leaves open the possibility that a future pope could refine or nuance the teaching. However, the Church’s current position is clear: Catholics are called to support its abolition worldwide.

A key concern is whether declaring the death penalty inadmissible contradicts the Bible and previous magisterial teachings.

Sacred Scripture on the Death Penalty

Genesis 9:6 – “Whoever sheds the blood of man, by man shall his blood be shed.”

Romans 13:4 – “For he [the ruler] does not bear the sword in vain; he is the servant of God to execute wrath on the wrongdoer.”

Exodus 21:12–14 – Prescribes capital punishment for certain crimes under the Old Law.

These passages indicate that God permitted the death penalty in certain circumstances. However, the Church also recognizes progress in moral understanding under the New Covenant, where Jesus calls for mercy and forgiveness (cf. John 8:1–11).

Church Fathers and Theologians on Capital Punishment

St. Augustine (City of God, Book 1, Ch. 21) – Taught that the death penalty was not forbidden by the Fifth Commandment if carried out by legitimate authority.

St. Thomas Aquinas (Summa Theologica, II-II, q. 64, a. 2) – Defended the state’s right to execute criminals for the common good.

Pope Pius XII (1954) – Reaffirmed that the state has the right to impose the death penalty.

Thus, for most of history, the Church distinguished between murder (always evil) and legitimate execution (sometimes permissible). The question today is whether the new context of human dignity and modern justice systems make capital punishment morally unjustifiable.

The commandment “Thou shall not kill” (Exodus 20:13) has sometimes been cited as an argument against capital punishment. However, Catholic teaching has never understood this as an absolute prohibition against all killing.

The original Hebrew word (ratsach) refers specifically to murder, not every act of killing. This is why the Bible simultaneously prohibits murder while allowing for just punishment, war, and self-defense.

The Catechism explains that:

• Murder (the deliberate killing of the innocent) is intrinsically evil.

• The state may use force, including lethal force, to protect society when necessary.

Thus, the Fifth Commandment does not contradict past Catholic teaching on capital punishment, but rather calls for prudence in its application.

The big question is whether a future pope could modify the teaching of CCC 2267. The answer depends on whether the Church has declared capital punishment intrinsically evil or merely inadmissible in today’s context.

Three Theological Possibilities:

1. If the Church teaches that capital punishment is intrinsically evil, it could never be reinstated under any circumstances.

2. If the teaching is a prudential judgment, a future pope could allow it again in extreme cases, such as societal collapse.

3. If conditions change, such as a return to lawlessness where executions become the only way to protect society, the teaching may require further development.

For now, however, Pope Francis has made the Church’s position clear: Catholics are called to work for the abolition of the death penalty.

What Do Scholars Say?

Supporters of the 2018 Revision

Cardinal Ladaria (CDF Prefect, 2018) – Argued this is a legitimate development in Catholic doctrine.

Fr. Thomas Petri, OP – Defended the consistency of the new teaching with past magisterial guidance.

Cautious Supporters (Development, but Not Dogma)

Dr. Edward Feser – Argues that while the teaching can develop, the Church cannot declare capital punishment intrinsically evil without contradicting past teaching.

Cardinal Raymond Burke – Stresses that Catholics must respect the Pope’s teaching, but the death penalty remains morally possible in theory.

Critics and Traditionalists

Bishop Athanasius Schneider – Warns that declaring the death penalty always immoral undermines past magisterial consistency.

Dr. John Joy – Notes that the wording “inadmissible” is ambiguous and could lead to theological confusion.

---

The death penalty debate challenges Catholics to think deeply about justice, human dignity, and Church teaching. While the Church historically permitted capital punishment, modern developments have led the Magisterium to oppose it in practice.

Yet, theological discussions continue. Can this teaching be revised again? How does it interact with past magisterial statements? For now, Pope Francis calls Catholics to work toward abolition, trusting in God’s justice and mercy.
