Feser and Bessette cite a number of examples, including Ambrose (Letter 90, to StudiusLetter 90 / 25, to Studius), Chrysostom (Homilies on the Statues, 6Homilies on the Statues, 6), Augustine (City of God 1.21City of God 1.21), and Jerome (Commentary on Jeremiah, Book 4, on 22:3). Also significant is the writing of Pope Innocent I, who refused to condemn Christian civil authorities who carried out the penalty:
Some opposed the death penalty more intensely, like Tertullian, but even he, say Feser and Bessette, did not oppose it in principle, but rather only that Christians should not participate in it (De Idolatria 19De Idolatria 19). (Incidentally, in the same work, Tertullian also taught that Christians should not be school teachers).
The "Roman Catechism""Roman Catechism" of the Council of Trent addresses this issue in the context of Ten Commandments, and says:
In the 19th and 20th centuries, popes exercising civil authority did not oppose the practice. Giovanni Battista Bugatti was the official executioner for the Papal States from 1796 to 1865, and put hundreds to death. Regarding more recent times, Cardinal Avery Dulles writes:
The Vatican City State from 1929 until 1969 had a penal code that included the death penalty for anyone who might attempt to assassinate the pope ("Catholicism and Capital Punishment""Catholicism and Capital Punishment")
At least two encyclicals of this period support the legitimacy of the practice, Pastoralis OfficiiPastoralis Officii (1891) and Casti ConnubiiCasti Connubii (1930), and Pius XII in several addresses in the 1950s supports it, perhaps most famously saying:
In recent yearsthe latter half of the 20th century, movement against capital punishment became more pronounced around the world, and leading Catholics expressed their opposition as well. The United States Conference of Catholic Bishops called for abolition in 1974, for example, and respected Franciscan Gino Concetti wrote against the penalty in 1977.
More recently, two popes in particular – John Paul II and Francis I – have made statements regarding capital punishment that seem, to some, to indicate a shift in the Church's view on capital punishment. Feser and Bessette describe three positions in an ongoing debate in Catholicism: is it a reversal of traditional Catholic doctrine, a development of doctrine, or a prudential judgment of doctrine? The different sides of this debate disagree on the strength of tradition outlined above (can it be contradicted by a pope?), and on the interpretation of the teachings of popes John Paul II and Francis.
Several significant landmarks of this period occur during John Paul II's papacy – the publication of the Catechism of the Catholic Church in 1992, the encyclical Evangelium VitaeEvangelium Vitae in 1995, and the updated Catechism published in 1997.
During the papacy of Benedict XVI, the Compendium of the Catechism of the Catholic ChurchCompendium of the Catechism of the Catholic Church was issued (2005). It follows the 1997 catechism, and cites the "very rare, if not practically nonexistent" language of Evangelium Vitae, but again does not call the practice illegitimate. Also in 2005, the USCCB published A Culture of Life and the Penalty of DeathA Culture of Life and the Penalty of Death, reiterating its call for the abolition of capital punishment in the United States, and in 2009, a synod of African bishops supported universal abolition.
