Today Attorney General William Barr has announced that the US Department of Justice will resume the federal death penalty. Right on cue the USCCB is pitching its hissy fit. A telling phrase in the Catholic News Agency piece is this: "Catechism of the Catholic Church paragraph 2267 on the death penalty was updated in 2018 with a statement from Pope Francis, calling the death penalty inadmissible because it is an attack on the inviolability and dignity of the person."
NEWS FLASH! No one, not even a pope, can change Church teaching. The pope is to safeguard the Deposit of Faith, not mutate it according to his whims and fancies. Other popes throughout the centuries have upheld the legitimacy of the death penalty. Pope John Paul II, in paragraph 56 of Evangelium Vitae, while making his personal disapproval known, also upheld the licity of the death penalty.
Any statement that claims that the death penalty is inherently evil is rank heresy. It doesn't matter who utters it.
