Catholic Church and capital punishment
Since 2018, the Catechism of the Catholic Church has stated that the Catholic Church opposes the death penalty. That year, Pope Francis revised the Catechism to read that the death penalty is "inadmissible" and that the Church works "for its abolition worldwide." Prior to this, the 1992 Catechism promulgated by Pope John Paul II had permitted the practice, reading that "the traditional teaching of the Church does not exclude recourse to the death penalty", though he stated that the practice must be limited only to extreme circumstances.
