Fratelli Tutti §263
Fratelli Tutti: On Fraternity and Social Friendship
263 There is yet another way to eliminate others, one aimed not at countries but at individuals. It is the death penalty. Saint John Paul II stated clearly and firmly that the death penalty is inadequate from a moral standpoint and no longer necessary from that of penal justice. There can be no stepping back from this position. Today we state clearly that “the death penalty is inadmissible” and the Church is firmly committed to calling for its abolition worldwide.
