Capital Punishment
Political Responsibility
p. 16.
"The Church’s commitment to the value and dignity of human life leads us to oppose the use of the death penalty. We believe that a return to the use of the death penalty is further eroding respect for life in our society. We do not question society’s right to protect itself, but we believe that there are better approaches to protecting our people from violent crimes. The application of the death penalty has been discriminatory toward the poor, the indigent, and racial minorities. Our society should reject the death penalty and seek methods of dealing with violent crime that are more consistent with the gospel visions of respect for life and Christ’s message of healing love. This principle is set forth in the new Catechism of the Catholic Church
USCCB
Catechism of the Catholic Church
2266
“Preserving the common good of society requires rendering the aggressor unable to inflict harm. For this reason the traditional teaching of the Church has acknowledged as well-founded the right and duty of legitimate public authority to punish malefactors by means of penalties commensurate with the gravity of the crime, not excluding, in cases of extreme gravity, the death penalty. For analogous reasons those holding authority have the right to repel by armed force aggressors against the community in their charge.”
2267
“If bloodless means are sufficient to defend human lives against an aggressor and to protect public order and the safety of persons, public authority should limit itself to such means, because they better correspond to the concrete conditions of the common good and are more in conformity to the dignity of the human person.”
Catechism
Although not overtly condemning capital punishment, the
Catechism does strongly discourage it.
I believe this means necessary use of force to save an innocent life. For instance, a perpetrator has hostages and is proven to be willing to take life, law enforcement officials may use necessary force to save the innocent.
Once a perpetrator has been incorporated in to the penal system chances are lives are safe and there is a possiblity of conversion by the perpetrator.
Capital punishment should not be a tool of revenge. Vengeance is not ours.
