Forgive perhaps, but offer mercy, not so much.
I think you may be forgetting the commandments from Jesus, to love God with all we have, and to love our neighbor as ourselves. We are called to
always use mercy as our guide. For example, it is merciful to protect people from a murderer, so we incarcerate the aggressors. However, the treatment of the murderer, everything we do for him, is done with mercy in mind. If punishment itself is not merciful, (enhancing conversion) then its application is unwarranted.
Forgiveness has been called the most important act of mercy. Forgiveness is for the person who forgives, it changes the sense of debt, the sense of trespass, that colors the way we see those who have wronged us. Forgiveness is a call to holiness.
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. (Catechism of the Catholic Church, ed 1, 1992)
That edition is no longer valid as catechesis, Ender, without including CCC 2267.
“Tradition is a living reality and only a partial vision can think of ‘the deposit of faith’ as something static. The Word of God cannot be conserved in mothballs as if it were an old blanket to be preserved from parasites. No. The Word of God is a dynamic reality, always alive, that progresses and grows because it tends towards a fulfillment that men cannot stop.”
Pope Francis
One has to ask the writer(s) of the first edition, “have you forgiven murderers?”. Every Catholic should ask of every person commenting on the death penalty the same question.
A Catholic who holds something against a person who refuses to forgive is called to forgive such person.
Catholics should listen to people who forgive as the truthful guides. We trust the hierarchy to select leaders who follow Jesus’ commandments to love and forgive. When the dissenting voice comes from a place of non-forgiveness, we are not following Christ in abiding the dissenting voice.
Ender, if there were a bishop today voicing your opinion, he would be all over the news as a dissenting voice. Catholics would be wise to call to question his commitment to mercy and forgiveness.
