That’s an extremely novel interpretation, historically speaking.
I’m not speaking historically. I’m citing
Catechism 2267: ‘Assuming that the guilty party’s identity and responsibility have been fully determined, the traditional teaching of the Church does not exclude recourse to the death penalty, if this is the only possible way of effectively defending human lives against the unjust aggressor. If, however, non-lethal means are sufficient to defend and protect people’s safety from the aggressor, authority will limit itself to such means, as these are more in keeping with the concrete conditions of the common good and more in conformity to the dignity of the human person. Today, in fact, as a consequence of the possibilities which the state has for effectively preventing crime, by rendering one who has committed an offense incapable of doing harm - without definitely taking away from him the possibility of redeeming himself - the cases in which the execution of the offender is an absolute necessity “are very rare, if not practically nonexistent.” [John Paul II,
Evangelium Vitae 56]’
The Church’s teaching is talking about today, not historically. I know that there are Catholics who continue to argue that the Church is not against the death penalty, but it is very difficult to see how one can arrive at that conclusion based on the available documents. Also, I do not know of any national or regional conference of Catholic bishops that does not oppose the death penalty. The Catholic bishops of the Philippines themselves are strongly opposed to the death penalty.
Having the US Supreme Court against you is an indicator of being right.
Well, the US Supreme Court is tasked with interpreting the law of the United States. If you dislike some of the court’s judgements (I assume e.g. Roe v. Wade) that is surely more a problem with US law, not the court per se. Anyway, I was just citing the court’s judgements as one example. Like I say, most death penalty retentionist states impose the death penalty only for murder. In my own country, the UK, the death penalty was restricted in 1861 to five offences: murder, plus treason (ceased to be capital offence 1998), espionage (ceased to be capital offence 1981), arson in various premises connected with the Royal Navy (ceased to be capital offence 1971), and piracy with violence (ceased to be capital offence 1998). We also retained the death penalty for various military offences such as assisting the enemy or mutiny (death penalty abolished for all offences 1998). You can’t really put drug dealers in the same category as people who commit other non-murder offences such as treason or assisting the enemy.
