Ok. I’ll paste this again. It’s from the catechism, the constitution of the church, and, no , we are not living in post catechism times. Humans can stray from the rules leading others to do so but it is not right when it happens. The American bishops say what up assert they are saying, yes. But the church says the following:
2265 Legitimate defense can be not only a right but a grave duty for one who is responsible for the lives of others. The defense of the common good requires that an unjust aggressor be rendered unable to cause harm. For this reason, those who legitimately hold authority also have the right to use arms to repel aggressors against the civil community entrusted to their responsibility.”
And the Church would not impose itself onto our constitution to assert whom they choose should be authority. That the 2nd amendment states that individuals have that authority is unquestioned
And that entry in the Catechism has its roots in Romans:
Paraphrased:
“It is good to fear the sword of the state, for it has its purpose.”
