There is no " ex cathedra" dogma of the Catholic church that the death penalty is wrong.
Liberal Catholic heirarchy like present group are entitled to their personal opinions on policy.
If the present Pope doesn't like the death penalty that's his opinion. Until it is made a dogma by an official pronouncement a Catholic can tell him to go take a hike.
But if this anti American Pope makes it official "ex cathedra" a matter of faith and morals taught to the whole church,then if you are still in favor of the death penalty you should be thrown out of the Church.
Not likely to happen since the Catholic church has gone along with the death penalty for centuries suported it and I believe at times had some heretics executed. -Tom
When the pope was monarch of the larger Papal States until the 1850s, the popes regularly carried out the death penalty for the same sorts of civil crimes as most governments. John Paul II is simply not personally favorable to the death penalty. It is NOT a matter of dogma any more than is Vatican foreign policy.
By the standards you seem to apply, most churches would be "anti-American." I personally believe that the war in Iraq was just and moral. No Catholic is required to believe otherwise.
