AN OPEN APPEAL TO THE CARDINALS OF THE CATHOLIC CHURCH
To their Most Reverend Eminences, the Cardinals of the Holy Roman Church,
Since it is a truth contained in the Word of God, and taught by the ordinary and universal magisterium of the Catholic Church, that criminals may lawfully be put to death by the civil power when this is necessary to preserve just order in civil society, and since the present Roman pontiff has now more than once publicly manifested his refusal to teach this doctrine, and has rather brought great confusion upon the Church by seeming to contradict it, and by inserting into the Catechism of the Catholic Church a paragraph which will cause and is already causing many people, both believers and non-believers, to suppose that the Church considers, contrary to the Word of God, that capital punishment is intrinsically evil, we call upon Your Eminences to advise His Holiness that it is his duty to put an end to this scandal, to withdraw this paragraph from the Catechism, and to teach the word of God unadulterated; and we state our conviction that this is a duty seriously binding upon yourselves, before God and before the Church.
