To what degree of certainty is the Catholic Church condemnation of abortion infallible?

Yes, informed Catholics know that the abortion is condemned by the Catholic Church. What is not known by most Catholics is two enhancements to the condemnation.

1. EV made the condemnation of abortion an infallible dogma where as previously it was a definitive teaching.
2. EV elevated the condemnation of abortion to the same category as the founding of the Catholic Church by Christ, The Real Presence in the Eucharist and all the Marion dogmas and more. It is a dogma of Divine and Catholic Faith and doubters and deniers are considered heretics from the Catholic Faith.

This happened 23 years ago but I have never heard a Cardinal, Bishop, apologist or theologian mention its grave seriousness equal to the highest dogmas. Never. I had never known this until this week and I would imagine very few Catholics have ever heard this. I have talked to many Catholics who did not know it was an infallible dogma much less a dogma equal to the founding of the Church by Christ. This is actually a staggering denunciation of abortion and all Catholics should be aware it instead of complete silence about its exalted category.

Why would the current Pope and Bishops not tell all Catholics how important this dogma is?

The Catholic Church's condemnation of abortion falls under dogmas of faith and morals (de fide et moribus).

Pope Pius XI's condemnation of contraception in the encyclical on Christian marriage, Casti Connubii, has been considered an ex cathedra (infallible) statement. What Cartechini says regarding contraception can be applied mutatis mutandis to abortion:

even if it is not a dogma of the faith, the doctrine he promulgated certainly is infallibly true because the Pope authoritatively and with solemn words expresses a moral doctrine that from ancient times the ordinary and universal magisterium has constantly proposed must be be held and observed.

As Evangelium Vitæ §62 says, "the moral condemnation of abortion" "is based upon the natural law and upon the written Word of God, is transmitted by the Church's Tradition, and taught by the ordinary and universal Magisterium."

I went back and reviewed my previous posts and realized that critical parts were edited out or I missed them in my original post. Here are the two critical points that were missing in my original post:

1. Extract from EV #62: “Given such unanimity in the doctrinal and disciplinary tradition of the Church, Paul VI was able to declare that this tradition is unchanged and unchangeable. 72 Therefore, by the authority which Christ conferred upon Peter and his Successors, in communion with the Bishops-who on various occasions have condemned abortion and who in the aforementioned consultation, albeit dispersed throughout the world, have shown unanimous agreement concerning this doctrine-I declare that direct abortion, that is, abortion willed as an end or as a means, always constitutes a grave moral disorder, since it is the deliberate killing of an innocent human being. This doctrine is based upon the natural law and upon the written Word of God, is transmitted by the Church's Tradition and taught by the ordinary and universal Magisterium.”

The importance here is that in the prior paragraph the Pope reference 3 prior Popes and Vatican II. In this paragraph the Pope speaks with the authority of St. Peter and the world-wide bishops, Church tradition, natural law, the written word of God and taught by the ordinary and universal magisterium and DECLARES his condemnation of abortion with the authority of St. Peter. I wanted to clear this up so there would be no confusion that EV is not just a teaching, it is an infallible doctrine.

2. Doctrinal Commentary on the Concluding Formula of the Professio fidei:

paragraph 11. To the truths of the first paragraph belong the articles of faith of the Creed, the various christological dogmas21 and marian dogmas;22the doctrine of the institution of the sacraments by Christ and their efficacy with regard to grace;23the doctrine of the real and substantial presence of Christ in the Eucharist24and the sacrificial nature of the eucharistic celebration;25the foundation of the Church by the will of Christ;26the doctrine on the primacy and infallibility of the Roman Pontiff;27 the doctrine on the existence of original sin;28the doctrine on the immortality of the spiritual soul and on the immediate recompense after death;29the absence of error in the inspired sacred texts;30 **the doctrine on the grave immorality of direct and voluntary killing of an innocent human being.**31

This is the CONGREGATION FOR THE DOCTRINE OF THE FAITH expounding on the truths that are of Divine and Catholic Faith signed by Joseph Card. Ratzinger Prefect.

The last entry in #11 clearly puts the condemnation of abortion in the same Divine and Catholic Faith category as the founding of the Catholic Church by Christ, all the Marian doctrine and the Real Presence of Christ in the Eucharist.

This is really an astounding, staggering Catholic dogmatic statement on abortion that almost no Catholics, hierarchy, Bishops, theologians, apologists and laity are aware of. I am trying to change that, ergo the purpose of the topic- to save the unborn by telling the true seriousness of the condemnation of abortion.
