Suprema Haec Sacra
A year before the appearance of the Humani generic, the Supreme Sacred Congregation of the Holy Office sent to the Most Reverend Archbishop of Boston a letter containing explanations on the subject of the dogma that no one can be saved outside of the Catholic Church. This highly important document was approved by Pope Pius XII. Despite the fact that it was sent prior to the issuance of the Humani generic, it was not published until two years after the publication of the encyclical. This Holy Office letter is the Suprema, haec sacra, one of the most important doctrinal statements which appeared during the reign of the late and beloved Sovereign Pontiff.15
This document set forth clearly and in detail, and as the authentic teaching of the Holy See, the explanation of the dogma on the necessity of the Catholic Church for the attainment of eternal salvation which had long been presented as common teaching in the theological teaching on the Church itself. The elements of the exposition contained in the Suprema, haec sacra had, of course, long since been presented to the faithful in previous authoritative statements of the Church’s magisterium. The entire doctrine, however, had never before been synthesized and set forth as clearly and in such scientifically complete detail in any previous document.
The Suprema haec sacra insisted again upon the fact that the declaration: “there is no salvation outside the Church” is an infallible statement which the Church has always preached and will never cease to preach, and it qualified this statement as a dogma. It explained that the Church understood this dogma to mean that the Church is necessary for the attainment of eternal salvation with both the necessity of precept and the necessity of means. Furthermore, it taught that the Church was a means of salvation to be classified among those quae divina sola institutione, non vero intrinseca necessitate, ad finem ultimum ordinantur, and that thus, under certain circumstances, salvation can be attained when the Church itself is used or entered voto solummodo vel desiderio. Again it brought out the Catholic teaching that, in cases where men are invincibly ignorant of the true Church, "God accepts also an implicit desire (votum), so called because it is included in that good disposition of soul whereby a person wishes his will to be conformed to the will of God."16
The strictly doctrinal portion of the Suprema haec sacra ends with this essential teaching:
But it must not be thought that any kind of desire of entering the Church suffices that one may be saved. It is necessary that the desire by which one is related to the Church be animated by perfect charity. Nor can an implicit desire produce its effect, unless a person has supernatural faith: “For he who comes to God must believe that God exists and is a rewarder of those who seek Him” (Hebrews, 11:6). The Council of Trent declares [Session VI, chap. 8] “Faith is the beginning of man’s salvation, the foundation and root of all justification, without which it is impossible to please God and attain to the fellowship of His children” (Denzinger, n. 801).17"
