I quoted Pope Pius XII, who reigned for 19 years just prior to Vatican II. I suggest you compare his comment on the Church and salvation (I quoted it earlier in Post 60) to those of any of his successors.
What, this one? Looking at the letter from the Holy Office (
here), the introductory letter from Archbishop Cushing clearly states, "
The Supreme Pontiff, His Holiness, Pope Pius XII, has given full approval to this decision".
Letter of the Holy Office to Archbishop Cushing of Boston (Directly approved by Pope Pius XII, August 8, 1949): Canon Law Digest, Vol III, 1953, pg 525, Canon 1324 (Dangers to the Faith) (Excerpts):
"In His infinite mercy God has willed that the effects, necessary for one to be saved, of those helps to salvation which are directed toward man's final end, not by intrinsic necessity, but only by divine institution, can also be obtained in certain circumstances when those helps are used only in desire and longing. This we see clearly stated in the Sacred Council of Trent, both in reference to the sacrament of regeneration and in reference to the sacrament of penance (<Denzinger>, nn. 797, 807). The same in its own degree must be asserted of the Church, in as far as she is the general help to salvation. Therefore, that one may obtain eternal salvation, it is not always required that he be incorporated into the Church actually as a member, but it is necessary that at least he be united to her by desire and longing.
However, this desire need not always be explicit, as it is in catechumens; but when a person is involved in invincible ignorance God accepts also an implicit desire, 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. These things are clearly taught in that dogmatic letter which was issued by the Sovereign Pontiff, Pope Pius XII, on June 29, 1943, <On the Mystical Body of Jesus Christ> (AAS, Vol. 35, an. 1943, p. 193 ff.). For in this letter the Sovereign Pontiff clearly distinguishes between those who are actually incorporated into the Church as members, and those who are united to the Church only by desire.
Pope Pius XII (Oct. 29, 1951): Address to the Congress of the Italian Catholic Association of Midwives:
"the state of grace at the moment of death is absolutely necessary for salvation. Without it, it is not possible to attain supernatural happiness, the beatific vision of God. An act of love can suffice for an adult to obtain sanctifying grace and supply for the absence of Baptism..."
An act of love, he said, is sufficient to obtain the salvific grace necessary for heaven - even if a person isn't a member of the church through baptism, as in the case of Jews, Buddhists, atheists and so on.
