PASCENDI DOMINICI GREGIS

37. But it is not solely by objective arguments that the non-believer may be disposed to faith. There are also those that are subjective, and for this purpose the modernist apologists return to the doctrine of immanence. They endeavor, in fact, to persuade their non-believer that down in the very depths of his nature and his life lie hidden the need and the desire for some religion, and this not a religion of any kind, but the specific religion known as Catholicism, which, they say, is absolutely postulated by the perfect development of life. And here again We have grave reason to complain that there are Catholics who, while rejecting immanence as a doctrine, employ it as a method of apologetics, and who do this so imprudently that they seem to admit, not merely a capacity and a suitability for the supernatural, such as has at all times been emphasized, within due limits, by Catholic apologists, but that there is in human nature a true and rigorous need for the supernatural order. Truth to tell, it is only the moderate Modernists who make this appeal to an exigency for the Catholic religion. As for the others, who might he called integralists, they would show to the non-believer, as hidden in his being, the very germ which Christ Himself had in His consciousness, and which He transmitted to mankind. Such, Venerable Brethren, is a summary description of the apologetic method of the Modernists, in perfect harmony with their doctrines -- methods and doctrines replete with errors, made not for edification but for destruction, not for the making of Catholics but for the seduction of those who are Catholics into heresy; and tending to the utter subversion of all religion.

Seems pretty clear His Holiness Pope St. Pius X condemned invincible ignorance and implicit desire for baptism for those that sadly die outside the ark of salvation
