Yes, it is. One would think that if Pius IX meant that the invincibly ignorant would not remain invincibly ignorant, that he would have said that. He was anything but ambiguous. And, considering the immense significance of someone being invincibly ignorant, it seems to reason that His Holiness of blessed memory would have clearly stated this significant change in the person from being invincibly ignorant to being miraculously not ignorant, and baptized with water by an angel, or some other extraordinary means.
Instead, he acknowledges the existence of the invincibly ignorant (at least in 1863) and states that God will not punish them if they do not deliberately sing, observe the natural law and are ready to obey God.
Re: the article posted, written by Fr. Mueller. The objections in the article are not fit for this discussion, because I (nor do I think is anyone else) am not arguing that invincible ignorance is a means to salvation. That is God's grace and mercy, not a merit (or demerit) of man.
The principle of BOD/BOB/Invincible ignorance is not that man's salvation is an effect caused by his own action or state (in desiring baptism, dying for the faith before it, or being invincibly ignorant of it) but that his salvation comes about no differently than anyone else's: by the grace of God.
This is from the Dimond boys; although i disagree with them on many things, as far as i can tell they are right regarding this:
First, notice that Pope Pius IX specifically condemns the idea that a man “living in
error and separated from the true Faith” can be saved. What, may I ask, is the idea of
salvation for the “invincibly ignorant”? Why, of course, it is the idea that a man living in
error and separated from the true Faith can be saved. So, the very concept of salvation
for the “invincibly ignorant” is condemned as QUITE CONTRARY TO CATHOLIC
TEACHING in this very docuмent of Pope Pius IX.
Second, notice again that Pope Pius IX does not say anywhere that the invincibly
ignorant can be saved where they are. Rather, he is reiterating that the ignorant, if they cooperate with God’s grace, keep the natural law and respond to God’s call, they can by
God’s “operating power of divine light and grace” [being enlightened by the truth of the Gospel]
attain eternal life, since God will certainly bring all of his elect to the knowledge of the
truth and into the Church by baptism. According to the specific definition of Sacred
Scripture, “divine light” is the Gospel truth of Jesus Christ (the Catholic Faith) which
removes the ignorant from darkness.
Ephesians 5:8 “For you were heretofore darkness, but now light in the Lord.
Walk then as children of the light.”
1 Thess. 5:4‐5 “But you, brethren [believers], are not in darkness… For all you
are the children of the light.”
Colossians 1:12‐13: “Giving thanks to God the Father, who hath made us worthy
to be partakers of the lot of the saints in light: Who hath delivered us from the
power of darkness, and hath translated us into the kingdom of the Son of His
love.”
1 Peter 2:9: “But you are a chosen generation… a purchased people: that you may
declare his virtues, who hath called you out of darkness into His marvelous
light.”
2 Corinthians 4:3‐4: “And if our gospel be hid, it is hid to them that are lost, In
whom the god of this world [Satan] hath blinded the minds of unbelievers, that
the light of the gospel of the glory of Christ, who is the image of God, should
not shine unto them.”
2 Timothy 1:10: “But is now made manifest by the illumination of our Savior
Jesus Christ, who hath destroyed death, and hath brought to light life and
incorruption by the Gospel.”
Pope Pius IX, Vatican I (+1870): “… no one can ‘assent to the preaching of the
Gospel,’ as he must to attain salvation, without the illumination and
inspiration of the Holy Spirit, who gives to all a sweetness in consenting to and
believing the truth.”
So, we must not interpret Pius IX’s words in Quanto Conficiamur Moerore about the
good‐willed ignorant being saved by receiving “divine light and grace” contrary to their
clear scriptural and Traditional meaning, which is that divine light and grace is received
by hearing of the Gospel, believing it and being baptized. Thus, in Quanto Conficiamur
Moerore, Pius IX is saying that the good‐willed, sincere person who is ignorant of the
Faith will be “illuminated” by receiving the “divine light” (hearing the Gospel) and will
enter the Catholic Church so that he can be saved.
