(1) I regard the infusion of immortal souls as an incoherent idea. Humans evolved moral and spiritual consciousness over a long period of time.
An immortal soul is a soul that survives death and experiences an afterlife. If humans evolved a moral and spiritual consciousness, at what point in history did humans experience an afterlife after physical death?
If you find it helpful to accept the literal creation of “Adam” 6,000-10,000 years ago, then by all means do so.
I am not interested in what is helpful. I am interested in the truth – ie, what Scripture and Tradition teach.
(2) Since I regard “Adam” and “Eve” as theological symbols, I regard them symbolically as the parents of humankind.
If you regard Adam and Eve as theological symbols and not real people, you are engaging in private interpretation of Scripture.
The Fundamentals of Catholic Dogma by Dr Ludwig Ott (1974):
The whole human race stems from one single human pair [sententia certa]. This teaching pertains to the Faith. It is theologically certain. It is a doctrine on which the Teaching Authority of the Church has not yet finally pronounced, but whose truth is guaranteed by its intrinsic connection with the doctrine of Revelation.
Whilst not a dogma, the unity of the human race is a necessary pre-supposition of the dogma of Original Sin and Redemption.
According to the 1909 Biblical Commission, the literal historical sense is not to be doubted in regard to:
The first man was tested by God to prove his obedience
Through the Devil’s temptation the first man transgressed the divine command
From the Original Sin, our first parents, Adam and Eve, were deprived of their original condition of innocence.
Humani Generis, Pope Pius XII, 1950 –
All human beings now on Earth have Adam for their ancestor. Because of this descent from Adam, we are born with Original Sin.
Vatican II affirms that Adam and Eve were real people – not mere theological symbols:
Constitution on the Church, Vatican II, 1964, - sections 2 & 56;
Nostra aetate, Vatican II, 1965, - section 1.
On the Church in the Modern World, Vatican II, 1965, - sections 13, 18 & 22. **Adam, said Gaudium et Spes, was the 1st man, and man would have been immune from bodily death if sin had not entered the world through him. **
Credo of the People of God, Pope Paul VI, 1968.
In 1979 Pope John Paul II in Redemptor Hominis sections 1, 8 & 14.
The Catechism affirms that Adam and Eve were real people:
Paragraph 360 of the Catechism of the Catholic Church:
Because of its common origin the human race forms a unity for
“from one ancestor [God] made all nations to inhabit the whole earth”. [See also: CCC 28, 225, 360, 404, 412, 416, 417, 775, 831, 842, 1939]
Paragraph 375 of the Catechism of the Catholic Church:
The Church, interpreting the symbolism of biblical language in an authentic way, in the light of the New Testament and Tradition, teaches that **our first parents, Adam and Eve, were constituted in an original “state of holiness and justice.” **
Paragraph 390 of the Catechism of the Catholic Church:
The account of the fall in Genesis 3 uses figurative language, but affirms a primeval event, a deed that took place at the beginning of the history of man.
Revelation gives us the certainty of faith that the whole of human history is marked by the original fault freely committed by our first parents.
