Revised Response.
But since you asked here are the references: If you have a copy of " The Catholic Catechism " by the Servant of God, Fr. John A Hardon, S.J., you will find it on pgs 92 & 94, 105,106. The first is from a speech by Pius XII, " An Address to the Pontifical Academy of Sciences ( Nov 30, 1941): you will find it in Denzinger # 2285; also in the encyclical Humani Generis; Denzinger, 2327
The second is from Vatican 1, Dogmatic Constitution on the Catholic Faith, # 4. Denzinger 1797
It is best to give the information as Hardon gave it, since otherwise the key points might be missed. The Pope identified three " elements ( that ) must be retained as certainly attested by the sacred author ( of Genesis ), without any possibility of an allegorical interpretation. " I did not find the quoted statement in the Address.
- The essential superiority of man in relation to other animals, by reason of his spiritual soul.
- The derivation in some way of the first woman from the first man.
- The impossibility the immediate father or progenitor of man could have been other than a human being, that is, the impossibility that the first man could gave been the son o fan animal, generated by the latter in the proper sense of the term…" Only from a man can another man descend, whom he can call father and progenitor.
( 1-3 represent a synopsis of paragraphs of the Address entitled : " God, Teacher of Man " and " Man’s Greatness. While not formally expressed in Defined Dogma, they are a part o f the Deposit of the Faith, universally held by the Bishops and the Popes as far back as we can go and have been constantly upheld by Magisterial Teaching. It is my opinion that they are thus Infallible Teaching. )
A. Polygenism condemned:
" 35. It remains for Us now to speak about those questions which, although they pertain to the positive sciences, are nevertheless more or less connected with the truths of the Christian faith. In fact, not a few insistently demand that the Catholic religion takes these sciences into account as much as possible. This certainly would be praiseworthy in the case of clearly proved facts; but caution must be used when there is rather question of hypotheses, having some sort of scientific foundation, in which the doctrine contained in Sacred Scripture or in Tradition is involved. If such conjectural opinions are directly or indirectly opposed to the doctrine revealed by God, then the demand that they be recognized can in no way be admitted.
- For these reasons the Teaching Authority of the Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter – for the Catholic faith obliges us to hold that souls are immediately created by God. However this must be done in such a way that the reasons for both opinions, that is, those favorable and those unfavorable to evolution, be weighed and judged with the necessary seriousness, moderation and measure, and provided that all are prepared to submit to the judgment of the Church, to whom Christ has given the mission of interpreting authentically the Sacred Scriptures and of defending the dogmas of faithful[11] Some however rashly transgress this liberty of discussion, when they act as if the origin of the human body from preexisting and living matter were already completely certain and proved by the facts which have been discovered up to now and by reasoning on those facts, and as if there were nothing in the sources of divine revelation which demands the greatest moderation and caution in this question.
- When, however, there is question of another conjectural opinion, namely polygenism, the children of the Church by no means enjoy such liberty. For the faithful cannot embrace that opinion which maintains either that after Adam there existed on this earth true men who did not take their origin through natural generation from him as from the first parent of all or that Adam represents a certain number of first parents. Now it is in no way apparent how such an opinion can be reconciled with that which the sources of revealed truth and the documents of the Teaching Authority of the Church propose with regard to original sin, which proceeds from a sin actually committed by an individual Adam and which through generation is passed on to all and is in everyone as his own.[12]
( Humani Generis) " ( It is clear from the entire context that this teaching is Infallible)
B. Human soul, is form of the body, rational, immortal, unique to each individual, infused. ( And if infused and not passed on, it is created by God. My deduction. The entire text should be read.)
" For the soul not only truly exists of itself and essentially as the form of the human body, as is said in the canon of our predecessor of happy memory, pope Clement V, promulgated in the general council of Vienne, but it is also immortal; and further, for the enormous number of bodies into which it is infused individually, it can and ought to be and is multiplied… " ( Lateran Council V )
Item " B " would be Defined Dogma, as is clear from the context.
C. The sould is created immediately by God. ( Infallible teaching from Humani Generis and from Scripture, Tradition and constant Magisterial Teaching such as Humani Generis.)
D. The soul has the faculties of intellect, free will, and memory.
( Infallible, based upon Tradition and constant Magisterial Teaching, speculatively by St. Thomas and the Scholastics.)
For all the above and more see pars 355-368 in the CCC.
