[quote=Brown10985]It seems to me that Pius XII is leaving polygenism open even though he doesn’t see how it can be reconciled with original sin. My question is why couldn’t this original bottleneck be a large group of people representing a “single Adam” and their sin lead to a “fall” and through propagation (original sin being defined at Trent) original sin being handed down from this large group of people to all generations.
Is this in union with the magisterium?
No, I don’t see how it can be considered open to accept a group rather than descent from a literal single pair in Adam and Eve. Even in the current Catechism it is specifically taught that humanity is one in Adam, that Adam and Eve are our first parents and that it is through propgation from them specifically that we inherit original sin.
**360 Because of its common origin the human race forms a unity, for “from one ancestor [God] made all nations to inhabit the whole earth”:226 …
226 Acts 17:26; cf Tobit 8:6.
**[size=3]The Scripture quoted iN CCC 360 NAB version:
Act 17: 26 He made from one the whole human race to dwell on the entire surface of the earth …
then the cross reference to Tobit:
Tobit 8:6 You made Adam and gave him his wife Eve to be his help and support; and** from these two the human race descended**.
[/size]**[size=3]404[/size] **How did the sin of Adam become the sin of all his descendants? The whole human race is in Adam “as one body of one man”.293 By this “unity of the human race” all men are implicated in Adam’s sin, as all are implicated in Christ’s justice. Still, the transmission of original sin is a mystery that we cannot fully understand. But we do know by Revelation that Adam had received original holiness and justice not for himself alone, but for all human nature. By yielding to the tempter, Adam and Eve committed a personal sin, but this sin affected the human nature that they would then transmit in a fallen state.294 It is a sin which will be transmitted by propagation to all mankind, that is, by the transmission of a human nature deprived of original holiness and justice. And that is why original sin is called “sin” only in an analogical sense: it is a sin “contracted” and not “committed” - a state and not an act.
We are one in Adam, Adam and Eve committed a personal sin, original sin is transmitted by propagation from them. All that seems to preclude a group of ancestors. If a single group of people being the solution was not ruled out by him, then Pope Pius XII would have easily seen the potential solution in a single group of ancestors (whether a few or thousands). The problem is that the Pope was teaching strict monogenism, one man and one woman, as the Church seems to have taught from the beginning which does conflict with the view of science that we come from a group of ancestors not a single pair.
. The Baltimore Catechism (I have the No. 2 version) says this:
51. Who were the first man and woman?
The first man and woman were Adam and Eve, the first parents of the whole human race.
The current CCC seems to uphold this. The term first parents is used to describe Adam and Eve. It affirms that they are the parents of the whole human race. We are one in Adam, not a representative group of Adams.
