According to the Catechism’s section on original sin:
404 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.
This sounds to me as though the Catholic Church is teaching that not only is human nature corrupted because of Adam, but that all humans are born guilty of Adam’s sin because Adam’s guilt is imputed to all people.
Is that right? Are there any other sources that make this clear?
