That means you know you are bound to believe Satan exists and plenty of proof has been shown to you on the Church teaching.
You are also bound to believe Adam and Eve were real people and not symbolic. The Church is clear and unambiguous on this.
CCC 416 By his sin
Adam, as
the first man, lost the original holiness and justice he had received from God, not only for himself but for all human beings.
CCC 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”.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. 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.
CCC 359 “In reality it is only in the mystery of the Word made flesh that the mystery of man truly becomes clear.”
St. Paul tells us that the human race takes its origin from two men: Adam and Christ. . .
The first man, Adam, he says,** became a living soul**, the last Adam a life-giving spirit. The first Adam was made by the last Adam, from whom he also received his soul, to give him life… The second Adam stamped his image on the first Adam when he created him. That is why he took on himself the role and the name of the first Adam, in order that he might not lose what he had made in his own image. The first Adam, the last Adam: the first had a beginning, the last knows no end. The last Adam is indeed the first; as he himself says: “I am the first and the last.”
HUMANI GENERIS
(Concerning Some False Opinions Threatening to Undermine the Foundations of Catholic Doctrine)
Pope Pius XII
- 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.
Regarding the link to the paper by the Commission I have read that before but went through it again. there is nothing in that paper which states or even suggests Adam was not a real person.
