Blessed Mother

Eve’s soul, which had been pure before the autumn , now lost the Holy Ghost , and she or he suffered all the emotions of a Fallen nature, especially confusion and loneliness. She rushed to Adam to form him share in her condition by persuading him of the goodness of the fruit. 

Adam could see that if he didn't do what Eve asked him, he would lose her. So, loving Eve quite God, he broke God’s commandment.

As St. Paul says, Adam wasn't deceived, whereas Eve was deceived. Nevertheless, out of weakness he followed her in her sin. 

In this way we, too, can Fall away: either directly through a temptation of the Devil, or through being persuaded by a non-believer. 

In Genesis we read that God declared war on the devil after he had deceived man: “I will put enmity between your seed and her seed.

He shall bruise your head, and you shall bruise his heel” (3.14-15).

The “seed” here is Christ, and God promises here that while Christ would be bruised in His heel – that's , crucified on the Cross – He would nevertheless bruise the devil’s head – that's , destroy his power by His descent into hell.
