The Book of Genesis represents a matter that is important to both Judaism and Christianity. Fall of Adam and Eve represents a fall that everyone will experience eventually. Actuality of sin is closely related to every human.The Book of Genesis represents Semitic view of that universal issue. The issue is brought through portrayal of events under the tree of knowledge of good and evil.In this study, scrutinizing theories about interpretations of the original sin, we are trying to provide answers on some of the questions that every human, believer, asks himself. Where sin comes from? Why sin? What the original sin is in its essence? Is sin physical or spiritual in the nature? Does sinfulness exist or not?Sinfulness, into which humans are born, vanishes in the sacrament of baptism. In that sacrament, human being born with the seed of sin, is taken out of impurity and immersed into the grace of new Adam Christ. Human is created as good and sacred, he is God's child and made in God's image. Therefore banishment in the Book of Genesis only represents fatherly reprimand of ungrateful and arrogant child. In the light of the New Testament we see that the fatherly reprimand is actually transfused into the expression of ultimate love through Christ's suffering, death and resurrection, fallen human is redeemed and reverted to state of grace. Much stronger state of grace through Christ than it was state of sin through Adam.
