The theory of original sin means that Christianity believes that everyone is born guilty, and their sins come from their ancestors - Adam and Eve. They broke their agreement with God and ate from the tree of the knowledge of good and evil. This disobedience brought sin, guilt and shame. Later generations were affected by Adam's sin and were born with a sinful nature. Only by atonement can they be reborn. However, if love is not enough, even if it is a sin, we will never admit it.
Intention: Descendants are affected by Adam's sin and are born with a sinful nature. Only by atonement can they be reborn. But there are some sins, which are not sins, but rather death, denial, and repentance.
