Original sin refers to the belief that all humans inherit a sinful nature due to the disobedience of Adam and Eve in the Garden of Eden, as described in the Bible. This concept is central to the Christian understanding of the need for redemption and salvation through Jesus Christ. Mortal sins, on the other hand, are considered to be serious offenses against God that result in the loss of sanctifying grace and can lead to eternal separation from God if not repented for. In Catholicism, mortal sins are distinguished from venial sins, which are less serious offenses. **

Examples of unforgivable sins may include blasphemy, apostasy, or certain forms of intentional harm or betrayal.
