From Wikipedia
A mortal sin is, in Christian theology, a gravely sinful act that leads to damnation if a person does not repent before death. It is also referred to as a deadly, grave, or serious sin. The concept is found in both Catholicism and Lutheranism. In Catholic theology, a mortal sin separates a person from God's saving grace. Three conditions must be met for a sin to be considered mortal: the act must involve "grave matter", be committed with "full knowledge", and be performed with "full and deliberate consent".
