Which statement best describes mortal sin?

• A. Mortal sin is a serious sin that completely rejects God's love and separates us from God
• B. Mortal sin is always forgiven automatically
• C. Mortal sin is the same as venial sin
• D. Mortal sin has no eternal consequences

Answer: (A)

Mortal sin means a grave action done with full knowledge and deliberate consent that destroys charity in the soul and breaks our relationship with God. Because it severs that bond, it isn’t forgiven automatically—repentance and usually the sacrament of reconciliation are needed to restore grace. It’s different from venial sin, which is a less serious fault that weakens our love for God but doesn’t completely sever the relationship. And there are eternal consequences if mortal sin is not repented, since it involves turning away from God’s grace. The statement that mortal sin is a serious sin that completely rejects God's love and separates us from God best expresses this understanding.
