What metaphor is used to describe original sin in discussions?

The metaphor of a spiritual cancer effectively captures the pervasive and destructive nature of original sin. Just as cancer is known for spreading throughout the body and impairing its functions, original sin is seen as something that infiltrates human nature, corrupting it at a fundamental level. This metaphor highlights the idea that sin is not merely an isolated action but a deeper condition that affects the entirety of a person's being, leading to ongoing spiritual and moral decay.

By likening original sin to cancer, the discussion emphasizes the seriousness of the condition and the necessity for a transformative solution—similar to how one might seek medical intervention to address cancer. This understanding underscores the theological perspective that highlights the need for redemption and healing through grace, illustrating the gravity of sin's impact on humanity.
