In Christian history, St Dymphna's life story is quite significant. Her father's madness and her refusal to be part of his immoral plan represent the struggle between good and evil. Also, she is a symbol of purity and steadfastness. Her martyrdom became an example for Christians to stay true to their beliefs no matter what difficulties they face. Moreover, as a patron saint of mental illness sufferers, it's like she's there to give hope and comfort to those in distress, just as she faced distress in her own life.
St Dymphna is regarded as a patron saint of those with mental illness. Her life story shows her strength in the face of her father's insanity. It also symbolizes the victory of faith over paganism.
