Lupus
According to Henry W. Wright
Wright’s account in the book and a supplementary Be in Health article.
Possible spiritual roots
Wright names intense self-hatred, self-conflict and guilt.
Possible additional factor
According to the book, performance pressure may be an additional element.
Be in Health account
The Be in Health article “Specific Profiles of Diabetes 1 and Lupus” particularly emphasizes guilt and self-accusation.
Wright and Be in Health describe autoimmune diseases as a possible physical counterpart of this pattern: the body recognizes its own tissues as a target of attack.
Spiritual response
The spiritual response leads toward receiving God's love, forgiveness, rejecting the false verdict of worthlessness, and prayer for healing and renewed identity.
