Which personal loss inspired Metallica's song “The God That Failed” on The Black Album?

Metallica's song “The God That Failed” was inspired by the death of James Hetfield's mother.

Hetfield's mother followed Christian Science beliefs and did not seek conventional medical treatment for her cancer. She died in 1980, when Hetfield was a teenager. The experience later became the central subject of “The God That Failed,” whose lyrics criticize the religious beliefs that Hetfield believed prevented her from receiving treatment.

The song's title and imagery express anger, grief, and disillusionment rather than presenting a simple devotional theme. Its heavy, deliberate arrangement fits the album's generally darker and more introspective lyrical direction.

The song is sometimes confused with Metallica material connected to Cliff Burton, the band's former bassist who died in a 1986 bus accident. Burton's death profoundly affected Metallica, but it is not the personal event behind “The God That Failed.” The track was written and recorded for the 1991 self-titled album.
