What role does religion play in a family in the glass castle?

In "The Glass Castle," religion plays a complex role in the Walls family dynamic. While the children are exposed to spiritual beliefs through their grandmother's influence, their parents, particularly Rex and Rose Mary, exhibit a more ambivalent attitude toward organized religion. This creates a sense of spiritual confusion for the children, as they grApple with their lack of stability and moral guidance amidst their parents' unconventional lifestyle. Ultimately, religion is portrayed as both a source of comfort and a point of contention within the family.
