What is the theme in The Amen Corner by James Baldwin?

Although not one of the play's most prominent themes, the impact of poverty permeates the play as an underlying condition of the lives of the characters. Margaret berates Brother Boxer for taking a job driving a liquor delivery truck, asserting that it is sinful of him to spend his day providing liquor to people. Sister Boxer, Brother Boxer's wife, however, complains that Margaret is not taking into account the importance of earning a living and supporting a family.
