How does Ngugi portray Christianity in the book Petals of Blood?

Although the critique of Christianity in the novel is not as overt as are its social and political indictments, it seems clear that Ngugi means to point out the hypocrisy that attends many forms of Christian religious practice. There are no sympathetic portrayals of Christians in the novel. Ezekiel Waweru and the Reverend Jerrod Brown are seen as using Christianity to further their own material interests. Both have adopted the Christianity of the colonial masters and perpetuate the inequality of their system of values. When the villagers first encounter Reverend Jerrod Brown they assume he must be a white European because of his name. He offers them no help with the sick child, Joseph, nor does he give them food, and tells them they need only eat "the food of the spirit, the bread and fish of Jesus." Waweru has adopted the Christianity of the missionaries because it is more profitable for him to do so, but shows no Christian compassion to his son, daughter, or the laborers on his land. The Christian Lillian is also presented as a crazed fanatic who ignores the problems of this world by emphasizing life in the next, a strategy which she eventually gets Munira also to adopt.
