“I know all about the honour of God, Mary Jane, but I think it’s not at all honourable for the pope to turn out the women out of the choirs that have slaved there all their lives and put little whipper-snappers of boys over their heads. I suppose it is for the good of the Church if the pope does it. But it’s not just, Mary Jane, and it’s not right.”
These paragraphs reveal the selfish of the church, which is similar to the theme of The Sisters. It contains some topic words such as "God" and "church". I think we can use the topic model to find the topic words from the chapters before The Dead to form a topic model of Dubliners and finds the supply the topic model to prove that The Dead contained many themes that occurred before.
