How do the churches get involved in the revolution? How do the people and SIM respond?

In Chapter Ten, Padre Gabriel is introduced as Padre de Jesus' replacement. He gives a revolutionary sermon. In this chapter, we learn that the church, as an institution, has "thrown in its lot with the people." We also learn that SIM is noticing. The next Sunday, mass is disrupted by prostitutes attending the service, and the next week, the contents of latrines are dumped in the confessional before Sunday morning confession.
