<bot>: Yes, some adherents to Christianity in China are historic enemies of the Catholic Church. Christianity in China is comprised of several different groups including: Protestants, Catholics, Evangelicals, and Orthodox Christians. Catholics have been at war with Protestants throughout history. The 1572 St. Bartholomew's Day Massacre saw thousands of Protestants killed by Catholic mobs. So yes.
