What's the name of a devout believer?

A saint, who is virtuous in behavior and life, can set an example for others. In Roman Catholicism, Christians must go through the sacrament procedure before they can be declared saints. In this case, this title confirms that the Roman Catholic Church believes that this man has ascended to heaven and deserves respect. It is the name given by Christian parties to dead priests and believers. There are both historical figures and legends, and they are considered noble and supernatural. Its ruins and cemeteries often become objects of worship. Some saints are famous for their noble conduct, and their representative is Francis. He gave up his rich life all his life and was content with poverty. He regards poverty, chastity and humility as the primary conditions for acquiring spiritual wisdom. Another kind of saints are prophets and prophet reformers, and the representative figure is the apostle Paul. Paul made great contributions to the development of Christianity from Judaism to the world religion, so he was honored as a saint by Catholicism, Orthodox Christianity and Protestantism. Others, because of carrying forward religious traditions and theories, have a great influence on later generations, and are also honored as saints by later churches, such as Thomas Aquinas, a Dominican in the West.
