Throughout the centuries, the Church has faced challenges, including persecutions, schisms, and the rise of various denominations. Important events like the Reformation and the Council of Nicaea have significantly influenced Christian beliefs and practices. Understanding church history helps us appreciate the rich heritage and diverse expressions of faith today.
