Christianity began as a simple faith with all believers brothers and sisters in Christ. Growth brought a hierarchy of priests and prelates to formulate doctrine and govern the churches. This hierarchy soon focused more on power and pelf than spirituality. In the Eleventh Century the Roman bishop's claim to supremacy over all clergy and communicants drove away Eastern Christendom. By the Sixteenth Century the hierarchy's corruption, venality, immorality and unBiblical doctrines led to The Reformation: The Inquisition and campaigns against "heretics" slaughtered hundreds of thousands of God-fearing men, women and children. And even today its demand for conformity to unScriptural dogmas in alienating millions.
