I. INTRODUCTION The 19th century was a period of great revolutions both in the fields of agriculture, communications, transport, technology, markets and industry. It is in this period that the collapse of great empires such as Portugal, Spain, the Mughal, China and the kingdoms of the Holy Roman Empire occurred and in their place the German, British, Japanese and United States kingdoms arose. Great philosophical and religious leaders also dotted this century, such as William Booth; the founder of the Salvation Army, Karl Max, Ellen White, the great philosopher John Stuart Mill, among others. This century also marked the beginning of great evangelical revivals in a number of Protestant churches and countries throughout Europe and America. It also marked the beginning of the effects of modern scientific theory and reasoning on Christian thought and beliefs. Scientific theories such as Darwinism have had a major impact on churches, leading many Christians to question some of the beliefs and values ​​they once held. These theories led to a mass shift of early Christians from regular, traditional observance of religion and belief in Christian teachings, to secularism and belief in a “personal god.” As the radical effects of scientific secularism continued to be felt in the Christian churches, several theologians and scholars such as Friedrich Schleiermacher rose up to defend Christianity. Unfortunately, his defense did not protect Christianity from criticism as it led to the emergence of liberal theology and liberal Christianity. Liberal theology is a flexible method of understanding and knowing God through the use of the Scriptures, making use of the same hermeneutics and principles... middle of paper... Han on the authority of the Church or the Scriptures. In conclusion, the attempts of 19th century theologians and scholars to defend the Bible from the influence of Darwinism were no defense. This attempt was a simple way to accommodate the beliefs in humanism that Darwin portrays in Christianity, which ultimately led to the emergence of a new religion; liberal Christians. This compromise is what has led to the ongoing attacks on the authority of the Bible, leading to further splits in Christianity. Works Cited Ayers, Philip, E. What Ever Happened to Respect?
