Today there is a pervasive indifference to the question "What is the Christianity?"This is a serious situation because there are numerous false or only partly false or onlypartly true and partly false versions of Christianity in the world. This indifference is also anindication of one's indifference to the God. A person cannot be indifferent to the God Whoholds his future in His hands and has power to determine his ultimate destiny, and about thetrue religion that God has revealed for mankind.The author of this book believes that neither the Roman Catholic Church nor the currentProtestant Churches are the true church that represents the True Christianity althoughthe Protestant denominations are truer to the Christianity of the New Testament than theCatholic Church. The renowned Catholic theologian Hans Kueng pointed out the deplorableproblems of the catholic Church and called for the reform of the Church in his book TheRoman Catholic Church(2001).The True religion of God must be preserved intact and this preservation is the greatest dutyof the Christians and the church to God.According to prophets of God, "Justice and Mercy" and the pure preservation of the Truereligion of God are the two main concerns of God, and God laments the gullibility and blindsubmission of people to wicked religious leaders.The author of this book is a retired minister of the United Church of Canada and holds a Th.D. from the University of Toronto. In 2008 he published The Roman Catholic Church - ACritical Appraisal through the Xulon Press.
