The world today would contend that what we believe is not anymore important, so long as we live in peace, love and harmony. We can survive, according to them, even if we do not insist our stand regarding certain issues. True as it may seem, but telling people what we know and what we live for is an indication of where we are going. How about you? What do you believe? The 50 treatises written in this book are focused on telling the reader what the Church of Christ believes. For those who have read the book "What Must We Know About the Church of Christ", this sequel aims for the same thing - to glorify His word and His Name. Peter advises in his first letter to "sanctify the Lord God in [our] hearts, and always be ready to give a defense to everyone who asks [us] a reason for the hope that is in [us], with meekness and fear" (1 Peter 3:15). So with all humility, the facts are presented here with regards to what the Church of Christ believes ever since it was established almost 2,000 years ago. These primitive beliefs sprung from the Bible's claim that no man can lay again any foundation other than the one already laid, which is Jesus Christ.
