Any basic study of biblical doctrines of theology will show that ultimately all doctrines, directly or indirectly, have their basis in the Book of Genesis. In John 5:46–47 Jesus Christ said: "For had ye believed Moses, ye would have believed me: for he wrote of me. But if ye believe not his writings, how shall ye believe my words?" Jesus was emphatic that the writings of Moses had to be accepted to understand what He was saying because all the doctrines He taught were founded in Genesis. For instance, in Matthew 19:46 we read of His answer to the question about divorce that concerned marriage: "And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, and said, for this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder."

Marriage has its foundation in Genesis the first marriage God ordained is of Adam and Eve. To understand the meaning of marriage one must understand and accept its literal basis and origin as contained in the Book of Genesis.

Christ died on a cross because of sin and death and the necessary shedding of blood for the remission of sins. The origin and basis of this is in the Book of Genesis. We wear clothing because God gave clothes because of sin. We read this in the Book of Genesis. To understand Christian doctrine we must understand the foundations of doctrine given in the Book of Genesis. If Genesis cannot be taken literally, there is no foundation for Christian doctrine therefore, Christian doctrine no longer has meaning.

Many people try to say that in the New Testament Jesus was only quoting the writings of His day that He did not believe Genesis to be literal. They say that because the Jews happened to believe in the writings of Moses and in Genesis, Jesus just quoted this to go along with them. However, the Bible also teaches us that Jesus Christ is "the way, the truth and the life" (John 14:6). Jesus is the truth. To say that Jesus would knowingly teach "myth" as fact is to call Jesus Christ a liar. Jesus Christ was not just a man; He was not a sinner; He was the perfect "God-Man." Christians who say that Jesus was only quoting the myths of the day should be careful not to be calling Jesus a liar.
