Genesis does not give an author’s name
Unlike many New Testament letters, Genesis does not begin by telling us who wrote it. Its opening moves straight into God creating the heavens and the earth, then follows Adam and Eve, Noah, Abraham, Isaac, Jacob, and Joseph. So Scripture does not provide a line in Genesis saying, “Moses wrote this book.”
That means it is wise to speak clearly but humbly. The traditional answer is Moses. Yet the text of Genesis itself leaves the author unnamed, and it draws our attention first to God, not to the human writer.
Why Moses is the traditional answer
Genesis is the first book of the Torah, also called the Law or the five books of Moses. Throughout the Old Testament, Moses is shown writing down God’s words and instructions for Israel. At Sinai, Moses recorded the words God had given to the covenant people (Exodus 24:4). Near the end of his life, he also finished writing the law and gave it to the Levites for safekeeping (Deuteronomy 31:24-26).
Jesus likewise spoke of Moses’ writings. When challenging people who searched the Scriptures but resisted him, Jesus said that Moses wrote about him. He then connected believing Moses’ writings with believing Jesus’ own words (John 5:46-47). This is a major reason Christians have historically linked Moses with Genesis as well as Exodus, Leviticus, Numbers, and Deuteronomy.
For had ye believed Moses, ye would have believed me: for he wrote of me.
Did Moses write every part alone?
Faithful Christians have answered that question in different ways. Many believe Moses wrote Genesis directly, guided by God’s revelation. Others think Moses may have gathered and arranged earlier family records or oral accounts, again under God’s guidance. Genesis contains repeated family histories and generations, which naturally preserve the memory of God’s work through particular people and households (Genesis 5:1; Genesis 10:1).
The Bible does not explain the whole writing process. It does show that God spoke through prophets and that Scripture came as people were moved by the Holy Ghost, rather than simply recording human ideas (2 Peter 1:21). So the central question is not merely how sources were used, but whether God faithfully gave his word through them.
Why the question matters
Knowing that Moses is the traditional author can help place Genesis within Israel’s story. It was not written as a detached collection of ancient tales. It introduces the God who created all things, judges evil, makes promises, and begins a covenant family through Abraham. Those promises continue through the rest of the Bible.
Still, Genesis does not depend on our having every detail of its composition settled. Jesus treated the early chapters as meaningful history, referring to God making humanity male and female from the beginning (Matthew 19:4). Genesis invites you to meet the God it reveals. Read it slowly, notice what it says about him, and let its first pages set the stage for the whole biblical story.
And Moses wrote all the words of the Lord, and rose up early in the morning, and builded an altar under the hill, and twelve pillars, according to the twelve tribes of Israel.
