The New Testament is the second major part of the Christian biblical canon, the first part being the Old Testament. Although Christians hold different views from Jews about the Old Testament, Christians regard both the Old and New Testaments together as sacred scripture. The contents of the New Testament deal explicitly with first-century Christianity. It reflects and serves as a source for Christian theology and morality.
