In the 2nd century CE, the Christian theologian Marcion composed a work (now lost) entitled Antithesis. In the Antithesis, Marcion set out in detail and discussed at length the contradictions between the Old Testament and New Testament.[122] The Old and New Testaments, Marcion argued, cannot be reconciled to each other. The code of conduct advocated by Moses was "an eye for an eye", but Jesus set this precept aside.
