According to Marcion, the god of the Old Testament, whom he called the Demiurge, the creator of the material universe, is a jealous tribal deity of the Jews, whose law represents legalistic reciprocal justice and who punishes mankind for its sins through suffering and death. In contrast, the god that Jesus professed is an altogether different being, a universal god of compassion and love who looks upon humanity with benevolence and mercy. Marcion also produced a book titled "Antitheses", which is no longer extant, contrasting the Demiurge of the Old Testament with the Heavenly Father of the New Testament.
