Gnosticism emerged as a mixture of platonic thought with Greek, Egyptian and Mesopotamian mythology and Christian doctrine. They believed in a good god and evil god, the latter of whom created the material world. To be saved, you had to be initiated into a special knowledge – gnosis – that is free of matter. Christ was sent as the Logos of the good god to free us from the material world created by the evil god often associated with the God of the Old Testament. Among the prominent figures of Gnosticism was a man named Marcion. Marcion composed an edited version of the Gospel of Luke and the epistles of Paul omitting anything about the material world. Marcion along with other figures preceding him like Valentinus were vehemently opposed by the Church in figures like Ignatius of Antioch and Irenaeus of Lyons. With Irenaeus of Lyons’ opposition to Marcion, came the realization of the necessity of forming a list of books accepted the Church.
