Irenaeus as the mastermind of the canonicl collection, later known as the New Testament, creates the foundation for the later picture of a chronological development from Jesus and his disciples through the first bishops and the institutionalization of the Church. However, he himself hardly relates to these writings as historical evidence, but rather engages in an anti-heretical use of some of them to endorse church orthodoxy. It is this apostolic foundation that provides the rule of truth against which he sees the heretics struggeling, driven by evil forces in an apocalyptic scenario.
