List of Heresies in Catholicism - Early Christianity

Early Christianity

Traditionally, orthodoxy and heresy have been viewed in relation to the "orthodoxy" as an authentic lineage of tradition. Other forms of Christianity were viewed as deviant streams of thought and therefore "heterodox", or heretical. This view was dominant until the publication of Walter Bauer's Rechtgläubigkeit und Ketzerei im ältesten Christentum ("Orthodoxy and heresy in ancient Christianity") in 1934. Bauer endeavored to rethink early Christianity historically, independent from the views of the church. He argued that originally unity was based on a common relationship with the same Lord rather than on formally defined doctrines and that a wide variety of views was tolerated. With time, some of these views were seen as inadequate. He went on to attribute the definition of "orthodoxy" to the increasing power and influence of the Church of Rome. In 1959, Henry Chadwick argued that all Christian communities were linked by the foundational events which occurred in Jerusalem and continued to be of defining importance in the forging of doctrinal orthodoxy. MacGrath comments that historically Chadwick's account appears to be much the more plausible.

For convenience the heresies which arose in this period have been divided into three groups: Trinitarian/Christological; Gnostic; and other heresies.
