Pauline Christianity is the Christianity associated with the beliefs and doctrines espoused by Paul the Apostle through his writings. Most of Christianity relies heavily on these teachings and considers them to be amplifications and explanations of the teachings of Jesus. Others perceive in Paul's writings teachings that are different from the original teachings of Jesus documented in the canonical gospels, early Acts and the rest of the New Testament, such as the Epistle of James.
"Pauline Christianity", as an expression, first came into use in the 20th century among scholars who proposed different strands of thought within Early Christianity, wherein Paul was a powerful influence. It has come into widespread use among non-Christian scholars, and depends on the claim that the form of the faith found in the writings of Paul is different from that found elsewhere in the New Testament, but also that his influence came to predominate.
Proponents of the perceived, distinctive Pauline form of Christianity, include Marcion of Sinope, the 2nd century theologian and excommunicated heresiarch, who asserted that Paul was the only apostle who had rightly understood the new message of salvation as delivered by Jesus Christ. Opponents of the same era include the Ebionites and Nazarenes, Jewish Christians who rejected Paul for straying from Second Temple Judaism.
Reference is made to the large number of non-canonical texts, some of which have been discovered during the last 100 years, which show the many movements and strands of thought emanating from Jesus' life and teaching or which may be contemporary with them, some of which can be contrasted with Paul's thought. Of the more significant are Ebionism and Gnosticism. However, there is no universal agreement as to Gnosticism's relationship to Christianity or to the writings of Paul. The expression is used by modern Christian scholars, such as Ziesler and Mount, whose interest is in the recovery of Christian origins and the contribution made by Paul to Christian doctrine, Christian Reconstructionism and Restorationism.
