MARCION.

[Endnote 204:1] Of the various chapters in the controversy with which we are dealing, that which relates to the heretic Marcion is one of the most interesting and important; important, because of the comparative fixity of the data on which the question turns; interesting, because of the peculiar nature of the problem to be dealt with.
We may cut down the preliminary disquisitions as to the life and doctrines of Marcion, which have, indeed, a certain bearing upon the point at issue, but will be found given with sufficient fulness in 'Supernatural Religion,' or in any of the authorities.
As in most other points relating to this period, there is some confusion in the chronological data, but these range within a comparatively limited area.

The most important evidence is that of Justin, who, writing as a contemporary (about 147 A.D.) [Endnote 205:1], says that at that time Marcion had 'in every nation of men caused many to blaspheme' [Endnote 205:2]; and again speaks of the wide spread of his doctrines ([Greek: ho polloi peisthentes, k.t.l.]) [Endnote 205:3].

Taking these statements along with others in Irenaeus, Tertullian, and Epiphanius, modern critics seem to be agreed that Marcion settled in Rome and began to teach his peculiar doctrines about 139-142 A.D.This is the date assigned in 'Supernatural Religion' [Endnote 205:4].
