 In the bitter quarrel between St. Jerome and Rufinus concerning Origenism, Chromatius, while rejecting the false doctrines of Origen of Alexandria, attempted to make peace between the disputants.He maintained ecclesiastical communion with Rufinus and induced him not to answer the last attack of St. Jerome, but to devote himself to new literary works, especially to the translation of the "Ecclesiastical History" of Eusebius.Chromatius opposed Arianism with much zeal and rooted it out in his diocese.
