We learn further that Anicetus as a mark of special honour allowed Polycarp to celebrate the Eucharist in the church, and that many Marcionites and Valentinians were converted by him during his stay in Rome.
In the work Against Valentinians, chap. xxxix., he speaks of the " great sacrament of the name," here rendering the Greek word µvo riipcov, mystery.
There are many indications early in the 2nd century of a tendency towards the recognition of a single Gospel; for instance, there are the local Gospels according to Hebrews, according to Egyptians; Marcion had but one Gospel, St Luke, the Valentinians preferred St John and so on; Tatian reduced the Four Gospels to one by means of a Harmony, and it is possible that something of the kind may have existed before he did this.
The demiurge of the Valentinians always clearly bears the features of the Old Testament creator-God.
Though conspicuously uniting faith in Christ with spiritual maturity, there are evidences that, like other Valentinians, Heracleon did not sufficiently emphasize abstinence from the moral laxity and worldliness into which his followers fell.
When the Christians in the eastern part of the empire destroyed a Jewish synagogue and a church belonging to the Valentinians, Theodosius gave orders for the offenders to make reparation.
