I couldn't find that much info on this paticular movement except for this view that it was a heresy:

NOVATIONS were Montanists who took their name from a priest and Anti-pope, Montanus.
He preached that those who fell from grace were out of the church forever, as opposed to the orthodox position that by sincere contrition and repentance the fallen might be readmitted. In addition they believed that the value of the sacraments depended on the purity and worthiness
of the priest administering the rites. In time they merged with the Donatists who sprang up in Carthage, 4th century in a split with Rome over the failure of a their man to win the bishop's seat.
