Novatianism
The Novatianists were early Christians followers of Novatian, who held a strict view that refused readmission to communion of Lapsi, those baptized Christians who had denied their faith or performed the formalities of a ritual sacrifice to the pagan gods, under the pressures of the persecution sanctioned by Emperor Decius, in AD 250. The Novationists were declared heretical.
