The Church History of Eusebius 190The Heterodoxy of Novatus.
Open in the reader"For with good reason do we feel hatred toward Novatian, who has sundered the Church and drawn some of the brethren into impiety and blasphemy, and has introduced impious teaching concerning God, and has calumniated our most compassionate Lord Jesus Christ as unmerciful. And besides all this he rejects the holy baptism, and overturns the faith and confession which precede it, and entirely banishes from them the Holy Ghost, if indeed there was any hope that he would remain or return to them."
