Nicene and Post-Nicene Fathers: Series II/Volume III/Lives of Illustrious Men/Gennadius/Nestorius the heresiarch

the heresiarch, was regarded, while presbyter of the church at Antioch, as a remarkable extemporaneous teacher, and composed a great many treatises on various Questions, into which already at that time he infused that subtle evil, which afterwards became the poison of acknowledged impiety, veiled meanwhile by moral exhortation. But afterwards, when commended by his eloquence and abstemiousness he had been made pontiff of the church at Constantinople, showing openly what he had for a long while concealed, he became a declared enemy of the church, and wrote a book On the incarnation of the Lord, formed of sixty-two passages from Divine Scripture, used in a perverted meaning. What he maintained in this book may be found in the catalogue of heretics.
