Read the treatise of Theodoret of Cyrrhus _Against Heresies_, from
the time of Simon[195] down to those which sprang up in his own age.
It is dedicated to a certain Sporacius,[196] who was fond of hearing
about such matters. It goes down to Nestorius and his heresy, on
which he pours forth unmitigated censure, and even farther, to the
heresy of Eutyches. In the last of the five books which the treatise
contains, he gives a summary of divine and orthodox doctrine
compared with idle heretical talk, showing that it is not to be
confounded with the latter, but is pure and irreprehensible. The
style is clear and free from redundancies.
